How do I decide which resolution to select when scanning from Epson Scan 2?

• The software recommends a resolution when you select one of the following Scan Settings: Film, Document, Magazine, Newspaper, or Photo. If you plan to enlarge a negative or slide for printing, see the table below.

  Print size from 35mm film	DPI required
  4 x 6 inches	1200 dpi
  5 x 7 inches	1600 dpi
  8 x 10 inches	2400 dpi
  11 x 17 inches	3200 dpi
  13 x 19 inches	4800 dpi
  17 x 22 inches	6400 dpi

  Note: Scanner resolution is a measurement of enlargement power, not image quality. A resolution of 300 dpi produces a file that can be printed at the same size as the original. Doubling (600 dpi) or quadrupling (1200 dpi) the resolution increases the output size accordingly. The larger the original, the lower the resolution needs to be; smaller items, such as 35mm film, require a higher resolution for common printing sizes. Higher resolutions result in larger files and longer scan or print times.
