Solution and method for processing high speed video news film

A high speed color reversal cine film with latent images recorded thereon is so processed as to color-develop the latent images and concurrently reduce the high contrast at the dark end of the tone scale which is inherent in the prior art development of such film. The new method utilizes in the colo...

description	A high speed color reversal cine film with latent images recorded thereon is so processed as to color-develop the latent images and concurrently reduce the high contrast at the dark end of the tone scale which is inherent in the prior art development of such film. The new method utilizes in the color developer bath increased amounts (in comparison with prior art color developer baths) of a competing coupler such as citrazinic acid and of a silver halide solvent such as ethylene diamine and reduces the amount of a reversal agent such as t-butylamine borane, and also includes a competing non-coupling developer such as 4-hydroxymethyl-4-methyl-1-phenyl-3-pyrazolidone, or phenidone, or a derivative thereof.
