Scala 200x Information on the performance characteristics of Agfa Professional films Sensitivity speed Sensitivity is a measure of the response of a film to light exposure The speed of films is based on the minimum exposure required for producing optimum tone reproduction It is determined according to international standards for b amp w colour negative and colour reversal films that specify the exposure chemical processing and densitometer The figure given on the pack applies however to the exposure time range of 1 s to 1 10 000 s Absolutely no sensitivity devia tions occur with any Agfa films within this range Reciprocity effect The effect of an exposure of silver halide based films to light is the product of light intensity x time of exposure i e E Lx T This reciprocity law first defined by Bunsen and Roscoe and also known as the Schwarzschild effect holds that a 1 100 second exposure time at a light intensity of 1 lux will yield the same results as an exposure time of 1 second at 100 lux However at intensities significantly below or above the range in which reci procity is maintained with a given film more exposure will be required to achieve the same result This is known as reciprocity failure With colour films the failure of reciprocity tends to be different for the blue green and or red recording layers resulting in a shift in colour and colour contrast balance Appropriate information about reciprocity fa
