Being new to photography I'm trying to find order in some things I do, like the post production work flow, and specifically what to keep and what to trash. How do you guys determine this? I obviously trash anything that is just flat out horrible composition or is blurry. But what about underexposed and overexposed shots? I know those can be fixed in PP. There are times when I'll take 30 shots of the same thing and have a good set of exposures. At that point I can't decide to keep the over/underexposed shots around for possible future use or if I'm just cluttering my catalog. Any insight you guys can provide would be much appreciated. I know a lot of it probably comes down to personal preference or how much you're willing to spend on hard drive space.
