a friend of mine borrowed me his epson v700, as I wanted to try scanning some of my prints and transparecies. Till now I have only tried Epson scan software, and did not have any problem with "reflective" pictures. But when I tried scanning a 4x5 negative (without holder because my friend forgot it at home) it returned badly striped pictures, no matter what I chose as settings!
Knowing why my friend bought this scanner, probably he never tried scanning films, so he could be unaware of any problem! In any case these days it will be very difficult for me to get in touch with him... Please help!
I try to add an example. The stripes follow the direction towards which the lamp moves.
