-CONTROLS IN DETAIL-continued------ - - - Exposure measurement in special cases The exposure meter of the Nikon FM2 adopts the centerweighted exposure measurement system in which approxi- mately 60 % of the total amount of light is measured by the 12 mm·diameter circle at the center of the focusing screen. When the background of the main subject is too bright and the main subject is not centered within the frame , the result is underexposure (see Fig . 1). When the background is too dark and the main subject is too bright with the same framing as above, the result is overexposure. To compensate1) Focus on the main subject with the composition you have in mind. 2) Move the camera to center the main subject in the viewfinder (see Fig. 2) and perform exposure measurement. 3) Move the camera back to the position described in 1) with the exposure setting described in 2) and depress the shutter release button. This way, you will be able to obtain correct exposure. Fig. 1 o Underexposure ~ I I I I I ..... - - , I I I I Ie + I I I I I ____ J 24 Fig. 2 Correct exposure
