Old suggestions: white+exposure, black-exposure, generally+1 or -2.
Adjust the manual white balance before shooting, because the light may be off color. If you use RAW, you can adjust the color temperature later.
In addition, it is best to match a reflective plate or display shelf, and the effect will be much better.
If it is a black background, I suggest you use 2 lights, give up the top light, reduce the exposure by -2, and adjust the aperture to F 10.
ISO can be adjusted to 200, and the shutter is controlled around110.
It is suggested that the shutter of 1 picture should always be kept at a similar value, and the post-processing will be better by adjusting the exposure compensation.
