Halation creates secondary ghost images in the film, which to photographers is bad because they are a by-product of unintentional light and film interaction. F IGURE Light interaction. 1 CHAPTER 3 FUNDAMENTALS OF PHOTOGRAPHY AND CINEMATOGRAPHY F IGURE Light passing through film. 2 Most modern films have an antihalation backing to prevent this from happening. Antihalation backing is normally dark brown when dry and after development is sometimes seen dissolved as a pinkish-red coloration. 2. The film and light interaction is really more complex than just irradiation and halation.

The white domes “average” the amount of light shining on the scene; the flat discs are used to evaluate the individual light’s lighting ratio. Most commercial photographers and cinematographers use incident light meters because they can easily measure the various light levels falling on a scene without the subject influencing the reading. However, one difficulty in using incident light meters is that they cannot meter the light falling on the top of a mountain or on a cloud. In these instances, a reflected light meter with a narrow sensor area is a better choice.

Cones are responsible for acute detailed color vision. The central area where cones are located and where detailed color vision occurs is called the fovea. Cones make it possible to see the warm hues of a sunset, the rich greens of the forest, and the cool blues of the ocean. There are also red, green, and blue cones in the retina that detect the millions of hues we see. Each type of cone is not limited to “seeing” one color or another; rather, their spectral sensitivity overlaps, and they communicate with each other in detecting varying hues.
