Yes,and sometimes I find that I have spent too much time on one image when I have many others that are just as good or maybe even better. And then I keep making new images but don't have enough time to carefully work with them. Still I'm grateful that I have a steady job which makes opening my lightroom catalog even more special as an escape to my world of photography. Yes Rob, I do not have a professional purpose which surely will send me into a tailspin of indecision and eventual insanity. Still I have many more collections that I want to create if for nothing else, myself. I couldn't agree more with having a defined purpose. I don't want to spend endless hours on choosing images, when I need time to get them post processed for printing.
I still feel that way, so even when devoid of client, the way out has been to shoot only one idea at a time - maybe three or so variations on exposure around the one given by Matrix, and close down. On to the next. Back at the ranch, I pop them all into Nikon's Capture NX2 and pick the one that closest resembles a decent tranny, look at the thing's readings and check exposure and colour temp, and then save it as TIFF to Photoshop as quickly as possible. Once there, I swap to native PS files and scrub the TIFF.
I can't remember going back to anything left behind in Nikon Capture. I have to go with my hunch or go crazy. It's the same idea as scanning - pick the one you think best and forget the rest. Life and patience are both too short.
And it's not true that without a client nobody's paying: you are - with your time, and that's the most precious currency of them all...
