The light sensitivity of a specific instant film is designated by a numerical value. This value, often referred to as its speed, indicates how much light is required to produce a properly exposed image. A higher number denotes a greater sensitivity to light, allowing for use in dimmer conditions or with faster shutter speeds.
The designated film’s speed facilitates capturing images in a variety of lighting scenarios. Its relatively high sensitivity, compared to some other instant films, offers versatility in both indoor and outdoor environments. Historically, this film type gained popularity for its balance between image quality and usability, making it a staple for instant photography enthusiasts.
