Fast color correction using the LAB color space. - Dreamstime
Open our photo menu File - Open. Open the photo you're going to adjust. Then go to menu Image - Mode - Lab Color. We translate our image in LAB color space.Then go to the Channels palette, and see that we have new channels, namely, Lab, Lightness, a, b. With the latter two channels we are going to work, namely to a channel and a channel b.Select a channel (the image will turn gray) press Ctrl-m. A dialog box "Curves". In this window we see the histogram and the two triangles below it (black and white). Here we are with them and work with. You can change the value of the black triangles the mouse in the range -128 to -102. The value of white triangles, you can change the range of 127 to 100. After the changes, press OK. Repeat the same operation with the channel b used.
After work you have transactions with the channels a and b Lab channel enable (you have activated all channels) and look at the result.
I think that it does not upset you.
Attention! Following the work done on color correction do not forget to come back to the color space RGB. To do this, go to menu Image-mode-RGB Color. That's actually the whole method.
I hope this method of color correction will be useful to you and speed up the processing of your photo.
