Nikon D3S, what should I pay attention to when shooting jade pendants and rings in a small studio?

It's best to use a hundred micro-shots of these small objects, but the fuselage is not important, just the entry machine.

Generally shooting in manual mode, the aperture is around 8- 1 1, ISO 100-400 is ok, and 100 is better. Then adjust the shutter speed and light brightness until the exposure is accurate.

You'd better put a tripod on the camera.
