Alternative Techniques
There are several alternate ways to make the tonal range adjustments to this image. You could
use the Gain, Gamma, and Setup sliders as an alternative to the basic adjustment on the Contrast
slider. You could also use the Master ChromaCurve graph in the Curves tab.

Analysis of Original Image
Uncorrected image and reference image
In this example, two different cameras have been used to shoot the rock climbers. The second
camera is correctly balanced and shows good color characteristics, but the images from the first
camera show a strong blue cast and are too dark. Corrections can neutralize color and raise the
brightness level in the first image so that it more nearly matches the second. You can use the
image from the good camera as a reference for the corrections. In this example, the corrections
use the Curves tab. One advantage of Curves tab adjustments is that you can make quite complex
changes without having to alter many controls. The corrections in this example add and then
move a single control point in each of two ChromaCurve graphs.
