Well, that is far more in line of what I'd expect. I think that is an acceptable quality. Now the question is reduced to would I pay that price for it? I recently did some Provia 100 slide film with the V700 and the result is about the same. But the work involved is a lot more. Just getting the dust off, putting the film in the holder, making sure it is flat etc makes this a very unrewarding experience. Certainly if you compare this to the same slide projected. So yes, I could see it as an alternative to home scanning.
I can see why you did the changes to the raw scan now. Probably not what I would do, but that is a matter of taste.
