灰卡在数码相机上的应用1.决定白平衡时，拿出灰卡，让相机的取景器充满整个画面，不同的相机有不同的设定方式，但大多是进入“自定白平衡模式”对标准灰卡的白面，拍摄一张相片，DC便会得知在该光线条件下，什么才是”白色”。2.决定曝光值时，请使用灰面，如果有反射式测光表时，可以测光表的值做参考（测光表请贴近灰卡），可以改变焦距，令其拍摄范围涵盖灰卡。灰卡的其它作用1.在摄影棚的多灯作业中，可以决定主副灯的照明比。 2.可以简单地用来判断相机的色彩平衡。

an accurate custom white balance ensures an accurate image from the start of
each new photo session.
