Photo Color Correction

Adobe Photoshop Tutorial

Step 3 - Brightness/Contrast

Layer > New > Adjustment Layer > Brightness/Contrast
Brightness: +10
Contrast: +10

Further brightening was done using the main control setting for this purpose (Brightness/Contrast), without making the brightest parts of the photo (hair) lose too much detail. Contrast was added, without making the darkest parts too black or dark, and limiting their size in any one area and overall within the picture.

The result of the more flattering brightness and contrast includes the undesirable side effect of making the red dominate in the darker areas of the picture (her face, lips, and part of her shoulder) to the point where it looks weird, not even like a bad sunburn.

You can also see red/pink on lighter shades of her hair, and at the edges of her arms and shoulders. And if you look really closely, you can see the water itself has a subtle red/pink tint. It is better than the original murky green/blue/black, but it is still not a true blue.
