Consider this photo:
Camera Settings - 1/160th. sec. shutter speed, f/5.6, ISO 400, at 50mm.
It took me almost a couple of years to decide on whether or not I should post this online, since personally, I saw too many "things" I don't normally like in a shot. Sure, there's the rumpled curtain, the leg of a lightstand at the lower left corner, and the comb underneath Jazz's legs (which I easily took out via photoshop). But I overlooked these things simply because my eyes were pulled to her almost silhouetted body, a stark contrast to the highly exposed background. What made this photo stay for a few days in my archives was actually something more technical than that: her face wasn't properly in focus, and this gave me a lot of trouble. Yes, believe me. I can be stopped at times with little hiccups like this, only to realize that I can only see the flaw when I'm looking at it at a 150% crop.
How many of us have stories similar to this? How many of us would set aside beautiful photos simply because there is something trivially wrong with it that, chances are, only the photographer him/herself can find it?
My message here is pretty much simple and straightforward: think twice about your "bad" photos before sending them to the trash/recycle bin. They may not be as bad as you would originally think they are, and that you might have an actual use for them someday.
