Using the Luminance Range Tool

The Luminance Range tool allows you to focus adjustments on specific brightness levels within a photo, making it easy to target and enhance particular areas of an image. Adjust the settings for the mask such as the Exposure, Saturation, Vibrance, Temperature, Tint, Fill Light, Contrast, Clarity, and Color Strength, as well as Color EQ, Tone Curves, and Sharpness in one or a series of luminance masks over the photo. For example, instead of adding Fill Light to an entire photo, add the fill light to certain areas, such as back-lit subjects.

Using the Luminance Range Masking Tool on the Detail Tab

Sharpness

Move the Sharpness slider to the right to sharpen the area affected by the mask, or move the slider to the left to blur the area affected by the mask.

Luminance Noise Reduction

Reduces graininess or "noise" in the image by smoothing our variations in brightness (luminance) while preserving detail and texture.

Color Noise Reduction

Reduces unwanted color artifacts or "color noise" in an image by smoothing out random variations in color while maintaining overall image detail.
