Abstract

A mark is recorded on the colour negative film to identify the colour temp. of the light source during exposure and colour correction is carried out on the basic of this mark during the reprodn. stage. Pref. the mark is made by equipment fitted with 2 or more photocells, pref. selectively sensitive to different regions of the spectrum. Correct colour correction is possible, so that high quality can be made, regardless of the light source used for exposure. Pref. the mark is made when the output from one photocell exceeds that from another by a certain margin. The output from the photocells is used to activate light-emitting equipment, pref. LEDs, giving light which records a mark on the edge of the individual image of the negative film, when the margin is exceeded. The photocells are based on CdS, esp. red-sensitive CdSSe and blue- or green-sensitive CdSZn. It is pref. to use 3 photocells and 2 LEDs.
