What is the relationship between the whole and the part in commodity photography?

In commodity photography, the relationship between the whole and the part is a dialectical relationship of interdependence.

The whole is made up of parts, no parts and no whole. They exist through comparison and show their own characteristics. The whole contains some contents and characteristics of the whole, which exist in mutual comparison, interdependence and tolerance.

The whole and the part are the unity of opposites. The whole dominates, determines and plays a leading role. Part affects the whole and is in a subordinate position. Under certain conditions, the key part also determines the overall development.
