Chromium Intensifier

Formulary's Chromium Intensifer For Negatives increases the density of black and white negatives. This is a proportional intensifier. The amount of intensification is somewhat proportional to the amount of silver originally present in the negative. Negatives intensified with chromium are stable. The process is used in room light and must be redeveloped in a quick-acting print developer. Chemicals are used once and discarded. Additional intensification may be obtained by repeating the process. Not for T-grain emulsions (see Silver Intensifier).
