How to shoot 925 silver ornaments on white background? Either the bottom is not white enough or the theme will be exposed when I shoot it. Please tell me the complete scenery, stage setting and lighting details. Cover the soft lampshade with two small lampshades (just cover the lampshade with gauze), and then sidelight one on the left and one on the right. Pay attention to adjusting the angle and don't leave shadows, so that the brightness of the whole background is more uniform.

ISO can be lower than 400. The graininess of 400 will be stronger than that of 100. If you need fluency, use 100.

Please aim at the ornaments and use spot metering, and then lock the exposure value with the exposure lock.

First, remove the ornaments, shoot a white background under the same exposure value conditions, and set the photo to a custom white balance.

Then put on ornaments and shoot with the same exposure and defined white balance.

If you feel that it is not ideal, you can use the defogging mirror function of isee photo experts to enhance the contrast, and the exposure repair function can imitate the surrounding exposure synthesis, making the color of jewelry more delicate and full.
