| Abstract: | Exposure and its response to photographic emulsion is discussed. The paper further describes exposure, its contents, intensity and time (i and t), effects of low and high i and t, Reciprocity law Failure (R. L. F.), intermittent exposures, solarisation, Clayden and Herschel effect, and hypersensitizing through neutral density filter and long time development. Through these processes mentioned already, print of low contrast and high definition as compared with the normal print from the same negative has been achieved. |
