This value is then selected with the large arrow on the dial under the meter and the exposure value can be read from the exposure scale on the dial. The dial is basically a lookup table of exposure values. In order to read in low-light conditions the baffle plate, which is normally fitted over the selenium cell, can be flipped down so the light directly hits the cell. As the plate is flipped, the meter scale is also replaced with a lower numbered version allowing lower light reading to be accurately taken. In order for the scale to be set up to the speed of the film emulsion being used, there is a small button at the front of the meter which can be pressed and the whole dial moved to set the film speed (shown in the red weston speed scale in the pictures above).

ItвЂ™s interesting that on a modern exposure meter (I have a Gossen digipro F) the film speed (or ISO as it is now refered to) is an integral part of every exposure because it can be easily changed. When these light meters were in common use film speed was something set when the film was loaded into the camera and forgotten. The letters shown on the dials (A,C and U,O) are there to show the range of brightness which can be recorded on black & white (U,O) and colour (A,C) film. These settings were used to make sure the light or dark areas in the picture are correctly exposed. This would ensure that the picture would be exposed so that the dark area was visible and any over exposure in the light areas was minimised.ДЇor example, if the photographer wanted to make sure that the dark area of the picture was correctly exposed he could meter on the dark area and set the U to that setting.

How accurate are these meters ? Well I went outside and used the Weston III to take a reading on these three pictures in my garden in manual mode. I would say that they are all under exposed by about 1/2 a stop so thatвЂ™s not too bad. If it turned out the meter always underexposed by a known figure, that would be easy to compensate for. Why would you want to use a hand held light meter ? Well there are some things which an in-built light meter (which measures the light reflected from the subject) is not good at. For example if you take pictures in snow and rely on the cameraвЂ™s light meter you will probably find that the pictures are under exposed by a couple of stops. The reason for this is that the cameraвЂ™s light meter is designed to average the amount of light in a scene and set the exposure appropriately. Gossen digipro f exposure meter manual#.
