Agfacolor Ultra Film
Description
“Agfacolor Ultra Film (1934–1941): individual colored grains cannot be seen with the naked eye, but clumps of grains of the same color give the image a pointillist effect (Fig. 2.72). There is no black pigment filler. The film has a thick base that tends to curl toward the emulsion side.”
