How do adjust the brightness of mid-level tones in an image?
If an image on the page appears to be too red, maybe even too green. There is a simple and easy tool for this adjustment. Go to IMAGE→Adjust→Change Gamma… On the gamma menu you are given the individual settings of each level in an image, and one for the adjustment of each level as one referred to as the Master level. To adjust the settings drag the individual scroll bars to the right to increase their levels or to the left to decrease their levels within an image.
