Abstract
The principle of a null-indicating densitometer has been adapted to the measurement of camera lens iris settings. An optical system calibrated in accordance with the described technic is rendered amenable to precise calculation of the luminous flux per unit area in any part of the field, with particular stress laid on the axial condition.
