Most point-and-shoot cameras have a simple exposure override facility, normally allowing you to overexpose or underexpose your picture. So if the subject is predominantly dark, experiment by overexposing to compensate. If the subject is predominantly light, then underexposure is the way to go. Try taking a test picture, look at it on the screen on the back of your camera, check the histogram, and adjust your exposure compensation. Don't be afraid to shoot four or five versions, as the LCD screen is not always accurate. You can delete the bad pictures later.

大多自动数码相机都具有曝光优先功能，一般都允许你在拍照时过度曝光或曝光不足，如果被拍摄物体整体光线比较强，可以减弱曝光强度，如果被拍摄物体整体光线比较弱，可以选择过度曝光，试着多拍摄几张照片，通过相机背部的液晶屏观察柱状图，调节曝光补偿等级，因为液晶屏的显示效果不很精确，别嫌麻烦，多拍几张照片，之后，对于效果不理想的照片可以删除。
