Now, before we take a look at specific images of good exposure and bad exposure, let's just take a quick minute and look at exactly what kind of information is available by looking at the histogram. Now, the way it stands right here, we have what's known as the expanded view. It's a larger view of the histogram and we can actually get more information if we ask for the statistics of the histogram and this brings up a mountain of mathematics that I have no idea what this means. If you do, more power to you. I never use the stuff, but it's there if you really, really want it. The other thing you can do is do what's known as an all-channels view and that takes each of the color sections of the RGB spectrum and breaks them down individually. You can see the brightness of the red channel, brightness of the green channel and the brightness of the blue channel. In this particular instance, this is a very, very balanced exposure so everything looks exactly the way it should be. This is about the best example of balanced exposure that you're going to see. So that's what the histogram can do for you. It gives you all kinds of information if you want it. Now, let's take a look at specific images and get a feel for what a good exposure and a bad exposure looks like as represented in the histogram.
