I've started scanning in some of my old 35mm prints so I have all my pix in digital form. Been using my ScanSnap S1500 which does a decent enough job. My question is how others that have done this organized their scanned images. Some of the photos don't have dates on them so any it's just a guess as to when they were taken. Do you try to group them into coherent events and approximate a date? Any other tips? Some are just single pictures from an event in the past. I'm using Aperture for photo management.
