Turn photos and illustrations into something that glows. Lumisan reads the brightness, edges, and saturation in your image to find where the light should live — then blends in a soft glow, sparkling patterns, or holographic color shifts. From a subtle highlight to a full holographic wash, it's built for real photos and artwork, not just neon stickers. Everything is processed on your device. Nothing is ever uploaded. Five simple steps get you there: Style → Area → Light → Finish → Save.
