The Exposure Triangle: Bringing it All Together

Location: India
Camera info: Canon Rebel 350 D • lens 18-55mm f/3.5-5.6
ISO 800 • f 20 • 1/125 sec

Hey my fellow shutter-bugs! It’s been a while since I had a lesson, so I owe you one – and it’s just in time for you to take all those crazy family pictures during Christmas! Previously, I talked about Aperture and Shutter Speed. Today’s lesson is on ISO, as well as answering the question: so what’s the point of all of this?

ISO (International Standards Organization), or as old-school photographers would say, Film Speed, is simply a measurement of how quickly the media in your camera can pick up light. For example, think about the last time you moved. If you had to pack a truck, how long would it take to fill if only you were working? How long would it take if you had a whole team of movers? These scenarios would represent low and high ISO settings, respectively. Higher ISOs “pack in” light faster than low ones, allowing you to shoot better pictures in low light. They also introduce film grain (pixellation) at higher levels depending on your camera.

So now you have all three pieces of the Exposure Triangle, every photographer’s rule to taking properly exposed pictures. The main point is to keep the triangle balanced. When you adjust shutter speed down, you may need to open your aperture or use a higher ISO. When you set a high ISO to shoot at night, you will need a longer shutter speed or wide aperture, etc. You will know these three are balanced when your camera’s light meter is centered.

Now comes the fun part: with this knowlege, you can shoot any camera in manual mode and actually know what you’re doing! 😀 You can try several combinations of the three elements, just remember how else they affect your photos (aperture affects depth of focus, shutter speed affects blur, and ISO affects noise). Also, you can use the Tv, Av, P, and any other settings appropriately. Just know that Tv lets you choose your shutter speed & ISO, and it will pick the aperture for you. Likewise, Av does the same with letting you control aperture. P is fully automatic except for the focus & flash.

Ok, your turn! Try taking some pictures and let us know your experience in the comments. Did you get the image you were going for? Do you know why/why not?


Making Subjects Stand Out: Composition 2

Location: Thailand
Camera info: Canon Rebel 350D • lens 18-55mm f/3.5-5.6
ISO 1600 • f 7.1 • 1/160 sec

Hey all you photo enthusiasts! It’s a bonus photo lesson this month! Aren’t you excited?!?!? Previously, I shared about the Rule of Thirds and Framing. This week I would like to extend the lesson to Leading Lines, Active Space, and Simplicity.

Leading Lines are simply the way you use elements in the picture to draw people’s eyes to your subject. In my featured photo this week, notice how the tiger’s paw draws your eyes up to his face, then across to mine and my friend’s. Many people use roads, rivers, streams, bridges, branches, or fences as their lines. Anything can work! Straight, curved, or parallel lines are all good at promoting interest, and you can work them in horizontally, vertically, or diagonally.

Active Space is used when your subject is moving or looking off to one side of the frame. Most people’s minds automatically wonder what they are running toward or looking at. Therefore, the most effective photography often will leave extra space off that side of the photo, even if it’s just open field.

Simplicity is probably the easiest concept to understand, but can be difficult to photograph. The premise is: don’t put a bunch of stuff in your background that can distract you from the main subject. Sometimes this is done by the angle you take your shot, sometimes it is accomplished through creative use of aperture. A camera will flatten a 3D image down into a 2D photo, so things far behind your subject can instead look like they’re growing out of their heads, if you don’t pay attention. Remember: nothing should be in your photo that isn’t there on purpose.

Setting Up the Perfect Scene: Composition 1

Location: Indonesia
Camera info: Fuji Finepix A303 / Automatic Point & Shoot
ISO 100 • f 7 • 1/340 sec

For all the other aspiring photographers out there, here’s one you don’t want to miss! Previously, I talked about the use of aperture and timing. This week’s photo lesson covers a few points of composition, something you can practice with anything from a DSLR to a cell phone camera. There are lots of rules to composition, yet rules were made to be broken! My suggestion is to learn the rules and practice them until you know when you can break them. Since there are so many, I’ll give a few here and plan to add more in future posts.

The most well-known composition rule is the “Rule of Thirds.” Take any scene, and divide it up into three pieces, both horozontally and vertically. Now place your subject at any point where those lines meet (which normally seems just off-center). Here is an example (this can also be applied vertically). One time to break this rule: when your scene is symmetrical.

The second rule: framing. My photo above is the example for this one. Putting elements on the edges of the picture can help draw the viewer’s eye to your subject of the photo. In this case, I took this photo of a dock in Indonesia from inside the outhouse next door (and yes, it’s kinda freaky that the holes in the boards were that big!). Trees also make good frames.

So start practicing with these two rules and there will be more to come!
