What is Film Speed? Film speed is based on an ISO number. ISO is short for International Standards Organization, the group that set the standard. The most commonly seen are ISO 25 to 3200. The lower the ISO number, the less sensitive the film is to light. It takes longer to expose film that is ISO 25 than film that is ISO 100.
Film with a low ISO number, from 25 to 50, is said to be slow film because of the slower shutter speeds required to photograph when using them. Film with an ISO from 64 to 200 is called medium speed film Film with a rating of ISO 320 or higher is often referred to as fast film because it can allow for faster shutter speeds under less than ideal conditions.
Why use a slower film? The resulting prints or slides are exceptionally sharp. Graininess is least apparent in pictures taken with a low ISO number film, that is properly exposed in good lighting conditions. By choosing the slowest film suitable for your photography, you can get the best possible prints. The rule of thumb for most snapshot-type photography is that you should use ISO 100 film for pictures taken indoors with a flash or outdoors in bright light. ISO 200 film is for general purpose photography with a mix of flash and available light ISO 400 is for sports or low light pictures without a flash.
