We did a rehearsal two days before the final seminar which was Wednesday night, because of the main idea of the seminar is ‘the United Nations’, so that we bought a lots different countries flags and decide how could we put them would be the best way when camera shooting. Also we have to figure out how to put the sofas, coffee table and host’s chairs due to we have four guests and hosts, it was take a bit time. Then I helped Vicson to set the light and finally we decided to use one key light  on the side of first roll in the theater and one back light on the back side of the host’s chair.
