A New Ultra-High-Speed Black-and-White Reversal Film

Warren W. Evans

A new high-speed, rapid-processing black-and-white reversal film, rated at 500 Daylight/400 Tungsten for normal reversal processing, has grain comparable to earlier high-speed reversal films and offers improved sharpness and excellent protection against flare and halation. Higher speeds can be readily obtained by increasing the first development time. Higher speeds are accompanied by some reduction in maximum density and slightly increased grain. Halation protection is provided by a special silver underlayer which is discharged during the reversal process, requiring no change from the normal reversal processing schedule. This new film is not suitable for use as a negative.
