Watch--built-in metering metering regulation of skills

Because hand-held watch needs with separate metering, and now the digital camera CANON PowerShot S45 Battery will bring the metering system, so most people will choose to use the camera to own in metering system.

Adjust metering modes is actually very simple as long as found on the camera CANON PowerShot S200 Battery metering modes and through the turntable or adjust key direction regulate key on the adjustment, to choose the right in the mode, press the ok button.

Still have a kind of regulation way is by within the camera menu finish.

The general camera CANON PowerShot S400 Battery metering basically divided into three categories: matrix, the central focus for metering, center-weighted average metering or spot metering.

The name is metering matrix Nikon saying, and that is to evaluate the Canon in metering, other different cameras were also different names. But they are the mode of operation of the basic is the same, is all the images will QuJingKuang into DuoGe area, each camera CANON PowerShot S410 Battery have their own different partition how much, the 14, and as many as 256 of the 35, then respectively for each chart on after the results and the district within the camera material analysis comparison, works out a exposure combination.

The central focus of controversy in the name of metering no matrix so big metering, its operation methods and matrix similar metering. It is first measurement point of the image reflects the light, in the calculation of the central part of the picture to considerable proportion of, about 60% ~ 75%, the other part of the may be less than 40%, so it is with the brightness of the screen to decide exposure value, ensure that the central the foreground subject correct exposure.

Center-weighted average metering or spot metering, actually and handheld center-weighted average metering or spot metering table range almost, HuaJiao range is about 3 ° in the middle of the picture ~ 10 °, accounts for the whole picture of 2% ~ 10%, the scope for center-weighted average metering or spot metering is very small, it only in order to measure range of brightnesses to decide exposure value, completely from CANON PowerShot SD110 Battery other reflects the light interference, so can come to the small scope the most accurate exposure value.
