Allows you to “freeze”the motion of a moving subject using a fast shutterspeed or blur the subject using a slower speed.You set the desired aperture, and the cameraselects the correct shutter speed. This lets youdetermine the depth of the in-focus area (x 164),so you can choose whether near or distant subjectsare in sharp focus, or whether foreground orbackground should be blurred.Shutter speed and aperture are set manually. LongTime Exposure (Bulb) can also be selected.Characteristics of exposure modesMetering SystemsSince brightness and film sensitivity determine the proper combination of shutterspeed and aperture for correct exposure, measuring subject brightness is veryimportant.The F6 provides three metering systems. With Matrix Metering (x 62), brightnessdata 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 SpotMetering (x 63), sensitivity is concentrated in one of the 11 available focus areas.ExposureLight from the subject passes through the lens and exposes the film. Shutter speedand aperture control how much light reaches the film. The correct combination ofshutter speed and aperture results in a correct exposure—a result provided by theF6’s four exposure modes: Programmed Auto, Shutter-Priority Auto, Aperture-PriorityAuto and Manual.
