bedroom_real lights

Used real lights, i.e sun light for litting the entire room. The physically accurate lighting caused the scene render time blow up to 2hr and 10 minutes per frame. Still need to set the quality higher for a better result.

Used custom lighting technique.  with photographic exposure control Render time = 20 mins The idea is to create a custom lighting set up that mimic the physically accurate lighting. Here I used a sun light with three extra lights to lit the scene.

Very same scene with little wider camera angle. But there is no photographic exposure control. Render time is almost identical, 20 mins per frame. You can clearly tell this is more CG than previous.
