and… composition

2011-shotbyjake-com-7019

[above: Eli Schmidt composing some solid shots at NYFW]

Now that we have a solid understanding of the interaction between the settings affecting exposure, let’s move onto composition. We will start by learning about the rule of thirds, negative space, and framing. Then finish up chatting a bit more about how depth of field and focal length can be manipulated to create different effects.

Rule of thirds

The rule of thirds is just an articulation of something that most people tend to do naturally anyway. That is, to try to create balance through symmetry or asymmetry when framing up a shot. The rule of thirds says: “an image should be imagined as divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines, and that important compositional elements should be placed along these lines or their intersections.”

To illustrate this concept, here is an animated GIF that I borrowed from Wikipedia  under cc license. Notice how the horizon tracks the bottom horizontal divider almost exactly. The tree trunk does the same with the right hand vertical dividing line.


Creating balance in composition is, in my opinion, the element that allows an image to convey purpose. Squaring up the subject directly in the center of a portrait is the most distilled example of this. There is no doubt that people will read loud and clear what is meant to be seen in the image. There are obviously more ways to do this than centering the subject. The rule of thirds is a guideline that can help retain aesthetics when we are getting creative with composition. All of this is not to say that centering the subject and using the rule of thirds are the only two options for making an interesting composition. They are just some tools that can help us, especially when we are trying to explore what our personal compositional style is.

Negative space

The example above was shot by my cousin Tif, on Antelope Island. It is a fantastic example of how negative space is used to draw attention to the subject. Plus, who isn’t a sucker for a gorgeous gradient blue sky? Negative space doesn’t always have to be empty.

Framing

In this case, we aren’t referring to the type of framing that is done after getting such an amazing shot, that we print it and stick it in a frame on the wall. Instead, we are referring to framing subjects within the composition, that draw attention to the subject. The example below is from the Quikpro surf competition a few weeks ago. Notice how the surfer is wedged nicely between the heads of the two bikini clad onlookers.

Depth of Field

Ok, lets wrap things up discussing depth of field and focal length. As usual, I had planned to shoot a set of images specifically to demonstrate this point, but haven’t found the time. I think that I will probably talk Sam into doing a tutorial with me on this point. Depth of field is another compositional tools that can be used to draw attention to the subject. The image below is a great example of this.

2011-shotbyjake-com-7338

As you will recall, aperture and focal length, combined with distance to subject are the factors that play into determining our depth of field. In the image above, I used a large aperture and long focal length to create a shallow depth of field. Because of the shallow depth of field, all of the models that are ahead or behind the subject, are not in focus. By paying close attention, you probably noticed that I also used this effect in the negative space and framing examples above. As much fun as it is to play around with depth of field, it can be tricky. If you are very close to the subject, with a very shallow depth of field, some of your subject might be out of focus, etc..

To achieve this effect, shoot in either aperture priority mode (AV for Canon), or if we are feeling confident about being able to adjust shutter speed and ISO for correct exposure, use manual mode. Set the f-stop to a low number, like f/4 or lower (note that depending on what lens is being used, f/4 might be the lowest). Ideally it is nice to be using either a prime lens, or a zoom with a constant aperture. What do I mean by that? A lot of zoom lenses have a variable maximum aperture setting depending on focal length (how far the lens is zoomed in or out). So, to eliminate some frustration from experimenting with depth of field, using a prime lens is probably the safest way to go. If you don’t have a prime, I recommend for Canon users purchasing the 50mm f/1.8. It is under $150.

Ok, now that we are in aperture variable or manual mode, let’s change our AF screen so that we only have a single point in the center of view finder. For Canon users, this is done by using the button at the top right of the back of the camera with the icon that looks kind of like a checker board. Click through here for instructions with Nikon. That will allow us to focus on a specific point, and not allow the camera to decide for us. Finally, change the AF mode to “one shot” or the Nikon equiv. We are ready to go.

As a general rule of thumb, here are the basics to remember–

Larger aperture (smaller f-stop number)= shallower depth of field.

Greater focal length = shallower depth of field.

Less distance to subject = shallower depth of field.

Let’s play out a quick scenario: We are shooting some portraits using a 50mm lens, trying to play up the shallow depth of field, the aperture is wide open. But, the photos are crap because only the end of the subject’s nose is in focus. What are the options? Option 1— close down the aperture a bit (choose a higher f-stop number). But, we don’t want to choose a higher f-stop because it is low lighting and we can’t afford to use a slower shutter speed or boost the ISO because it will cause camera shake or unwanted noise. Ok, let’s try Option 2— back away from the subject until the depth of field increases enough to have the subject’s entire face in focus. But, we don’t want to back away too far, because it throws off the desired composition by having all of that distracting stuff in the periphery. No worries, we can go with Option 3— let’s get rid of the 50mm and use a 100mm instead. Now we can back away far enough to have the whole face in focus, but still have the composition tightly cropped on the subject. Hey, I think that I just scripted out the next tutorial. Hehe.

Homework– experiment with composition using the rule of thirds, negative space or framing.

Extra credit– Combine one of the homework techniques in the line above with a depth of field effect.

Now get out and shoot!

…you need to just chill out, go up on the roof and get a shot of the only pink cloud in the sky.

happy fashion week (cont’d)

2011-shotbyjake-com-0693bw

The image above is currently one of my favorites shots from this iteration of NYFW. It was back stage at a Native Son show. Normally all of the back stage stuff that you get is the same. It is generally a bunch of candid images of people getting hair and makeup done, PR people yelling at other PR people in their headsets, etc.. My favorite overheard back stage conversation so far was “OMG, Yuri got arrested! We need to do a model count right now!”

Anyway, the reason that I like the image above so much, is because this particular show was off site at Pier 59 in Chelsea. The windows from the hair/makeup area of back stage opened onto the roof. So a bunch of the more Rat Pack-like models ducked out to have a quick butt. Another shot of the smoke break, below-

I’m hoping to have more images from these sets up on my photo blog by this weekend.

Oh yeah, wait. One more. I really liked this one from Billy Reid.

2011-shotbyjake-com-8686

I wish that it wouldn’t have been so dark in there. I had to have the ISO jammed all of the way at like 1200 or something. So, this image isn’t very sharp. But I still really like the moodiness.

More exposure fun– aperture

2011-shotbyjake-com-0220

Hello again! Sorry that this installation of the series is a day late (and probably a buck short).  I’m also going to apologize that there is no tutorial video to accompany this post. Sam is currently holding things down in Finland for the next couple of weeks. Hopefully we will shoot some more videos when he returns stateside. Until then, I hope that text and images can tide us over.

As much fun (and important) as shutter speed is. The aesthetic and mood of most of our images will mostly likely be dictated by our aperture settings. Candidly, I will admit that having a good handle on aperture settings probably trumps fully understanding shutter speed. Why? Because there are so many factors tied into the aesthetic quality of the image, that depend on aperture, besides just exposure. The main one that I’m referring to, is of course depth of field, which is sometimes referred to as focal plane. Those are a couple of terms that you will probably want to remember, especially depth of field.

Exposure

Ok, just to review the basics about aperture settings as they pertain to exposure– Remember example of filling the bucket. The aperture is akin to the size of the hose in the bucket example.

Large aperture (low f-stop number, i.e. f/1.4)= lets larger volumes of light in for faster exposure.

Small aperture (high f-stop number i.e. f/16)= lets smaller volumes of light in for slower exposure.

Good? Ok, good.

Depth of field

Ok, I really meant to set up some shots this weekend to demonstrate the different effects that can be achieved with different aperture settings. Alas, I was running around like a chicken with its head cut off, and I didn’t want to postpone this installment any longer. So, I’m going to use some images (still recent) from former shoots that demonstrate the differences. First of all, what is depth of field? Great question. There are scads of equations that you could memorize to explain it. But, here is the simplest explanation: depth of field is the distance between the closest object (to the lens)  that is in focus, and the furthest object that is in focus. I was going to scratch out another crappy diagram, but there was a pretty good one on Wikipedia under a cc license. So I used it instead.

depth_of_field_diagram

In addition to aperture size, focal length and distance to subject play into depth of field. For the moment let’s just concentrate on aperture.

Large aperture (low f-stop number, i.e. f/1.4)= shallow depth of field (blurry foreground and background).

Small aperture (high f-stop number i.e. f/16)= deep depth of field (it’s possible to have the entire composition in focus).

Here are a couple of quick examples of different aperture settings. You may remember them from this shoot.

Again, sort of ignoring focal length and distance to subject for a minute. This image was shot at f/4. Notice how the subject is nice and sharp, but the background  is much softer and not in focus (and the same would be true for the foreground, had I included any in the composition).

2011-shotbyjake-com-5136

This image was shot at f/13. Yes it is a much wider angle, as well. But, notice that the cars are in focus and even the far tower of the bridge is a lot more sharply defined.

2011-shotbyjake-com-0515_0

Preview to focal length

And uhhhh, since I used such differently composed images for the examples, we might as well throw in some extra terms, touching on focal length. The sort of “standard” focal length is right around 50mm. So, back in the day if you were to buy a point and shoot that had no zoom (remember, on an SLR, we call this type of lens “prime”), it was probably around 50mm. With a 50mm focal length as a reference, here are two additional terms–

wide angle” a focal length less than 50mm (the second example image above was shot at 20mm). Super wide angle lenses will have some lens distortion. Fish-eye lenses are a good example of that.

telephoto” a focal length more than 50mm, also referred to as a “long lens.” The first example above was shot at 115mm. As a general rule, if the image appears closer when you hold the camera up to your eye than it does in real life, the focal length is probably considered telephoto.

This post was kind of quick and dirty. Next time I will talk about how focal length and distance to subject interplay with aperture to give us the desired depth of field. But for now, let’s recap:  we learned that larger aperture settings give us more light flow and shallow depth of field. Small aperture does the opposite. Now, lets do some homework.

Let’s experiment with aperture. If we want to let the camera do the work on exposure, set the camera to aperture priority mode, “AV” for Canon. If we are feeling adventurous, go ahead and use “M” for manual, keep in mind that you will also have to change the shutter speed on “M” to get the right exposure.

Shoot in a well lit situation, so that you don’t have to worry about under exposing on a small aperture setting. Then shoot one of each–

1. One image with shallow depth of field (with the aperture wide open).

2. One image with everything in focus (the aperture stopped way down).

Extra credit: see how zooming in and out/changing distance to subject affect the depth of field.

Good luck! Feel free to report back.

Quik pro, day 1

2011-shotbyjake-com-6297

I almost didn’t even go out to the comp today, since it was so overcast when I finished my run in the morning. The sun came out soon afterwards, and I got an email from one of my photog friends who said that the conditions were ok. By the time that I arrived in LB, the weather was great, but it was almost high tide, and the waves were kind of crap. I hung out in the press pavilion the whole time and almost didn’t bother getting the camera out. But then I decided that I should probably get a couple of atmosphere shots, at least.

2011-shotbyjake-com-6251

I’m headed out there early tomorrow, hopefully the conditions will be a bit better, since low tide is at like 8 AM or something. I have had worse Labor Day weekends. At least I was able to work on my tan a little bit. Part of me secretly wishes that I could just skip out on fashion week altogether and just shoot surfing all week.

Hawk Vert Jam

2011-shotbyjake-com-6053

Well… this is kind of awkward. I was supposed to be spending the weekend in Southern California. But, as they often do these days, my plans changed at the last minute. Friday was the official kickoff of New York City’s first ever major surf competition. Since Quiksilver is sponsoring it, Tony Hawk put on a vert demo as the inaugural event. The ramp was set up at the end of Pier 59 on the Hudson (14th St.). It was pretty amazing to be able to shoot these guys skating. Like every other kid who grew up skating in the 80’s I was always a massive fan of Tony Hawk. One of the other old school guys at the demo was Kevin Staab. His pro model was the first “real” skateboard that I ever bought. Anyway, that top image of Tony is one of my fav’s of the day. Here are a few more.

Lots of “part 2″s today. This is the piece that I was intending to shoot in DC over the weekend. Since that whole plan was fouled up by the weather. Sam was a good enough sport to step in and rock this messenger bag for me. The lighting was surprisingly good for post-hurricane overcast conditions. I thought about warming the images up a bit, but ultimately I liked them how they were shot. A couple more looks–

What is so awesome about shutter speed? part 2

onlyny-2010-shotbyjake-com-3857bw

Hi. In this edition of the series we are going to chat about shutter speed in low light situations. In the last installation of the series, we discussed shutter speed in well lit situations, and shooting in shutter priority mode. As important as I feel like it is to learn what your camera(s) will do in all of the different settings, we are going to be approaching this segment mostly in full “manual” mode. Please don’t be intimidated. “M” is the most liberating setting that your camera affords you. Embrace it.

This might not be the right place to say this, but lower light makes for much more interesting photos. When we have long shadows, and directional (other than directly over head) light sources,  is when we should be shooting. Some people use the term “golden hour” to describe the hour after sunrise, and hour before sunset. I tend to endorse that term. Images shot during those windows tend to be golden.

Let’s do a brief overview of shooting in manual, but focusing on shutter speed effects. As you most likely recall, the main decision that we need to make when we are choosing a shutter speed, is– “do we want to freeze time, or do we want to show motion?” And actually, as Zach aptly pointed out in the comments of the previous shutter speed post, the question might also be– “do we want to avoid camera shake/unwanted motion blur?”

Ok, switch your camera to “M.” Now we are going to have to set the aperture (f-stop) and the shutter speed. After a little practice, shooting in manual will become second nature. But while we are becoming acclimatized, lets refer to the bucket metaphor as often as we need to. If we are trying to freeze time in low light, we are probably going to want to open up the aperture as wide as our lens goes (and possibly bump up the ISO to compensate for smaller maximum apertures). If we are going for some motion blur, then we can start at a neutral f-stop like f/4, or even f/8. After we take a couple of test shots at our desired shutter speed (based on how low the lighting is), we can adjust the aperture up or down. For long shutter shots, we are probably safe dialing down the aperture as much as we want, as long as we can do a 30 second (or better) shutter speed.

For viewing pleasure, my homey Sam Adams (direct relation to the founding father/brewmaster) was kind enough to make a video of me awkwardly demonstrating how to achieve a few shutter speed oriented effects in low light. As a side note, I have often called on Sam to model product that I’m shooting for editorial stuff. In fact, that is Sam longboarding in the photo at the top of this post. Sorry ladies, he is taken. Please feel free to laugh at how poorly I articulate thoughts on camera (and in real life?). Also, please forgive all of the “uh”s and “um”s. Did I mention that I talk a lot? Anyway this is the first ever Shot by Jake video tutorial. Thanks again to Sam for shooting and cutting this. He did a great job, especially given the fact that we just threw this together in one long take.

Some quick terminology for the tutorial– “prime lens”= a lens that has a fixed focal length (the opposite of a “zoom lens”).

Homework: Shoot something in low light, using shutter speed to show motion.

Extra credit: Shoot a long shutter-speed image at night (of something stationary or moving).

at least it’s thursday

2011-shotbyjake-com-0515_0

I’m currently working on a little lifestyle story featuring one of the brands that HS covers. I shot the first part of it early this morning  (before the monsoon rolled in). These are a few of the images. Hopefully (depending on the weather) I’ll be shooting the second part in DC this weekend.

2011-shotbyjake-com-5168 2011-shotbyjake-com-5024 2011-shotbyjake-com-5173

It’s been a pretty busy week already. I take comfort in the fact that tomorrow is Friday.

 

Summer is fading

2011-shotbyjake-com-0362

A great sign that summer is on it’s way out is when hurricane season arrives. I wouldn’t say that we are already in hurricane season. But, apparently Irene is coming through this weekend. As a side note: the young and impressionable Jake was always curious about how the names of hurricanes were chosen. This was one of scads of technical questions that I was able to ask my dad and receive a true and accurate answer about. In the pre-Google days, I feel bad for people who didn’t have a certified genius for a dad, like I do.

Back on topic, the days are shorter, etc.. I certainly hope that Irene turns out to be all media hype, like every other hurricane that has made it’s way in our direction since I have been a New Yorker. Why? I have some good stuff planned for the next few days. I’m not just talking about my boring old running. I’m supposed to be shooting something tomorrow morning that I’m pretty stoked about. Aside from that, a DC road trip is on the calendar for this weekend. More outdoor activities are slated for DC.

So, I can deal with the fact that the sun is no longer making itself seen until after 6 AM. But Irene, please girl, leave us alone this weekend. Ok? Go ahead and send your siblings through in a couple weeks, so that we have some real waves for NYC’s first real surf competition. But, I know that I’m not just speaking for myself when I plead with you to just turn yourself around and head back out to sea. k, thx.

What is so awesome about shutter speed?

july-4-2010-shotbyjake-com-5877web

[img]

Warning: this post is going to be lengthy.

I’m going to start out this post by referencing a question raised by Melissa in the last segment. She asked “how do you decide what the appropriate settings should be in the moment? Say I’m shooting outside on a bright day, how do I know how low I should set the ISO or how low of an f stop?” Very, very good question. I’m not trying to coach anyone on aesthetics here, but lets shift our thinking a little bit. We can be reactionary photographers, or we can be proactive photographers. To be reactionary, all we need to do is lock the cam into “auto” and let the camera evaluate the situation and make all of the calls. Or….. we can be proactive when see a photo-worthy subject, and think to ourselves “how can I make this shot awesome by interjecting a bit of my own style into the way I shoot this?” Depending on how we answer that question is how we would know which way to skew the settings. If you aren’t quite sure what your personal style is when it come to photography, don’t sweat it. I’m sure that it goes without saying, that one’s style is a very dynamic thing that will constantly change and expand with time, experience and practice, etc.. For those who are having a hard time figuring out where to get started, imitation is always a good place. Think of some of the photos that have recently caught your attention. Decide what it is about them that makes them appealing. Then, practice recreating the appealing aspects in your own work.

Now that we know all of the variables involved in achieving a proper exposure, let’s put that knowledge to use. Let’s play out the scenario described by Melissa, as well as a lower light scenario. Since we are discussing shutter speed in this post, we will address the questions in that context.

Shutter speed in bright light

We are shooting outside on a bright day. We have a great subject that we want to be proactive about and capture an interesting image of. We decide that we are going to make the aperture defer to our shutter speed. For those shooting with SLR’s there is actually a setting that will accomplish this for us. On Canon cameras, it is “TV” mode. I apologize for not knowing Nikon’s shutter priority mode. But I know that Nikon also has one. Nikon ppl, please put the name of Nikon’s shutter priority setting in the comments. In shutter priority mode, the camera will automatically try to adjust the aperture to gain the proper exposure, based on the shutter speed that the photographer has chosen.  But, the photographer will still have to manually select the ISO (unless the camera is on auto ISO [which I strongly discourage]). Since we are shooting outside on a bright day, lets start by dropping the ISO down to like 100. That way we know that we are going to get a nice buttery image with zero noise.

Ok, so we are set on shutter priority mode, with the ISO at or near the lowest setting. Do we want to show motion, or do we want to freeze time? It is going to be a lot easier to freeze time in bright daylight, since our aperture only goes so small. So lets dial up the shutter speed to 1/1000″ That should be fast enough to freeze most motion that humans are capable of. Since it it bright daylight, we shouldn’t have a problem underexposing. This is a great setting for jumping or hair whipping pics–

wedding-dive

The image above was shot by John Holman, who is friends with the gentleman (my amigo Zach) jumping over his bride in the photo. Let’s check out the EXIF data (fn.1)  on this image.

exif1

So, we can see here that John was using a custom program geared towards action, giving priority to shutter speed (sounds pretty similar to Canon’s TV mode). That was a smart move. The shutter speed was 1/800″ and the aperture of f/10 was probably automatically selected by the camera based on it’s light meter. Here is a quick quiz. If John was shooting in TV, and would have had the ISO set to 100 instead of 400, and the shutter speed set to 1000 instead of 800, would the camera have adjusted the f-stop to a higher or lower number to try to get the same exposure?

Motion blur is also possible in well lit situations, but it is more fun in low light, so let’s cover it there. When you learn to do it in low light, you will be able to capture it in any kind of light.

Before we move away from our brightly lit scenario, there is one more idea that I would like to throw out, while we are talking about shutter speed. Why not underexpose? This in an effect that can be very cool. People who see the image will know that it was shot in bright light because of the way that the light is hitting the object in the image. But the photo will be interesting, because instead of being bright and blown out, it will look almost like night time. Here is an awesome example of that–

erinheathertonlead

I wish that I could say that those were my images. Alas, they belong to Enrique Badulescu. Granted there is also some serious post-production work done on these, but it is a good example, no?

I was going to keep dragging this post out, and write about choosing a shutter speed in low light. But since my attention span has expired, I can imagine that a reader trying to ingest all of this would probably also be struggling to pay attention by this point. So, instead lets do an assignment and chat about low light later.

Before we get to the assignment, I would just like to throw in a quick suggestion/technique. One of the coolest things about digital photography, is that it costs just as much money to shoot 100 frames as it does to shoot 1 frame. So, trial and error is our friend. Shoot as many frames as you need to. Term of art– “bracketing.” If we are documenting something that doesn’t allow us time to perfectly dial in the exposure before we start shooting, we can put it about where we think the setting should be– shoot a few frames; then adjust up a bit, snap a few; Adjust down, snap a few. This way we have our bases covered. If the initial guess was a bit off, no worries. We have belt and suspenders by exposing some frames adjusting up and down a bit. One of those shots is bound to be golden.

Here is the homework– Let’s find the sweet spot for freezing time with our shutter speed. Note, this is going to vary depending on how bright of light we are shooting in. So, let’s try it shooting outside during a fairly bright time of day. Set your camera to the shutter priority mode (“TV” for Canon). Start with 1/800″, and play around until you get an image that you are stoked about. Remember, depending on the ambient light, you run the risk of underexposing while using a high shutter speed. The camera can only compensate in f-stops up to the maximum aperture of the lens you are using. But you can always fall back on adjusting the ISO up a notch if you need to.

For extra credit, purposely underexpose in broad daylight. Still in shutter priority mode, run the shutter speed up all of the way, and drop the ISO all of the way. Depending on the ambient light (and your camera’s maximum settings), you may end up with some seriously dark frames at first. So between frames, gradually slow down the shutter a bit until you get an image that you are stoked about.

Link to your images in the comments, if you feel like sharing the results of your homework assignment.

Stay tuned for ideas with shutter speed in lower light situations (for which I’m planning a short action packed tutorial vid to accompany).

1. EXIF data is the information regarding the camera and camera settings that digital cameras automatically store in the image file. It can be viewed in most photo editing programs. Unless the EXIF data has been scrubbed from the file, you can even download images from the interwebz, and see what camera settings were used to capture the image.

Lightning

2011-shotbyjake-com-4700_0

I have never been able to successfully shoot lightning… until tonight. I mean, at least marginally successfully. These images aren’t blowing my mind or anything. But they are definitely better than the crap that I have captured in the past. When I walked in the door from this evening’s run, the whole hallway lit up. Then it happened again like 3 times, before I even got to the bedroom. So, without even changing out of my nasty sweaty running garb, I grabbed a cam and a tripod and scurried up to the roof (which I hear is one of the smartest places to be in a lightning storm). Anyway, the flashes were so frequent and consistently located, that it was almost like shooting fish in a barrel. When the storm started to move more directly overhead, I felt like it was time to call it quits and retreat. Here is one more shot of a lightning illuminated cloud.

2011-shotbyjake-com-4727

let’s talk about exposure

Ok, so here we go. For the first part in this series, I have decided to discuss exposure (not the indecent kind).

Exposure is kind of the corner stone of photography. I mean, that’s what photography is– exposing film (or a light sensitive chip) to light. There are three variables that determine the exposure of an image (not counting post-processing). They are ISO, Shutter Speed and Aperture. The “exposure triangle” is a useful way that I have seen it explained before. I drew a little diagram with a marker of the exposure triangle. Please pardon my terrible penmanship, but I thought it was nicer than stealing someone else’s graphic, and faster than fumbling with Illustrator (not my forté)–

iso

All three of these settings can usually be controlled manually on most modern digital cameras, even inexpensive ones. This allows the photographer to take total control of the way that the image is exposed. There are several sought after effects that can be achieved by manually dictating the way that your camera exposes the image. First, the very basics–

ISO

Historically, ISO was a number that was used to measure the sensitivity of the emulsion on film. The lower the number, the slower that the emulsion reacted to light, making it take longer for the film to expose. This same idea translates to digital cameras. The ISO setting on a digital camera controls the sensitivity of the chip. The settings generally range from ISOs 100 to 3200 (or more), depending on what kind of camera you are using. The lower the number, the less sensitive the chip will be, and the longer it will take to achieve desired exposure. Conversely, when using a high ISO  number the chip will be very sensitive.

There is another factor that should be taken into account when selecting ISO. The lower the number, the richer and creamier (term of art, hahaha) the image will be. The higher the ISO, the grainier the image will become. The graininess that occurs at high ISO settings is commonly referred to as “noise.” Some times images are shot to purposely include noise for aesthetic effect (our friend Kat in Charleston, last summer) . Most of the time it is not desirable, because it can muddle the sharpness of the image.

As a rule of thumb, I try to keep the ISO at 400 or lower. But depending on lighting, that’s not always possible.

Shutter Speed

Shutter speed is pretty obvious, right? It is the setting that determines how long the shutter is open, allowing the film or chip to be exposed to the light. Fast shutter speeds are great for freezing time (fashion week fall 2010), like when shooting sports or if you are shooting outside on a really bright day. Slow shutter speeds are cool for showing motion (a great example, shot by my good friend Zach Tolbert), or for when shooting in low light. Shutter speed settings can range anywhere from 30″ to 1/2500″ (or more). In layman’s terms, those numbers translate to thirty seconds (a super slow speed, for shooting at night or something), to one twenty-five hundredth of a second.

About 90 percent of the time, I find myself shooting between 1/80″ and 1/640″. Many times, this setting will show up on the camera menu display as a single number, not a fraction. For example 1/80″ will just be 80. Higher end cameras will also generally have a “bulb” setting. Bulb will keep the shutter open as long as the shutter release button is pressed down (or press once to open, press again to close). The “bulb” setting is what people use to get those crazy long exposures of stuff like the stars swirling in the sky, etc..

Something to keep in mind– To obtain sharp images, it is best to keep the camera perfectly still while the shutter is open. So, shutter speeds slower than 1/80th of a second while shooting hand-held (not on a tripod) might run the risk of blurriness caused by camera shake, especially when large amounts of caffeine have been ingested.

Aperture

The aperture is the diaphragm behind the lens, that can be adjusted to control the flow of light coming through the lens. The size of the opening is measured in “f-stops” and is generally expressed as a fraction, because… that is what it is. An example of how f-stops are written is “f/4” or “f:4”. The “f” part of the fraction is referring to the focal length of the lens (we will get more into that later). So for example, if I’m using a 50mm lens, then “f” is 50. If I’m using a 50mm lens set to f/4, then I know that the aperture size is 1/4 of 50 millimeters.

Ok, if all of that sounds a little too much like math class, then just remember that the lower the f-stop, the larger the aperture is, and the more light you are letting through. So f/1.4 is letting in a lot of light. F/22 is only letting in a little pinhole of light. As with shutter speed, the f-stop may appear as a single number (not a fraction) on the camera menu. So, f/4 might just show up as “4” or “4.0.” A helpful way to think of it might be to remember that the higher the f-stop number the more light you are stop-ping from getting to the sensor.

One important thing to keep in mind when choosing the appropriate f-stop, is that the aperture size also affects the depth of field. Depth of field is what determines how much of your image will be in focus. We will discuss this more later. For now, just try to remember that it is affected by aperture (or f-stop).

For those who are more visual learners (like myself), I’ll use an example that one of my grade school photography teachers used, and has stuck with me all of these years. Again, please pardon my less than stellar drawing skills and penmanship–

bucket

Ok, in the amazing graphic above, we are using the metaphor of filling a bucket with water, as getting the correct exposure of an image. Just like the exposure triangle, we have three main variables. How large is the bucket? Compare the bucket size to the ISO setting. If the bucket is small (if the ISO is a high number), the bucket will fill up fast. Conversely, if the bucket is large (if the ISO is a low number) the bucket will take longer to fill.

Shutter speed can be compared to how long we have the tap open for.

Finally, compare the aperture to how large of a hose we are using. If we are using a fire hose (large aperture), the bucket will fill up much faster than if we are using a garden hose (small aperture).

The object is to use the exposure variables to offset each other, when we are seeking a certain result. Let’s say that we want to shoot with the aperture wide open to create a really shallow depth of field (more about that later). But since we are letting all of that light in, we are going to seriously overexpose the image, unless we compensate by choosing a fast shutter speed and/or drop the ISO.

Now let’s say that we are trying to shoot a hummingbird and freeze it’s wings motionless in the image. So, we need to use a really fast shutter speed. Unless we have a really bright light source, we are probably going to underexpose the image if we fail to boost the ISO and/or open up the aperture.

Hopefully some of this makes sense. I’m sure that there are plenty of other photographers who have helpful insight on understanding exposure. So, please feel free to contribute in the comments.

Should I be giving assignments?

on cameras and photography

jakes5d

Sometimes people email me asking for recommendations about purchasing a camera. I don’t mind it at all. I love cameras. I love talking about cameras, taking photos, and all of that stuff. But, I wish that people would be generally mindful of a few things when considering upgrading cameras, getting into photography, etc.. At least, I wish that they would be mindful if they are going to interact with me on the subject. I think that it would be less frustrating for all parties involved. For example– even though I know it is not meant to be offensive, I can’t help but be a little bit insulted when someone says something like “I want to get a good camera so my images will look like yours.” To me this is the equivalent of saying something like “This is really good food. I wish I could get a new kitchen, so that my cooking would taste like this.” I’m flattered that someone finds my images appealing, but discouraged by the insinuation that the camera did all of the work. I mean, having a nice camera definitely helps people produce quality images. But, it would be nice if people could acknowledge that there is a little more to it than just knowing how to use the shutter release button. I’m not trying to get all swollen headed, or pretend like I’m some sort of photography mogul. And I really hope that people don’t take this post the wrong way. I truly believe that, as with any artistic medium, producing something great comes from more than just having the right tools for the job. I think that in addition to having the right tools, a person should have a little bit of natural ability (which I think most people have), and willingness to study and practice.

At the risk of coming off like I think I know everything (I’m stating for the record, right now, that I don’t even come close to knowing everything about photography or anything else), I have decided to write a short series, in an attempt to possibly help people who are interested and want to become more involved in photography, and don’t mind the superfluous use of commas. In the series I will give my opinion about where to focus energy in order to improve ones photography skills, and possibly throw in some basic knowledge and links to some online resources that I find helpful. Intend to cover things like basic composition, exposure, lighting, and how to choose a camera. Again, all just my opinion, in hopes that someone finds it helpful. The “dropping knowledge” tag is meant to be tongue in cheek.

i want this– papercraft leica m3 pinhole camera

leica3

I remember taking my first photography class, in like 7th or 8th grade. One of the very first projects that we did was make pinhole cameras. We spent one day making the cameras (out of shoe boxes), then the next day wandering around campus during the entire period capturing images with them. We were exposing directly to photo paper, so everything was a negative. But I still remember how much fun it was.

Enter the paper Leica m3. How awesome is this? I would say that it is quite an upgrade from the rickety shoebox contraption that I built back in the day. This printable papercraft Leica m3 was designed by Matthew Nicholson, and is available for download from his site for only £1.50. It comes with assembly instructions (which appear to indicate that it shoots 220 medium format film [same as the Holga]). I think that I may have found a project for the weekend. A few more looks below–

One WTC as of yesterday.

2011-shotbyjake-com-0184

Every once in a while I feel the need to write about the World Trade Center construction progress. Here is my 2008 rant about calling it ground zero (which people still do, btw). Here is a shot of One World Trade Center last November. And the shot above is one that I snapped yesterday from ground level. It’s pretty crazy that next month will mark 10 years since the attacks. That means that next August I will have been in NY for 10 years. My, how time flies.

I want this: NOKTOR 50mm f/.95

03

I was browsing Hypebeast today, when I came across this gem. Made by NOKTOR, this 50mm prime opens up to f/.95. Yes, that means that the aperture actually goes larger than the focal length. Pretty amazing. They are billing is as a “HyperPrime.” The lens can be ordered on the NOKTOR site, and ships starting July 31. The price is about $8,400 in Hong Kong dollars (from where the units ship). But that is only about $1100 USD. So, it is actually less expensive than the Canon 50mm f/1.2L. I would be curious to know how the NOKTOR glass stacks up against the Canon L optics. There is one huuuuuugggggeeeee drawback from my perspective, though. Besides not having AF, this lens only comes in MFT and E-mount. Which means that I would have to get an adapter to shoot with this on a Canon body. Hopefully they will remedy that issue by the time I actually get serious about purchasing one.
