In a photographic copying apparatus for processing exposed photographic film there are recorded in a measuring station, in addition to measurement data relating to the colour composition of the negative, also splice events and perforation events and their occurrence on the film. The recorded data are fed to a calculating and evaluation unit and there stored in the form of a table (event table). The occurrence of splice events and perforation events on the film is recorded in one or more repositioning processing stations. Those data are stored in the calculating and evaluation unit in the form of a table (positi on table). In order to reposition the film in each processing station, the tables are correlated and any deviations established are taken into account when the film is repositioned. In order to detect the perforation and splice events, the measuring station (7) and the processing stations (8, 9) are equipped with perforation- and splice-detectors (72, 73 and 82, 83 and 92, 93, respectively).
