Some chemical compounds can be used in the chemical photographic development process of silver halide panchromatic motion picture materials to decrease their sensitivity upon exposure whereby their development is possible at relatively bright illumination. Such compounds can be the organic compounds of o-elements with complanar structure. It was observed, in particular, the pronounced desensitizing effect of bis (thiosemicarbazido) palladium (Ⅱ) dichloride of the formula:
