Method and materials for improving the colour balance of photographic multicolour images. A process for the production of a multicolour reversal image with improved colour balance is provided which process comprises the steps of directing incident image light dot- or linewise modulated by a light-distributing means onto a multicolour photographic silver halide emulsion material containing a blue-, a green- and a red-sensitive silver halide emulsion layer and processing said silver halide emulsion layers to form a colour reversal image. In the maximum density part of the dots or lines of said light distributing means e.g. a contact screen the ratio of the absorption density for the light corresponding with the spectral sensitivity region of the silver halide emulsion layer being during the exposure most remote from the light-distributing means to the absorption density for the light of the whole visible spectrum (400 - 700 nm) is higher than the said ratio in any other density part of the dots or lines (see Figure 1).
