I've been thinking about this for the last week or so. I frequently "live" with negatives for up to a year until I print them. Along with contact sheets I also scan all my negatives and frequently view them on the computer screen. As time goes by certain photographs stay great and others I lose interest in. This helps me to thin out the keepers. I'll then begin to think of how I want to create a final print.
Recently though I've been printing negatives taken within the past month. I like working this way, the photograph is still fresh in my mind. Also the negative is new and clean and more free of dust than a negative that's been in storage for a year or so. The downside of this approach though is that I may end up spending hours on prints of negatives that I'm excited about now but may not hold my attention months and years down the road.
Thoughts? What's your approach?
