I’m taking on a project of scanning 50 years of family photos. I’ve tested my scanner (Epson V700), every think is working, positives, negative, and photos. I’ve tried to enlarge a 35mm negative and the 5X7 print is really grainy. Any ideas for the settings, I using the plastic film strip holder and some how the Espon scanner know how many prints I’m scaning. What about resolution more then 300ppi and I need to restudy 16bit vs 24 bit etc . Any help will be appreciated!!!
