A study was made into the effect of the secondary "low Intensity” latensification on Super Panchro Press, Type 8 film. The response variables tested for were speed, D-Max, gamma, and fog. Tests were conducted to appraise the effect of Daylight and Tungsten illumination for Exposure and Latensification and their interaction. The experiment revealed that a significant speed increase is possible; gamma is affected by Latensification time and illumination; D-Max is affected by illumination; and that the degree of latensification is dependent upon the time of secondary exposure. It was found that a significant latensification effect can be achieved with a small fog level increase.
