Q
For the object
in bright light
For the object
in poor light
If the subject is in so bright a light that it causes the needle to scale
out, or when the photo subject is too dark to give sufficient impulse to
the needle, the sensitivity of the light meter is changed by shifting the
sensitivity lever on the light meter. If the index mark on the lever
shows the orange dot, indicating the need of high sensitivity (because
the object is dark), the aperture reading must be taken from orange
scale. Conversely, if the indicator shows the white dot, indicating the
need of low sensitivity (because the object is in bright light), the aperture
must be read ofi the white scale on the meter dial.
