What kind of lighting conditions do indoor photography need to have the effect of outdoor natural lighting?

Indoor photography generally requires a three-light area, and five lights are better if conditions permit.

First of all, to determine the light level of the main light, generally, auxiliary light should be used in the opposite direction and side direction of the main light, and the intensity and irradiation area should not exceed the main light, so it needs to be softer. Generally, the background light should be placed on the back of the subject, mainly to prevent the subject and the background from mixing together. This kind of light does not need to be too bright, and it can distinguish the background from the subject.

Of course, it is not necessary to add a reflector in some places where light is needed, which depends on the specific situation.

As for the effect, the side is completely determined by the main light, and how the main light hits is what the effect is, and the auxiliary light can be slightly adjusted. Such as front light, back light, side light, top light and so on.
