It's not the camera, it's the problem that you ran out when you couldn't shoot the jewelry. Photography is called "light painting" in Japanese, which is vividly interpreted as painting with light. Therefore, if you want to make the diamond shine, you must use a high-brightness spotlight to illuminate it, and adjust the illumination angle and distance appropriately so that the light can be refracted into the lens. Black velvet can be used in the background to avoid stray light interference and highlight the main body. It is best to fix the camera with a tripod. The sensitivity does not need to be too high, otherwise the noise will affect the imaging quality. Setting the aperture priority mode and shooting with different apertures will have different depth of field effects. Use spot metering mode, or reduce exposure compensation by about 2 blocks. Try a few more times and you will get satisfactory results. Good luck.
