Day to Dusk API
Twilight exteriors make strong hero images, but evening shoots are hard to schedule at scale. With the Roomagen day to dusk API, a daylight photo of a building is relit for the hour you pick (the sky turns, the light comes in at that hour’s angle and, after sunset, the lights already on the building glow) through one API call, and the model is told to keep the facade, planting and composition as photographed. Jobs are typically ready in 20–60 seconds.
