Then a master photographer can tell me how to take good pictures of still objects.

You can shoot still life with a SLR camera.

First of all, it is best to fix the camera with a tripod. If the shape of the dish is not big, you can shoot it automatically in close-up mode.

You can also shoot in telephoto aperture priority mode. You don't need a flash, just put the dishes in a well-lit place.

The other is the angle. You can move your camera flexibly, looking directly from the camera, and it looks good from any angle.
