Does the size of the object matter? Is smaller better?
As long as an object or artifact fits on the turntable or pedestal, can be anchored securely, and can be rotated without changing position, the size of the object does not matter. Smaller is not always better because small objects often do not have the same kind of detail that larger, more ornate objects have. Your camera tripod and lights may need to be moved (forward or backward, higher or lower) in order to accommodate capturing images of different sized items.
