histogram

One way to quickly check out if there's any area in your shot that is overexposed to this degree is to view the histogram on your shot..一个方法来快速检查在你的拍摄中是否有过度曝光到这种程度的情况发生可用拍摄中的直方图。

At this stage I will also check the histogram for clipped shadows and blown highlights and if necessary add some Fill Light and/or Recovery..在这个阶段为了检查省略的阴影和过亮的部分，我还会检查直方图，如有必要增加一些填充的光线或做一些补救。

If a significant data value skew exists for a column referenced in a query predicate, make sure that DB2 knows this, preferably by generating column-value histogram statistics using RUNSTATS..如果查询谓词中引用的列存在显著的数据值倾斜，那么要确保 DB2 了解这一情况，最好是使用 RUNSTATS 生成列值柱状图统计数据。
