ii ... ia," ii la AM !Ma • 22 EXPOSURE COMPENSATION When shooting in difficult lighting situations such as when the subject is situated against the light (direct sun, snow, a bright window) or when spotlighted on stage, etc., either additional or less exposure is required to override the influence of the strong backlighting and bring out the details of the subject. Such problems are easily corrected by temporarily altering the setting of the ASA film speed dial for the shot requiring exposure compensation. Backlit Subjects: For subjects with the sun behind them, standing against the light, bright snow, etc, compensate by lowering the ASA film speed value to half or four times the ASA film speed. For example: With ASA 100 film in the camera: reset the dial to ASA 50 or ASA 25 (this gives 2X and 4X compensation, respectively). With ASA 400 film: reset the ASA dial to ASA 200 (2X) or ASA 100 (4X). Spotlighted Subjects: For subjects on a spotl ighted stage, etc., decrease your exposure by doubling or quadrupling the ASA film speed value. For example . With ASA 100 film: reset the dial to ASA 200 (1/2X) or ASA 400 (114X). With ASA 400 film: reset the dial to ASA 800 (1/2X) or ASA 1600 (1/4X) Always reset the ASA dial to its original setting after employing exposure compensation.
