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.
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.
To use this camera as a digital exposure metering, first switch to Digital
Exposure Metering mode, then set the [Sensitivity], [Exposure Step] and
[Color Mode] on the [7 Dig. Exp. Metering] menu.
