The Photographic Process and Film Sensitivity - Sprawls

- One of the most important characteristics of film is its sensitivity, often referred to as film speed. The sensitivity of a particular film determines the amount of exposure required to produce an image. A film with a high sensitivity (speed) requires less exposure than a film with a lower sensitivity (speed).

- While photographic film was traditionally used as a detector, various types of photoelectric detectors have replaced it. The photomultiplier (PMT) is a commonly used, sensitive detector where photons striking the photocathode cause the ejection of an electron if the photon energy can overcome the work function of the material used in fabricating the photocathode.

Film speed - Wikipedia
- https://en.wikipedia.org/wiki/Film_speed
- Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a slow film. Highly sensitive films are correspondingly termed fast films. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally …

- In digital photography, "sensitivity" is the equivalent to film speed. It is also sometimes referred to as "ISO equivalency." The higher the number, the “faster” or more sensitive to light is the film or your digital camera's sensor, meaning you need less light to get a properly-exposed image.
Light and Energy - How Photographic Film Works

- Infrared light is also invisible, but if it is strong enough our skin detects it as heat. It is the energy in each photon of light that causes a chemical change to the photographic detectors that are coated on the film. The process whereby electromagnetic energy causes chemical changes to matter is known as photochemistry.

- There is a separate layer in the film for each color: Red light forms a latent image in the red-sensitive layer of the film; green light forms a latent image in the green-sensitive layer; blue light forms a latent image in the blue-sensitive layer. The image is called "latent" because you can't detect its presence until the film is processed.
