How do they take such photos? With such a long exposure, shouldn’t everything “blur” completely? And if the photographer (Vyacheslav Prokofiev) allows himself to use collage, then it isn’t really photography anymore, but “Photoshop.” Therefore, I suppose he does not allow it. But how then is it done?
UPDATE: It seems like a long exposure in the dark + lighting with spotlights for short periods on different parts of the hall. The photographer is awesome
