ABSTRACT:
The invention relates to a process and an equipment for making color enlaments in additive method, where the device can be fitted onto the traditional enlargers. By using the solution according to the invention the arrangement of the additive color filters under the lens of the enlarger can be solved in a stable but not containing manner, simultaneously ensuring easy and alternating actuating and integration of the colors of the negative. By means of the comparative process, by using the color-analyzer mask and the properly dark colored reference standards belong to the equipment, the color and density balance of the prints to be enlarged can be adjusted by the way of one single trial development, independent of the individual subjective color perceptional ability.
