Spot Metering Prove Exposure Meter with Box in Very Good Condition The simplest tool for selective metering in the film plane. The probe, which has been developed in close cooperation with Minolta, fits F Flashmeter III, Flashmeter IV, and the anemometer IV compatible. An adapter plug (optional) also enables the use of boosters on the FCM 2 Broncolor.
The booster can be used directly in any Sinar measuring rear wall. With a measuring tape 9 x 12 you can also in almost all commercial large format cameras in the formats / 4 x 5 ", 13 x 18, 18 x 24 / 8 x 10" be used. The way of working with the booster: a highly sensitive silicon cell of approx. 2.4 mm size is x 2.8 Sinar booster.
This small, well-defined area enables precise selective measurement - time - as well as Flash. The measuring cell into working position is pushed when the probe is switched on and a led indicates whether the cell is selected. The measurement is carried out at the working aperture as usual by pressing the scan button on the meter. The display of the meter displays the measurement result to 1/10 value exactly. By also measuring the contrast range between the brightest and the darkest part.
