I haven’t been impressed with the exposure triangle diagrams I’ve seen on the Web so I decided to make my own. Then after working on it for a while I realized that though there are 3 variables, they’re not directly related in a “triangle” so the whole exposure triangle concept is misleading. With input from a couple other photographers I eventually came up with a diagram I think is much better. I like to think of it as a whole chapter on basic exposure crammed into one picture.
