Basic Operation Metering Systems Since brightness and film sensitivity determine the proper combination of shutter speed and aperture for correct exposure, measuring subject brightness is very important. The F6 provides three metering systems. With Matrix Metering (x 62), brightness data is detected using the 1,005-pixel Matrix sensor. With Center-Weighted Metering (x 63), brightness is detected in the central area of the viewfinder. With Spot Metering (x 63), sensitivity is concentrated in one of the 11 available focus areas. Exposure Light from the subject passes through the lens and exposes the film. Shutter speed and aperture control how much light reaches the film. The correct combination of shutter speed and aperture results in a correct exposure-a result provided by the F6's four exposure modes: Programmed Auto, Shutter-Priority Auto, Aperture-Priority Auto and Manual. Characteristics of exposure modes Symbol Exposure mode Shooting situations ¡ Programmed Auto P. 64 Camera controls shutter speed and aperture automatically, while allowing you to make other settings, such as Flexible Program (x 64) or exposure compensation (x 74). ™ Shutter-Priority Auto P. 66 You set your desired shutter speed, and the camera selects the correct aperture. Allows you to "freeze" the motion of a moving subject using a fast shutter speed or blur the subject using a slower speed. You set the desired aperture, and the camera selects the correct shutter speed. This lets you £ Aperture-Priority determine the depth of the in-focus area (x 164), Auto P. 68 so you can choose whether near or distant subjects are in sharp focus, or whether foreground or background should be blurred. ¢ Manual P. 70 Shutter speed and aperture are set manually. Long Time Exposure (Bulb) can also be selected. 27
