Originally posted by Venturi I really think, based on your stated intents, that the anti-newton glass from betterscanning is going to be your wisest investment if you're doing negatives.
What I meant by "serious archiving" was more along the lines of professional/museum/gallery work - not that archiving 30+ years of photos is in any way trivial. I am embarking on a rather serious project of archiving all of my dad's slides and negatives from his post-WWII work travels through the south pacific and east asia. I get nervous just opening those old metal negative canisters.
Another vote for Betterscanning.com products. I have a V700 and the stock carriers for 120 are totally inadequate, the film sags so you can't get uniform sharpness. Their MF holder and anti-Newton's glass - and some fiddley adjustments to the height of the carrier, and wonderful results.
The 700's 35mm carriers are okay, but I think I should get the anti - glass for film bowed across its width. I've heard good things about Vuescan software, BTW. They have a trial version available.
