Yep. I was always amazed at how bad an 8x10 enlargement could look from a "perfectly good" negative that looked great at 3x5 ...

I have all of my Dad's old slides and prints. All taken with Brownie Starflashes and Instamatics. Having a good scanner is key, and then they take some post processing. (Sorry APUG) I have more problems with color fading than sharpness, however. Perhaps because I have low expectations on the sharpness.
