I'm not certain if this counts, but think I recently had the opposite of an "ah-ha" moment. More of a realization actually. Looking back at my last several rolls of film with many frames that are out of focus, or show camera movement, or non-flattering expressions on faces, and just bad timing, I think I should go back to shooting subjects that don't move. In fact, I was thinking about starting a thread with the title "Anyone else shoot pictures that suck?"
