Open the Original Photo. For this example I used the New Adjustment Layer option. In the color channel select box, select the Red channel. Place the cursor in the middle of the graph line. When the word add appears next to the cursor, click to add a point.
Red channel Drag the point down and to the right.
This will increase the points Input Value and decrease it's Output value. What you are doing is reducing the brightness value of reddish pixels. Now you have made a quick color correction. Now lets adjust the Green and Blue channels to further enhance the photo. Bring up the C urves adjustment panel.
