Indoor photographic lighting

The play of the three lights is a main light, an auxiliary light and a side light.

The corresponding position and light brightness are the maximum of the main light, while the auxiliary light and side light are the problem of position. Side light can reflect the edges and corners of the subject, and the secondary light+reflector at the corresponding position is used to eliminate the shadow formed by too much light. Of course, there are many small household appliances you mentioned, so you need some corresponding filter paper. I don't know the answer. Ha ha.
