I agree with msbarnes: scanning allowed me to get into analogue photography when I otherwise wouldn't have been able to. Without appropriate space for a darkroom, I had the choice to keep using my DSLR as my sole camera, rededicate a large part of my apartment to a hobby I wasn't at that time sure I'd stick with, or scan the negatives.

I'm ever so glad I decided to scan: especially since improving scan technology means that digital images' resolution is fixed when the photograph is taken, but my photos keep getting better and better resolution as time goes by.
