Photoshop提供了許多功能強大的工具,可增強、修復和校正圖像中的顏色和色調(亮度、暗度和對比度)。在調整顏色和色調之前,需要考慮下麵一些事項以避免產生一些不必要的顏色丟失和錯誤。


①校正圖像應使用經過校準和配置的顯示器。因為不同的設備間存在著顏色空間的差異,在顯示器上看到的顏色不能代表文檔中的實際顏色,所以校正顯示器,創建顏色配置文件在色彩管理方面的作用極為重要。


②調整圖像的顏色或色調時,某些圖像信息會被丟掉,所以在校正前應做好圖像的備份。


③為了盡可能多地保留圖像數據,最好使用每個通道16位的圖像(16位圖像)而不使用每個通道8位的圖像(8位圖像)。因為 Photoshop CS已經改進了對16位圖像的支持。

④盡量準備使用調整圖層來調整圖像的色調範圍和色彩平衡,而不是使用調整命令對圖像的圖層本身直接進行調整。

⑤在調整圖像前應仔細查看圖像的直方圖。
