It is understood that optics is the science that studies the production, 14 propagation, interaction and detection of light. Regarding the detection there are some materials 15 sensitive to light (photosensitive) that are used like photomultipliers, CCD’s, crystals, two 16 dimension (2D) materials and more. Among the 2D materials the most popular through several 17 centuries has been gelatin based photographic emulsion that records spatial distributions of light. 18 More recently (1970) films made of Gelatin with Dichromate (DCG) and dyes have been used. We 19 describe some characteristics and applications of these two photosensitive materials.
