Does a chef's plating in Madrid absolutely need a tripod and a mirrorless camera?

No, the chef's plate is judged by the point, not by the body. A support helps so the sauce does not come out blurred, and it does not replace the chef being on the pass. Look at whether the point is recognised, and leave the camera brand out of the conversation. In Madrid the kit is discussed and the chef was not there. The series is judged by the chef's plating, not by the camera.
