Corona has a LightMix feature that lets you change the lighting after rendering.

Like many modern render engines, you can do more and more things after the render is complete. Take lighting changes, for example. A feature like LightMix lets you adjust things like light intensity and color. With Corona Render, you can do this before, during, or even after the rendering.

Corona also allows you to have more than one Corona Sky object. That means that LightMix can be used for even better results when creating different times of day within just one render.
