Excellent photo but still don't understand how he keeps the reference points so exact while the photo is being taken. Might be possible to build up multiple shots in a stacked image, that way you could play around and stack the best of the best traced images. The alternate method I though of was that the people and chairs were there, everything was black and the light was traced around the objects while there were there.
