Fujifilm FP-100C was a professional peel-apart instant color film with an ISO speed rating of 100, designed for cameras accepting 3.25 x 4.25 inch (8.5 x 10.8cm) instant film formats. The film featured fine grain structure and rich tonal gradation, making it ideal for professional applications including passport photography, commercial test shots, and presentations under varied lighting conditions. Optimized for daylight and electronic flash photography, FP-100C became the primary instant film choice for professional and ID photography markets after Polaroid's discontinuation. This film essentially kept Polaroid pack film cameras viable long after the original Polaroid company's demise, though it too has since been discontinued.
