My somewhat foggy crystal ball sees traditional silver based photography becoming more of an alternative process practiced by fewer people than today. I will be one of those.
I recently watched a video about Keith Carter, part of which had him talking about his doing a series of portraits of his mother when she was in the final stages of her life when she really didn't know who he was and how important that process was for both him and his siblings. It got me to thinking about my almost 95 year-old Godmother for whom my wife and I have important care giving responsibilities.
You might enjoy the video. Here is a utube snippit. http://www.youtube.com/watch?v=J4vm5P8-N0o
