Select and mask anything, visually! With Lumenzia, you get a full screen preview of the mask before you apply it. Interactively click on the image to select (or deselect) the tones/colors to the degree you wish. No guesswork with adding and subtracting channels. Isolate the mask to to specific parts of the image with a simple selection. And you can combine group masks to easily see the overall mask impact. It’s never been faster and easier to create or customize the right mask. And the masks are created in 16-bits, allowing for smooth transitions in extreme masks.
Click to pick! You don’t have to know which mask to use, just use the built-in zone and range tools to create the right mask automatically.
It’s stays out of the way. Lumenzia offers a compact panel with only the buttons you need, and completely eliminates the need for the channels pallet. This leaves room to easily see your images big and beautiful, even on a laptop screen. Every action in Lumenzia creates just a single history step, so you can undo anything with <ctrl>-Z. And because Lumenzia is programmed in JavaScript, it’s smart enough to take care of errors and other tricky situations for you.
Simplify exposure blending. Automatically stack, align, and sort your exposures light to dark for blending.
Smaller files. Lumenzia doesn’t use channels, so your files stay small. Additionally, it offers BlendIf and vector masks to avoid layer mask bloat, as well as a "Combine" tool to reduce the impact of group masks. A typical TIF file from a Nikon D800 grows from 200MB to 1.4GB when creating channel masks, but would remain the same 200MB size in Lumenzia. And Lumenzia can combine group masks to significantly cut down on file size, often reducing file size by 20-50%!
Beautiful vignettes with ease. Just draw a selection around the target area to create a vignette of any size, sharp, or position in the image. The vignette can be easily modified, inverted (to lighten the center) or combined with luminosity masks (to avoid darkening shadows too much).
For more information, please see the Lumenzia FAQ and full list of features.

System requirements: Lumenzia is compatible with Photoshop CS6 – CC 2018+ on both Windows and OSX. Lumenzia does not support CS5 or earlier (however, you may wish to try my free luminosity masking panel/actions instead). Note that the CS6 user interface functions the same, but looks somewhat different (see the FAQ link above for a comparison).
