One of the more common problems in photography involves lighting. Photos taken in bright light often have little detail in the shadow areas since the camera is attempting to not overexpose the brighter areas. The Fill Flash filter allows you to lighten the darker, underexposed areas of a photo. If your photo's background is too dark, or you feel there's too much difference between the photo's light and dark areas, this filter is a good choice to help correct that problem.
Choose Adjust > Photo Fix > Fill Flash.
Use the Strength value to determine how much the darker areas will be lightened.
You may run into a situation where a photo has just enough of a problem with too-dark areas as well as too-light areas. In that case, try running the Fill Flash filter on the photo, and then the Backlighting filter.
