Streaming video. Two identical setup at the teachers and students end and Zoom as the string in between. Different situations, different problems. The organ lesson - lighting my face using a ring light from the front whilst illuminating the keyboard from the side to get better depth and videoing from overhead using a jib, and also using a pedal cam and light on the feet. In addition since this is all a two way process the situation is mirrored at the other end so the lesson can take place over zoom. The sound needs to be transmitted well with a good two way conversation happening.
