A powerful way to
adjust images in Adobe Photoshop
What are luminosity masks?
Luminosity masks are grayscale pixel images based on the brightness values in your image. Because they are created from your individual photographs, each mask blends in perfectly and allows for precise tone-based selections. Luminosity masks allow you to adjust brightness, contrast, and color on specific tone ranges in your image without the need for brushes or other selection tools.
Why should you use luminosity masks?
Luminosity masks aren’t for every image, but they are incredibly powerful on images that contain subtle or complex tone ranges. Luminosity masks paired with Photoshop Adjustment Layers let you target your adjustments to specific tones. For example, you can subtly enhance contrast in just the highlights or shadow ranges of your image, and you don’t need to worry about using brushes.

How can I create luminosity masks?
Luminosity masks are created by making selections and storing them in Photoshop’s Channels Panel. You then load these channels as selections to use as layer masks. Luminosity masks are unique to each image, as they are based on the actual pixels in your photograph. The easiest way to create these masks is to use Photoshop Actions.
Photoshop Actions for Luminosity Masks
Luminosity masks require the use of Adobe Photoshop. I’ve created a complete set of actions that allow you to quickly produce 16-bit luminosity masks on any image. My complete set of actions includes the 11 standard (basic) masks, 11 Zone Masks (for even more targeted selections) and the Expanded Midtones (3 masks) for adjusting midtones while protecting the bright and dark tones in digital photographs. The complete set of actions is only available through my PDF eBook tutorial, Mastering Luminosity Masks. However, you can get my Basic Luminosity Mask action set for free here.
