I got to hang out on set for a commercial shooting for a famous ice cream brand. It was cool to see all the different people, equipment, and such are needed for filming. The room was full of different people like production, brand agency, talent agency, ad agency, food stylists, etc. It's insane because the commercial is supposed to be a couple series of 30-second ads but filming took the entire day to shoot. Nonetheless, I learned a lot even just from watching and I got to see a famous Japanese model/actress on set.
