This is one of the simplest extinction meters and, reportedly, quite accurate. In early models the number just visible in the 'finder' is aligned with a box depicting the light conditions and subject. The shutter speed and aperture pairs can then be read. This was accurate for one film speed only. If a different speed was used adjustment was made after lining up the subject box and number. On later models a table gave an index for the film speed this was combined with the light value number e.g. index = C, number = 8, gives C8 which is then aligned with the subject box. The drawings in the subject boxes differ between examples. The price was 5/- in 1939. A cine model was also produced c. 1936.

Meter Type:
Extinction.

Calibration:
Shutter speed: 1/1000 - 64s. Aperture: f2.8 - f22.

This American meter operates in a similar way to the Leudi but the reading is taken looking down into the meter, a table on the back of the meter shows the shutter and aperture combinations. A very similar meter was produced in Germany under the name of Lumy.

Serial Number:
A3203, shown on guarantee .

Notes:
The instruction sheet carries the name of Maxim Instrument Co., Trenton N.J. at 221 E. State St. The Pierce name is shown on the guarantee at the same address.

With:
Instruction sheet, guarantee. Box

An index is set against the emulsion speed, shown as 1.5 - 200. A window in the meter displays a range of letters A - H, the least distinct corresponds to the light value. On the front of the meter a dial showing the sky conditions, or artificial light, is set against the A - H value. The shutter speed / aperture pairs can then be read. A table in the instructions shows the speed of various plates.

Hauff Belichtungsmesser

1930s

Meter Type:
Extinction.

Calibration:
Shutter speed: 1/2000 - 10m. Aperture: f2.8 - f16.

With:
Case.

The least distinct number is noted when looking through the meter, a transparent plastic sleeve is moved to align with the number, the shutter speed and aperture pairs can then be read in the column depicting the type of scene. The meter is marked 'System Heinz Kilfitt' who was the designer of the meter.

Expophot

c. 1938

Image of Expophot

Meter Type:
Extinction.

Calibration:
Film speed: 7 - 22 DIN, 14 - 29 Scheiner. Shutter speed: 1/1000 - 30m. Aperture: f1 - f64.

The least distinct of a set of numbers (which are aperture values) is noted when looking through the meter, this is set on the face of the meter against the film speed, the shutter and aperture pairs can then be read. There are three scales of shutter speed for different light conditions, sun, dull and indoors. The meter is used at waist level, a flap covers the light-scale when not in use.

The US patent is in the name of Bing.
