Photography of metal objects

A very difficult subject. I personally can't talk about experience. Here are a few points to pay attention to.

Aperture selection: large aperture can blur the background and highlight the main body, reflecting the sense of exquisiteness, but the disadvantage is that the effect of light will be scattered; A small aperture can make a star, but in order to highlight the main body, light distribution needs to be more careful. The two have different effects, so we must weigh the advantages and disadvantages. Large aperture shooting, macro lens is recommended. Depending on the specific situation, a polarizer may be needed.

Background: In the case of matting or simple display, use a solid background. In the case of theme advertising, in principle, silk, sand, stone and other "texture contrast" items can be used as backgrounds or props. In addition, you can also consider taking the model and its limbs as the carrier for shooting.

Light distribution: Because it is a reflector, it is necessary to frequently use black cards and shading strips to control the light band of the main body, control the light level and avoid unnecessary reflection. Small aperture shooting needs to introduce profile light. If the model or its part is used as the carrier, we can consider using beam tube honeycomb to distribute light separately. In order to reflect the texture, matting agent should be used with caution.

Focusing photometry: in order to avoid the influence of light spots on the object on focusing accuracy, pure manual focusing mode should be adopted; It is also suggested to add and subtract exposure meters instead of in-machine metering.

As for the importance of the later period, I will not mention it here. Not the director for reference.
