I am an audio neophite, but I am going to shoot a documentary in a high-security prison and will be unable to bring a "soundie" with me on the shoot. The area that concerns me most is shooting a round table (no real table, just sitting in a circle) discussing with 8-12 inmates. As you can imagine, it's hard floors, hard walls, hard ceiling. I'm shooting with an HVX200. Should I use both a shotgun on cam and set an Oktava MK-012 on the floor in the middle of the circle? Any suggestions from guys who know what they're talking about is better than me guessing! Thanks for all input.
