CHAPTER 3 FUNDAMENTALS OF PHOTOGRAPHY AND CINEMATOGRAPHY Incident light meters can be considered true exposure meters because they are unaffected by directional light sources in a scene. Incident light meters cannot be used to individually “sample” the tones present in a scene. These meters can read only the light falling on a scene. Therefore, these types of light meters must be pointed in the direction of incoming light rather than reading the light reflected off the subject. Incident light meters are mostly handheld light meters with white diffusers.

Light always interacts in the presence of suitable media. Light passing through film is no exception. It goes from the air to the plastic and then to the silver halide emulsion and then to the film’s antireflective coatings and out the other side. 1. Light passing though the film’s emulsion creates a primary image by directly interacting with the silver halides; in some areas, it passes directly through the film. In areas where it interacted with the silver halides, the light is reflected indirectly around the film, creating irradiation.

This after-image follows wherever we point our eyes. But if we push the skin around the sides of our eyes with our fingers, the after-image does not move. This phenomenon is unlike regular visual stimuli, which move in the opposite direction from the one in which the eye is pushed. This difference demonstrates that the retinal image motion detection system is independent of the eye-head system and that the eye muscles are not responsible for signaling to the visual system to cancel the retinal image when detecting motion.
