When a picture of uneven distribution of light and not like Digital Camera Battery backlight is of great differences that light and shade, can be made the central partial key metering modes.
The central partial key metering modes canon nb-6l battery (also call center weighted metering modes in order to measure certain area) taken the brightness of the body, the rest is mainly taken body brightness is complementary, digital photograph comprehensive figures give opportunity for value, its coverage than metering center-weighted average metering or spot metering mode.
The central partial key metering modes YuGuangYuan applicable in digital camera on a left, the measured data basic accurate. canon nb-5l battery When the user is close to the body when taken local, the central partial key metering modes and the center-weighted average metering or spot metering metering effect is not big, when the user differences metering of short JiaoDuan expand use lens range, the central partial tricks on average metering modes and metering modes of the difference is not big. Metering effect The central partial key metering modes is very wide, the use of the user can adjust the size of the picture frame, manual control the central focus of metering modes metering range, which made various of metering modes metering effect.
Light from a digital camera canon nb-4l battery to the right side of the face of light on a left model brightness has a bigger difference, the use of the central partial key metering modes of light and dark can give consideration to the department.
Light and dark painting into two parts, use a central partial key metering modes close to mushroom, can make the metering by light irradiation mushrooms, this method and use the exposure accurate center-weighted average metering or spot metering mode equivalent.canon np-e3 battery
