高光點不一定是最亮點圖像中的高光點不一定要設在最亮的可印刷值上

   print高光點調節

高光點不一定是最亮點圖像中的高光點不一定要設在最亮的可印刷值上， print例如可設在20%的亮度上以用於圖像特殊效果的正確顯示。

在前面層次校正中講過應盡量將高光點設在最亮的可印刷值上，究其原因是可以增加階調的範圍， print從而加大圖像的對比度，擴大圖像的層次表現範圍。

許多有藝術性的調子較平的圖像， print如婚紗攝影中的一些效果照片，如果按上述方法校正就會違背攝影師的意圖。

層次調節和顏色調節是否會有相互影響層次調節和顏色調節都會相互產生影響。 print歸根到底所有的調節都是像素的色彩數值的改變。

因此層次調節時必然會影響到顏色的變化，特別是顏色的亮度值的變化。反過來，色的數值的改變也會使層次產生變化。

例如某顏色的M色增加，則其亮度會減低，層次也會產生相應變化， print特別是K版的顏色增減對層次的變化影響更為明顯。總之，層次調節和顏色調節會相互影響，只不過側重點不同而已。
