Have you ever wanted to have control of your light source after the fact?

What it does:

LC Lighting Control — post-process relight (no re-generation)

• Takes your photo, a normal map (surface facing), and a depth map (near vs far). Optional mask = who is the subject.

• Normals decide which parts face the light (bright cheek vs dark cheek). Depth decides what blocks the light (head on a shoulder, body on a wall).

• Optional mask blends in a simple “dome” of fake normals so the subject still reads as a 3D form if the real normal map is weak. It does not cut the person out of the background.

• Math (plain language): each pixel is multiplied by how much light hits it. Facing the key = brighter; turned away or occluded = darker. Ambient is the floor so shadows don’t crush to black. No color tint — only light and shade.

• Two lights can add (key + fill). A light at zero intensity is off (no light, no shadow).
