A better alternative to reading the light in many scenes is to use an “incident” meter. Hand-held incident meters read the intensity of light falling on the subject and are usually taken from the subject position. Because they are not affected by variances in subject color or reflectance, incident meters accurately record the amount of light falling onto the subject. In the majority of situations, an incident reading is extremely accurate and records tones, colors, and values correctly. From the subject position, point the meter's Lumisphere (for 3D subjects) or the Lumidisc/Retracted Lumisphere (for flat subjects/copywork) toward the lens and take your reading.
