The colours on a scanned photograph were different (darker) to those obtained by scanning into my usual image processing software.

Quite possibly, there may be need for adjustment to suit your printer as well! Neville Dean ---------------------------- Anglia Polytechnic University Cambridge England c.n.dean@anglia.ac.uk
