英语语法分析

On a clear day, the sun is so bright that your camera's meter will tend to underexpose everything else in the frame.

如果天气晴朗，阳光是如此耀眼，这就会造成镜头内其它所有物体都曝光不足。

By positioning the subject near the light source and allowing some of the subject to underexpose, the photographer can let light touch only the most important part of the subject.

让被摄者靠近光源并有选择地让被摄对象的某些部分欠曝，摄影师能让光线照亮被摄者最重要的部分。
