1、打开图片,复制一层(好习惯)。http://bbs.jcwcn.com/attachments/month_1004/100422111766ab91ab21333bf1.jpg2、打开直方图面板,观察红绿蓝三个通道,可以发现,三个通道的高光部分不同程度缺失,像素集中在暗部。根据这个情况,我们可以先用色阶进行调整。http://bbs.jcwcn.com/attachments/month_1004/100422111706edcdb1b26dfb6c.jpg3、建立色阶调整图层,分别对红、绿、蓝三个通道调整如下。http://bbs.jcwcn.com/attachments/month_1004/10042211173380eaeb70d416c3.jpghttp://bbs.jcwcn.com/attachments/month_1004/10042211176ee706c12309cab1.jpghttp://bbs.jcwcn.com/attachments/month_1004/1004221117b8bad0a5a6dcb291.jpg4、调整后的效果如下,可以看出图片有些偏黄。http://bbs.jcwcn.com/attachments/month_1004/1004221117ed94472e49010a88.jpg5、打开通道面板,观察三个通道,发现红通道和绿通道还可以,蓝色通道损失较大,而且显得很脏~看来得想办法进行修复。http://bbs.jcwcn.com/attachments/month_1004/1004221117ade207673a4b2338.jpg6、建立通道混合器调整层,对蓝通道进行如下设置(使用红通道和绿通道的信息来对蓝通道进行替换,达到修复通道的目的)。http://bbs.jcwcn.com/attachments/month_1004/10042211177061c30db4be534f.jpg7、观察图像,图片颜色基本正常了,但有些地方显青色和蓝色,使用可选颜色进行调整。http://bbs.jcwcn.com/attachments/month_1004/100422112083aaca0f8eaccb30.jpghttp://bbs.jcwcn.com/attachments/month_1004/1004221117fc2f953d57edc88e.jpghttp://bbs.jcwcn.com/attachments/month_1004/1004221117fcfacfbbb3f0c5a9.jpg8、加强点对比度。http://bbs.jcwcn.com/attachments/month_1004/100422111736a2062784271068.jpg9、曲线稍稍提亮。http://bbs.jcwcn.com/attachments/month_1004/1004221117ccf8bd2af75fb0dd.jpg10、随便磨下皮,方法在此不再叙述。http://bbs.jcwcn.com/attachments/month_1004/10042211172c74650d2f28b75c.jpg11、仔细看下图片,有点偏红了,使用色相饱和度,稍稍降点红色。http://bbs.jcwcn.com/attachments/month_1004/1004221117286b05c5a5e6c572.jpg12、锐化一下,收工。http://bbs.jcwcn.com/attachments/month_1004/1004221120b1a2d17ef4811ebd.jpg
