Function

A gauge used in photography to measure the intensity of light in order to determine the necessary length of exposure needed to properly photograph a subject.

Technical

Created by German engineer Josef Dorn, this selenium exposure meter was said to be "unusual in that the centre of radius of a moveable sector shaped scale was located towards the opposite corner of the meter from the pivot of the printer. This provided a degree of compensation for the non-linear defection of the pointer". [Ref. 1] A similar version was distributed in the USA by Interstate Photo Supply Corp. They called it the "Record Prize" [Ref. 2].
