instax film incorporates Fujifilm's highly regarded thin-emulsion technology. Providing thinner, more consistent emulsion layersIn combination with Super Fine Grain technology, this minimizes random scattering of light at the instant of exposure, assuring maximum sharpness and brilliance. Quick image formation, excellent control of color dye dispersal, and reduced diffusion in the image-forming layers further contribute to sharpness.By producing small grain that is consistent in size and shape, SFG technology allows Instax film to deliver remarkably smooth, fine-grained performance even at its fast ISO 800 film speed.
