strongly that built-in meters can provide equally accurate results, but only if you understand
how they measure the light or subject and then use them properly. You might then appreci-
ate the speed and simplicity of using such meters, especially when you work with a handheld

Refl ected Meter Readings
Refl ected meter readings, whether made with a handheld or built-in meter, are more practical
and much faster especially in location and handheld photography because the meter reading

by the sensitivity of the fi lm and the amount of light that falls on the subject. (2) If an
incident exposure meter reading indicates that the subject requires a lens setting of X, this

speed is used whether you photograph a black or a white lighter under the same lighting. (4)
Refl ected light meters give higher readings (smaller apertures) for light subjects than for dark
ones, even though the same amount of light falls on both.
