Epson V850 work-around for scanning 5x7 negatives.

[Oren Grad]

Then, put Anti-Newton Ring glass on top (mat side down on to top of negative) to hold the negative flat.

I get artifacts in my V700 scans when I have AN glass on top of the negative, I think generated by reflections from the extra glass surface. Often my film stays flat even without; otherwise the negative needs to be held down some other way.

I may try again at some point with antireflection coated glass. It's a pain to find large pieces without subtle flaws, but perhaps that will matter less when the glass is being used to hold down a negative for scanning than it does in a negative carrier or in contact printing.
