Join Ben Long for an in-depth discussion in this video Exposure compensation, part of Canon 60D Essential Training.
Exposure compensation is one of the most powerful exposure controls on your camera. As such, it may very well become one of the most often used controls on your camera. With it you can easily handle back lighting situations, you can control tonality, you can calm down overexposed highlights. To sum up, exposure compensation lets you adjust the camera's exposure up or down in fractional or whole stop increments. Exposure compensation is very easy to control on the 60D, but before I can add any, I need to meter.
So I am going to half-press the Shutter button, and there's my shutter speed and aperture right there. To apply any exposure compensation, all I do now is turn this dial. So if I rotate it to the right, I get positive exposure compensation. That is, my image will get brighter. I will add exposure, so now at the 60th at F5. And as I go to the left, I get negative exposure compensation. So this means no compensation of all; this is what the camera thinks is correct metering. As I go up, this is brighter and as I go left, this is darker.
The big stops there are full stops and the little stops in between are one-third stop increments. Now, notice as I'm dialing this around, it's changing both shutter speed and aperture. Now, it's trying to work in my favor. It's trying to make sure that it's keeping shutter speed at something that will be suitable for handheld shooting, but there are going to be times when it's got to change both. If I change ISO to Auto, then it's possibly going to change all three parameters, depending on what the lighting is like. It's not changing ISO here, because we have so much light.
But there might be times when I want to be sure that exposure compensation leaves one parameter alone, and for that I switch to a Priority mode. We will be talking about these in detail later, but when I am in Shutter Priority mode, that means that exposure compensation is never going to change shutter speed. In this case it's changing ISO, because I am in auto ISO, and it's making changes to aperture, but it's leaving shutter speed alone. The same thing happens in aperture priority. Now it won't touch aperture. It will only change shutter speed, or ISO, if I'm in Auto ISO mode.
It's important to note that the exposure compensation setting is sticky. That is, if you dial in one stop of overexposure, it will stay there until you dial it to something else or turn off the camera. So be careful when you dial in some exposure compensation, because you don't want to screw up any shots that you take after that. This can also be very handy because if you know that you will need to shoot a whole batch of images with a particular compensation, you can just dial it in and leave it there. Finally, if you would prefer the exposure compensation interval to be something other than one-third stopped, you can change that, as we'll see in Chapter 16.
