Digital photographs are easy to accumulate in vast numbers. Some photographers recommend deleting anything that isn't perfect - as soon as possible, preferably before it leaves the camera. I don't subscribe to that philosophy and keep everything I shoot unless its absolutely awful.
I have a folder structure that allows good stuff to 'bubble' to the surface while all the raw material (usually RAW material) sits in a series of basement folders called 'Originals'. When I need to try out some new software or attempt a new processing approach I dig into my 'Originals' folders to find something to practice on. Case in point is the picture below - what I wanted to try didn't work out but, in the process, I discovered the original reason I took the shot - the light - buried beneath a rather dull and uninteresting set of RAW files.
So, tonight I feel vindicated and confirmed in my old hoarder ways :-)
