Fred Picker strongly recommended throwing away all of your not very good images at least once a year. The rationale was that it was better to keep moving forward to make better images than to get caught up in trying to make a bad image better. I am horrified by the tendency of digital photographers to keep adding hard drives to archive an unlimited number of crappy images, but now that I am back to 4x5 the same issue is coming up. For example, I have a lot of images that did not work - not quite enough shadow detail, the wind came up, I forgot to untilt the lens, etc. Out of the first 100 sheets of doing this after a long absence, I probably have 3 that I think are good enough to keep and keep working on printing. My inclination is to toss the rest and not look back, but I am curious what others do.
