Photosensitive materials (x-ray films) are used to record the invisible x-ray image. It is required to reproduce all the characteristics of the invisible image in visible form .The films ability to do so depends on its sensitometric properties. Sensitometer: Measures films sensitivity to light; shows the range of densities on an image. Sensitometry:- The scientific study of the response of photosensitive material to different levels of exposure. How is it done? Producing a sensitometric strip
