I have not yet tried scanning the negatives, although I was thinking about it yesterday as I was sorting through some of them. I can scan the 35 mm negatives with my current scanner, but will need a new scanner for the 120 and larger negs.
I will probably try a few just for fun, but for me personally I enjoy the challenge of the dark room, and at least so far it's much easier for me to burn in and hold back parts of the image in the darkroom than on the computer. Which is something I'll probably eventually figure out in Photoshop.
It isn't a quality issue. I have seen some gangbusters B&W prints done by computer. At last year's Long Steel Rails Festival at Ely we had a photographer selling some wonderful B&W prints that he regularly does by scanning his negatives. One advantage of the computer is once you have the image the way you want it, you can replicated it easily....whereas each darkroom print is something of an adventure, at least for me.
