Produktbeschreibung
Instant film is a type of photographic film first introduced by Polaroid that is designed to be used in an instant camera (and, with accessory hardware, with many professional film cameras). The film contains the chemicals needed for developing and fixing the photo, and the instant camera exposes and initiates the developing process after a photograph has been taken. In earlier Polaroid instant cameras the film is pulled through rollers which breaks open a pod containing a reagent that is spread between the exposed negative and receiving positive sheet. This film sandwich develops for a predetermined time, depending on film type and ambient temperature, after which the positive sheet is peeled away from the negative to reveal the developed photo. In 1972, Polaroid introduced integral film, which incorporated timing and receiving layers to automatically develop and fix the photo without any intervention from the photographer. Instant film is available in sizes from 24 mm x 36 mm (similar to 135 film) up to 20" x 24" size, with the most popular film sizes for consumer snapshots being approximately 3 " x 4 " (the image itself is smaller as it is surrounded by a border).
