1. １． mi-ma-mo （ Focus on the finger-rest contact points in the mouth ） ① y dimension: Set the camera at the midsagittal plane of a patient or a sim head. ② Use a stick like a sliding aerial to decide the direction of the camera that covers the finger-rest contact points （ mi-ma-mo). Reference conditions for photo taking of 20 items in kb3 ③ Set the camera to the direction of the aerial. ④ Take the aerial away and click the shutter.

2. ➄ Include the end of the instrument held by the right hand in the shooting range ⑥ Make sure that the directions of the mirror surface and the handle in the left hand is clearly seen. 2. Photo of the side view of an operator’s upper body ① z dimension - Set the camera at the height of the operator’s shoulder. ② x dimension – Set the camera parallel to the midsagittal plane of the patient. ③ z dimension – Range from the top of the head to the thigh. ④ y dimension – Range from the back of the operator to the chest of the patient.
