What ppi should I use for scanning 35mm slides on my flat bed scanner?
A. The best approach is to follow the procedure presented in the FAQ above that is titled: I make many scans of photos (prints and slides). They look good on the screen but bad when I print them. What am I doing wrong? But if thats too much arithmetic then go for either of these simpler approaches. 1. Some scanners can do the arithmetic for you if you tell them the size of the input (the slide in this case) and the size of your intended print (say 5″x 7″). You will probably have to read the scanner manual to find out if yours is this helpful. 2. Decide what maximum print size you intend to use and the type printer you are aiming for and read ppi from the following table.
