Edit specific areas
It’s easy to work on a particular area with the Adjustment Brush Tool. Set the Size with the [ and ] keys and change the Feather to give yourself a soft or hard-edged brush. You can then paint over the area you want to adjust and change values such as Exposure, Saturation and Sharpness. For this image we reduced the Highlights and increased the Shadows to boost contrast on the head of this waxwing.
