AI-assisted summary

Description from the seller

English, late 19th century, made of brass by R Field & Son, Birmingham, 6.8 cm high.

The Watkins Meter Company was a manufacturer of photographic light meters in Hereford, England. The company was founded after Alfred Watkins received a patent for his light meter in 1890. The Standard Meter was initially produced by R. Field & Co. from Birmingham; the Watkins Company took over production around 1900. The meter exposes a small section of light-sensitive paper, which darkens during exposure. The time it takes for the light-sensitive paper to darken to the same shade as the surrounding slit is the third input parameter used to calculate the correct exposure time for a given aperture and film speed, using the instrument's scale. Due to its age, the operation of the light-sensitive paper cannot be tested.
