Digital Exposure Metering Function Digital Exposure Metering Function Digital Exposure Metering Function The Optio 750Z not only enables you take pictures and record movies as a high quality digital camera; it can also be used as an advanced reflective digital exposure metering. It can also function as a spot exposure metering when the zoom is in the Tele position. When using a single-lens reflex camera or a traditional film camera to take pictures, this digital camera can be used to meter the brightness of various parts of the subject in order to obtain the optimal exposure. Digital Exposure Metering Mode The Digital Exposure Metering mode is used to meter the brightness (light level) of your subject so as to calculate the optimal combination of aperture and shutter speed (exposure). This mode differs from the normal operations used to take pictures and play back images. Metering the light level is as simple as pointing the camera toward the subject and pressing the shutter release button. The Optio 750Z then automatically calculates the shutter speed and aperture according to the brightness of the subject.
