There are many lighting techniques in commercial photography. For example, the auxiliary light source may be a soft astigmatism lamp or a reflector. In color product photography, the main light is usually arranged at a position higher than the product. If the shape of the subject is complex, a few small lights can be used to produce appropriate highlights. Commercial photography has many lighting techniques.
