When simulating set reconstruction, lighting that matches the scene is important, such as flames, neon lights, sunrises, lightning, etc. Moreover, the actual situation of light in the real environment is complex and cannot be recreated by simple lighting effects/operation. It is often dynamic. The set with various points, faces and diverse colors, it is difficult to simulate with simple lighting setups.
There may be highly reflective surfaces of metal or glass on actor/actress’s accessories or surrounding objects, which will reflect the shape and color of the light source. If you want to reconstruct the scene in green screen/previous set environment, the light source must completely match the environment in pre-recorded footage.
