About Lumen Tool

Lumen Tool is a browser-based 3D portrait lighting simulator that offers an accessible and realistic way for artists, photographers, and designers to experiment with lighting setups. Unlike traditional desktop software or outdated browser tools, Lumen runs entirely in your browser, requiring no installation or account creation. Its lightweight design—under 1MB HTML file—loads in under a second and uses Three.js to render shadows and lighting effects in real time, providing a smooth, interactive experience. Users can quickly move a virtual light source and instantly see how shadows and highlights shift, making it ideal for exploring different lighting scenarios without costly equipment or complex software. Its simplicity and speed make it a unique tool for creative experimentation and learning about portrait lighting fundamentals.
