Advanced Local Contrast Enhancer

ALCE presentation image



ALCE is a Photoshop Extension performing a routine that boosts the image's Local Contrast, adding shape and a distinct 3D look, that might even remind HDR tone mapping.

Easy Interface

No need to tweak multiple options! ALCE's one and only parameter is the Radius: the smaller, the "more Local" is the contrast boost - the higher, the closer to Global is the adjustment.

Shadow Highlights

ALCE's algorithm, while boosting contrast, protects from clipping (i.e. the loss of detail) important and delicate tonal range areas such as the Shadows and the Highlights.

Batch Utility

You can record ALCE in Actions as a Filter, or use the provided "ALCE Automation Service" batch dialog to customize Saving options (file type, compression, etc), suffix, source and output folders.

    • Incredible 3d effects, useful in many occasions when photos are flattened or when lacking that little bit extra.
