X-Rite ColorChecker
★ 许多数码相机和视频摄象像机可让你自定义白平衡。进行这样的操作之后，无论当前照明条件如何，相机的白.灰.黑都会还原中性，CCD内色偏也会被纠正。
★ 一般来说会用一张复写纸或白色T恤衫进行白平衡。它们可能看起来是中性的，其实很多时候并不是，因此往往导致错误的白平衡。
★ 爱色丽ColorChecker白平衡卡可以一直保持光学中性。这意味它们反射同等量的红.绿和蓝色光，每次都可以给出真正的白平衡。
★拿出白平衡卡，置于场景内，保证照明光线与拍照时用的完全一致。
★把照相机靠近白平衡卡直到它填满取景器，并按相机中自定义白平衡的说明进行操作。
★可在任何光源条件下，准备调整相机白平衡

功能描述
The Xrite ColorChecker White Balance card is a full size version of the white reference square used in the standard 24-patch ColorChecker. This white is scientifically engineered to provide a precise uniform surface that is spectrally neutral (reflects equal amounts of red, blue and green) in all types of light conditions. The photographer can now have confidence that the camera raw image is as close to real life as possible.
ColorChecker White Balance gives photographers a way to adjust the digital camera’s color sensitivity to exactly match the ambient lighting conditions, in effect, change what that the camera ees. The perceived color of white often changes based on ambient conditions - outdoor it is perceived to be cooler, indoor it is perceived to be warmer and under fluorescent light it is perceived to be greener. Even in a controlled studio environment, establishing an accurate custom white balance ensures an accurate image from the start of each new photo session.
