A New Photographic Developer for Picture Negatives
A new developer formula is described which has the property of resisting the effect of bromide while maintaining good characteristics suitable for picture negatives. This developer may be replenished in the same manner as ordinary positive developers. By use of this formula the H and D characteristic is held essentially constant, and control is maintained over the effective emulsion speed of the developed film. As much as 100 per cent increase in emulsion speed may be obtained while maintaining gamma and grain structure comparable to normal commercial negative developers.
