<p>Method of improving the colour balance of a multicolour reversal image obtained in a photographic material itself or obtained by a diffusion transfer reversal process in an image receiving material is provided, wherein said method comprises, as illustrated in Fig. 3, the steps of:
(1) providing a photographic silver halide material (4) capable of yielding in said material or in an image receiving layer a multi- colour reversal image of average gradient of at least 1.8;(2) image-wise exposing said photographic material to or through a multi-colour continuous tone original (2) while keeping in the optical path between the original and the photographic material a light-distribution means (3) dividing the light in line-like or dot-like portions over the exposed area of the photographic material,(3) developing and reversal-processing said photographic material, e.g. by dye diffusion transfer-processing, hereby producing a reversal image with average gradient of at most 1.50 and reduced colour point spreading.</p> |
