As I am pondering whether going to total digital, I remembered my portable disk full of scanned photos from the last few years. It is a great fun digging out those photos and remembered the day and night spent in extreme weather sometime trying to get a good photo.
I would still take photos film or digital, but when I am at home I could always work on these saved photos. This is like savings in a bank. The only difference is that you always make deposits and the benefit is longer term, and the pool is always growing bigger. Apart from bringing back good old memories, they could bring some financial return in the long run.
