Common composition forms include: well-shaped composition, regular triangle composition, inverted triangle composition, oblique triangle composition, vertical composition, diagonal composition, horizontal composition and curve composition.

Second, the static shooting techniques of different jewelry

1 Lighting selected during shooting:

To shoot a good work, the preliminary work is very important, and lighting is the most important link. Jewelry is characterized by high reflectivity, which can reflect most or even all of the irradiated light back. The simpler the shape, the more difficult it is to shoot a smooth reflective subject. Improper lighting will lead to uneven light or large contrast between light and shade, and there will be many disorderly flowers. Because each kind of jewelry has different texture and reflective characteristics, the demand for light distribution is also different. General lighting tools include tracing paper, black and white, gold and silver reflectors, spotlights, soft boxes, etc. to meet the shooting needs of different jewelry.

A. polishing of diamond jewelry:

The characteristic of diamond jewelry is that many cutting surfaces are formed after diamond processing. Under the irradiation of light, these cutting surfaces reflect countless lights, which will make the diamond shine. If you want to shoot such a brilliant effect. In light distribution, we should choose the method of supplementary light to produce brightness of different faces and highlights of different edges, so that each edge can produce clear light. But if he wants to completely eliminate the reflection on the jewelry, he can use tent lighting and build a "tent" on the top and around the jewelry with seamless paper.

He should not only cover the periphery and the top, but also cover the front, and then make a hole in it so that the lens can be inserted for shooting, but the hole is not too big, just enough to extend into the lens and light. Sometimes the light is just outside it. Soft indirect lighting of the tent. This will make the light uniform and will not cause unnecessary reflection on the jewelry. Figure 1 What we see is a tent-type light distribution method, with uniform light, and the front diamond and the side diamond have adopted a shining effect, giving full play to the reflective effect of each cut surface of the diamond.

B. Lighting of gold and silver jewelry:

Gold and silver jewelry should be colored to achieve the golden effect. The shooting of gold and silver jewelry mostly uses direct light. It is also necessary to use various small reflectors, including gold, silver, black and white reflectors, to fill the light at a specific angle to highlight the firmness or roundness of the surface modeling of gold and silver jewelry. The gold bracelet in Figure 2 focuses on the beads of the bracelet, and the whole picture is soft and delicate.
