Agfacolor Ultra Plate
Description
“Agfacolor Ultra Plate (1936–1938): colored particles very small and not visible to the naked eye, but clumps of particles of the same color give the image a pointillist effect (Fig. 2.65). Unlike with the autochromes, in which the grains are remarkably uniform in size, great variation in the sizes of grains exists in Agfa screen plates. There is no black pigment filler between the colored grains; however, the overlapping of colored particles might form a dark edge around them, especially the red ones. Particles are less clumped than in early plates.”
