I have a Jinbei flash studio camera d3 100, and a decorative background for shooting ceramics.

I also shoot ceramics. Your set of ceramics gives me a sense of confusion. The lighting is too hard (is it three-point lighting? ) The spots are too big. The pattern of ceramics can't be seen in that glaze color. Did you shake when you took the picture? A little shaky.

It is recommended to fix the house camera with a tripod when shooting, and change the background into a gradient, one at the back left, one at the right front and one at the front left slightly (the effect is not obvious when shooting, and the ceiling lamp is added). The intensity of the light should be lower (you can see the effect you want to shoot). Adjust the ISO under the shutter according to your own light, or watch the camera adjust it slowly.

Try a few more times and you will get a good photo. I wish you success!
