This challenge seemed ripe for focus stacking, so here's a 20 shot stack of a peanut butter and chocolate cookie I made (I made the cookie and the focus stack). I actually made a batch of these cookies on Thursday, and when I realized that we only had four left today, I thought I'd better get this shot quickly, before my wife ate the rest. :) (OK, OK, I eat as many as she does, which is a lot, but we both run, so we earn it).
