ALCE - Advanced Local Contrast Enhancer for Photoshop

ALCE - Advanced Local Contrast Enhancer for Photoshop

Buy
$34.95

An easy-to-use and powerful Photoshop tool to effectively improve and finely tune the Local Contrast of an image, by means of a smart algorithm which avoids the clipping issues typical of other methods. The user interface is simple and clean, with just one slider and an opacity value, allowing the user to customize the effect in a straightforward way.

The algorithm analyzes the image through a user-defined value (called ”radius”). Such radius defines a neighborhood of interest, and within that area a contrast-enhancing manoeuvre is carried out without any clipping. This way, highlight details are safe and enriched, while the structure of shadows is boosted and yet preserves the original information.

It can be recorded in Actions, and with the bundled ALCE Automation Service panel folders of images can be processed in batch.
