Black light / Experimental

Black light

The Black Light tool mimics the effect of a long-wave UV lamp. Because long-wave UV light is not captured by traditional digital cameras, the filter attempts to recreate the effect using each pixel’s variance from its expected luminance value.

Like all PhotoDemon tools, a dedicated command bar allows you to save and load custom presets, randomize parameters, and reset to default values. Last-used settings are automatically saved and restored, and all changes provide a real-time preview (no click or mouse button release required).
