What is the film speed range typically used in consumer photography?

The film speed range typically used in consumer photography often falls between 100 to 3200 ISO. This range is ideal for general photography purposes as it provides flexibility for various lighting conditions and types of scenes. ISO 100 is suitable for well-lit environments like sunny days or studio settings, while higher speeds like ISO 3200 allow for capturing images in lower light situations without excessive motion blur or noise.

Using a film speed range of 100 to 3200 strikes a balance between image quality and exposure sensitivity. Lower speeds tend to produce cleaner images with less grain, whereas higher speeds can introduce more grain but are necessary for capturing images in challenging light conditions. This knowledge enables photographers to make informed choices based on their specific shooting circumstances, whether they are taking portraits, landscapes, or action shots.

The ranges provided in the other answer options extend beyond what is typically needed for consumer photography, where speeds above 3200 may be more relevant in specialized or professional contexts, such as low-light sports photography.
