Exposure indicating device |
摘要 |
An exposure indicating device indicates at the same time a result of average light measurement which measures a light level of a substantial portion of a scene to be photographed, and a result of spot light measurement which measures a brightness at a small portion of the scene. One of the values of the average and spot light measurements is displayed numerically to indicate its absolute value, while the other is displayed as a deviation from the former value.
