I'm filming for the first time in a studio for a few corporate talking heads videos, and I'm after some advice on how to light it properly. We have 3 x 800W Tungsten Redhead lights (3200 Kelvin) that we are going to use in a 3-point setup (as key, fill and back lights). The studio does not have a ceiling lighting rig, so the lights will be on floor stands. Is there anything special I need to know about how to light it properly? Anything different I should do compared to when I'm filming in any other normal room? The studio will have an "infinity" white backdrop. Here's a photo of it: http://postimg.org/image/5iuexa6rn/
Another quick question - I assume it's really bad practice to "mix" colour temperatures from different lights? In other words, I assume I should turn off all other studio lights when filming, and only have the 3 Redhead lights turned on? So the "stage" will be lit up but the rest of the studio will be dark? So then I can just dial in the white balance on the camera as 3200K, and it will then be balanced correctly for the Redhead lights? Sorry if that sounds like a stupid question...
I hope someone can help.
