Note on the Evaluation of Photographic Speed from Sensitometric Data,

Metadata

Doc Type: Journal Article
Article Type: research-article
Abstract: A method of ascertaining the gradient speed of a photographic material without the use of special gradient measuring instruments is pointed out. The derived formula shows the relation which must exist between density and log exposure at the value of exposure which is the reciprocal of the speed.
