This pack of Black & White Spectra Instant Film from Polaroid Originals contains eight sheets of film for use with Polaroid Image/Spectra-series cameras. Characterized by its wider, more rectangular format compared to other Polaroid film types, this film has a glossy image area of 3.5 x 2.9", which is surrounded by a traditional white border. The ISO 640 film produces monochrome images with a long tonal scale, dark blacks, and bright whites. Each shot develops in 5-10 minutes after exposure, and the film should be stored in a cool, refrigerated, but not frozen, place before use.
