The Effect of Directional Development,
Abstract
The permissible values of the directional effect in cinematography were approximately determined. The appearance of the directional effect in movie positives can be obviated by using speeds of film movement > 2,000 meters/hr for Metol hydroquinone developers and speeds > 1,000 meters/hr for Phenidone hydroquinone developers. The appearance of the effect in movie negatives can be averted only by using spray-bath development. An attempt was made to quantitatively evaluate the conditions of the movement of the developer in the developing machine and the relation between the directional effect and the width of the photographic layer.
