HOW TO USE YOUR LIGHT METER.

Exposure meters provide a reliable means for measuring the light so that you can shoot each scene at the correct lens opening. Where the meter is built into your camera and coupled to the lens, the lens setting is made automatically. For at least 95 per cent of the shots made by most amateur photographers, you can rely on the lens opening indicated by

you exposure meter. Tlowever there are a few kinas oi subjects that tend to "fool" the meter. For example- Where the scene has a large dark area relative to the principle subject, such as a person lit by the sun but with dark foliage or trees as background, the meter is af f ected by the dark background and opens the lens wider than necessary so that the subject tends to be over exposed. ; You can easily adjust for situaiions like this by setting your meter dial at a somewhat higher A.S.A. figure than the exposure index of the film you are using. This will give you a smaller basic lens opening than if the index. were set for the actual speed of

the film and the principle subjects will then be more correctly exposed. For a bright background, the opposite conditions would apply, and it would be necessary to set the meter on a somewhat lower A-S.A. figure than the exposure index of the film being used. A little experience with these unusual sbjects will enable you to determine quite readily what index should be chosen.
