Lighting Change

Changes the time of day and the corresponding lighting mood of an architectural render or photograph — Golden Hour, Night, Dawn, mid-day. Geometry, camera position, framing and existing materials are preserved exactly. Only the sun position, sky, ambient color temperature, shadow direction and atmospheric register change. The time-of-day selector drives a sun-position-aware prompt that recomputes shadows coherently across the building, foreground and background. Window reflections and facade specular response are reconstructed for the new condition. Useful for quickly testing how the same project reads at different moments of the day, or for choosing the right hero shot light for a presentation deck — without re-rendering each pass at 40 minutes a frame on the studio workstation.

An architecture studio has a 3D render of a contemporary residential project, locked in mid-day light, but the client deck needs three options: morning, golden hour, night. Re-rendering each pass takes 40 minutes per frame on the studio's workstation. The studio runs the existing render through Lighting Change three times with different sun positions, gets three coherent atmospheric variants in seconds, drops them on the deck side by side.
