Abstract
The use of infrared-sensitive film for making measurements of the infrared reflectance of pigmented lesions has been described previously (Marshall, 1976, 1980, 1981). The present paper describes the use of an experimental ‘instant’ infrared film produced and made available by the Polaroid Corporation. The film was used in a small photographic photometric study in which it was compared with a standard infrared-sensitive negative material.
