This is an important concept in photography; it is not the first that is discussed in photography or cinematography courses, but it should be. Why? Because all light levels on a given scene are evaluated using some kind of a light meter. Light meters are devices that read the amount of illumination present in a given area. They are crucial tools in making successful photographs and capturing the light shining on scenes. There are two basic kinds of light meters: reflected light meters and incident light meters.

The areas where the object protected the silver compound from light remain less dark compared with the exposed areas. The problem with this method of “photography” is that gradually, the protected areas darken when exposed to ambient light. Numerous attempts in the early 1700s to make the exposed image permanent failed. It was not until 1839 that Sir John Herschel found that sodium hyposulphite can make the images permanent. He is also credited with inventing the word photography. ” Reading this appendix will help you understand the physical and chemical basis for the premier art form of the 20th century, which is cinema.

In the retina, rather than functioning as a simple off and on detector, a device tells what is happening in the neighboring cells to make sense of the signal as a whole. Without such a device, the retina would be able to tell that there is a signal, but it could not make sense of it. In the retina, it is the function of the intervening layers to make sense of the signal. The intervening layers in the retina are the bipolar cells, horizontal cells, amacrine cells, and ganglion cells. The bipolar cells act like an amplifier for the photoreceptors as well as an inhibitor, depending on the signals they receive from the photoreceptors.
