Description

Предмет изобретени Subject invention

Способ определени  времени про влени  и оптимальной экспозиции путем визуального сравнени  плотности испытуемого негатива с плотностью эталонного нейтрально-серого пол , отличающийс  тем, что, с целью упрощени  и ус1ф|рени  процесса, ступенчатую щкалу клина-компенсатора совмещаютThe method of determining the time of occurrence and optimal exposure by visually comparing the density of the test negative with the density of the reference neutral gray floor, characterized in that, in order to simplify and enforce the process, the step wedge of the compensator wedge is combined

-И-AND

со ступенчатой шкалой пробного негатива до получени  равномерного серого пол  суммарных плотностей, а затем полученное серое поле уравнивают с эталонным нейтрально-серым полем путем смещени  клина компенсатора на целое число полей, по которому считывают экспозицию. Приоритет 02.04.73.with a graded scale of the test negative to obtain a uniform gray field of total densities, and then the resulting gray field is equalized with the reference neutral gray field by shifting the compensator wedge by an integer number of fields on which the exposure is read. Priority 04/02/73.
