Shadows Highlights Correcting backlit photographs with the gradation curve

Backlit photographs constitute a difficult situation in photography. The surfaces of the photographed objects in the foreground appear shaded. In a contrary but similar manner, photographs taken with a flash are overexposed in the foreground. As long as there is enough distinguishable image information available, you are able to improve these photos considerably. In some programs, you can use a Shadows-Highlights function to improve your image. For GIMP, there is a plug-in; yet GIMP's Curves function is suitable for making these corrections. Select the image ship.png from the Samplelmages folder on the DVD.

Generally, the procedure to brighten up shady image sections is to set one or more points on the curve, in the area of the shadows, and to slide them upward. In return, the image gets more detail and contrast in the bright areas because the highlights are darkened. Using the Curves function accordingly, you can correct overexposed flash photographs.
