Looking for help....i have a large number of photos and some slides to scan. I have a V500 Epson scanner acquired a few years ago. First question is, is it up to the job....I notice there are now many other newer models. If it is, what are the best settings. For photos it seems around 600dpi gives an ok result, 1200dpi takes a bit longer. For 35mm slides, 1200dpi seemed right and at least you can do 4 slides together. Is Full Auto mode as good as the Professional mode.....it didnt seem much different with ICE turned on. Any tips or comments appreciated. Also is there any way to clean old slides, other than a soft brush to remove dust. Finger marks???
