Making a Fade-Out by after Treatment
Fade-outs have been made for many years by moving the diaphragm or using a dissolving shutter in the camera during exposure. It is more convenient, however, to make a fade on either the developed positive or negative film by chemical means. — A modified Belitzski reducer formula of the “cutting” type is recommended for negative fade-outs. The film is introduced into a tube or tank filled with the solution with a positive acceleration so that the portion immersed last receives the least degree of reduction and a wedge effect is obtained. Another method consists in bleaching out the image in either a ferricyanide-bromide or a permanganate bleaching bath and redeveloping with the same manipulative treatment as for reduction. Positive fade-outs may be made conveniently by tinting with a black dye solution. — A mechanical device is described by means of which the necessary acceleration may be imparted to the film when immersing in the various solutions.
