Panasonic SDX-900, 24p, Canon lenses. A lot of effort is put into decently shallow depth of field and cinematic grading in post, according to my Google search.
I ran into a PA in vegas who had just worked on the show the previous weekend. They took 2 hours to light the club interior the show was shooting. Its presented as a reality show but it is certainly not run-and-gun.
I love my GF in spite of this show. She loves it. I cannot, for the life of me, understand that. I just let her have her guilty pleasures. She has The Hills...I have Cuddy from House.
