Reflected light meter reading
b. Incident light readings are measurements of the intensity of the light
by which a scene or object is illuminated (fig 4-21).
Use incident light
readings to determine the best average exposure when the general illumination
is at a low level. Hold meter near the object or the center of the scene and
aim the meter toward the camera, in direction of the light. If the light comes
from one side, point meter about halfway between the light source and the
camera. Never point the exposure meter directly at the sun.directly 1 q--0.2636 Tc
