As part of the process, I am going through negatives from long ago, when I had a B&W darkroom and shot and processed an amazing number of pictures. It's like time travel; I look at those people and I remember them (mostly), but they're so young - so appallingly young! And the details I notice - details about the rooms we lived in, the clothes we wore, the casual gestures and expressions - these bring back so many memories. Some of the people are gone now, but here they are, frozen for a moment to live, piecewise, again. Some of these photos and the memories they bring back are almost more than I can stand.
So this is a plea of sorts: save photos of those near and dear to you! Save them in the most long-lasting, safest means you can. That's probably on your hard drive or maybe on CD/DVD's. Then, someday, you and those who follow you will be able to revisit these friends and loved ones, and you will thank me for this advice.
