1. Method for correcting at least one colour of a photographic image including at least one pattern area or image pattern with a predictably known colour (memory colour), said image being transferred to a digital representation, the method comprising the following steps:
- a) said at least one pattern area or image pattern is being detected with respect to its presence and its location, and preferably also with respect to its dimensions;
b) an existing colour in the at least one detected pattern area or image pattern being determined;
