Polaroid ISO 400 black and white films extend the convenience of instant proofing with a high-speed emulsion. Polaroid ISO 400 black and white films offer photographers who work with faster emulsions the ability to proof and expose at the same camera settings.The ISO 400 films are especially well suited to use alongside ISO 400 color and black and white negative films, as well as high-speed transparency films. The ISO 400 emulsion is exceptionally stable, yet processes in just 45 seconds to yield a finished print that needs no coating.
Working on location, particularly under mixed ambient and flash lighting, has never been easier. Thanks to a perfect speed match between the instant image and final film, the effect of every camera adjustment can be seen on the proof just as it will appear in the finished picture.
Gone is the need to reset the camera after proofing. Never before has instant proofing been so much in harmony with ISO 400 photography.
