Abstract
429,597. Photographio surveying. FERNSEH AKT.-GES., Goerzallee, Zehlendorf, Berlin. Nov. 29, 1933, No. 33450. Convention date, Nov. 29, 1932. [Class 98 (i)] A method of photographic reconnoitring or surveying from mobile craft in fog comprises the steps of exposing an infra-red sensitive film in the gate of a photographic camera, developing the film with a rapid developer, such as metol-hydroquinone with an alkali hydroxide accelerator, fixing, as with an alkaline solution of potassium cyanide, and viewing, the steps being effected in rapid succession in a single apparatus of known type. The step of fixing may be omitted. The pictures may be converted into positives by known reversing treatment. Specifications, 2954/09, [Class 98], and 5330/15, [Class 98 (i)], are referred to.
