Chapter 3: Scanning Film

Scanned images cannot turn out better than the original film which was scanned. Every defect on the film will be recorded by the scanner as an image detail. It can be frustrating to start with an image that appears satisfactory as a 4" × 6" print, only to find noticeable image defects when the same image is
viewed on the monitor.

One must check whether such defects are caused by the scan or originate from the film. Quite often a poor original is to blame. If an image is scanned at 4000 dpi and viewed at full size, even the smallest defects become visible. The film should be checked with a good loupe. In many cases the film is fine, but the scanner is poorly focused. Even the best scanning method cannot compensate for a blurry original on film.
