For students using SLR cameras which require film, the following information outlines the basic information continuing in this course. It is also important for those shooting with digital equipment as well, because many film metaphors have remained in the controls and concepts of digital cameras.
Shooting with SLR camera opens up a whole set of controls, and thus knowledge to sucessfully make the images you want, and at the quality demanded, requires a strong understanding of technical concepts.
Film speeds are measured numerically. The lower the ISO number, the less sensitive the film is to light. Conversly,the higher the ISO number, the more sensitive the film is to light. Film speeds are rated by numbers that double in increments as follows:
25, 50, 100, 200, 400, 800, 1600, 3200,...
Higher film speeds (‘faster film’) are more sensitive to light, meaning you need less light to make a properly exposed image. This means high film speeds (800, 1600,...) can be used late in the day, or after sunset, or indoors.
Lower film speeds (‘slower film’) are less sensitive to light, meaning you need more light to make a properly exposed image. This means low film speeds (100, 200) will allow for images only in very bright environments- midday sun, open sky.
The consequence of faster film speed is this: with increasing sensitivity to light (higher ISO ratings), film looses it’s quality – images increase in ‘grain’ as the film speeds rise. However, ‘fast film’ can be used in lower light scenes, and is therefore a more realsitic film speed to often use.
The consequence of slower fllm speed is this: with decreasing sensitivity to light, (lower ISO ratings), film gains quality – less grain and better color saturation. However, “slow film” demands much more light (more exposure).
