You've probably seen pictures in "Do It Yourself" books and magazines that detail a step-by-step process of how to do something. You may either take a single photograph or a series that could be used to illustrate part or all of a step-by-step procedure.
Multiple captures from different scenes can be used for the purpose of illustrating the steps. These captures should not be over-layed on top of each other to create composite images though. Text is allowed.
