I want to scan 35mm slides and print them as an 11x14 photo. I am using an Epson Perfection V600 Photo scanner in Professional Mode and scanned a single slide twice, once with the target size set to 'original' and again with the target size set to 11x14. I printed both versions as 11x14 but neither produced good results, both were pixelated. What target size should I use, and what other parameters do I need to set? Thank you.
