I have the pleasure of being able to record a gun (powder charge only) being fired inside of a large concrete room. I have read a lot about shooting outdoors from Chuck Russom, but I'm wondering if there is anything specific I should look for inside.
The other thing is I have only 2, maybe 4 inputs to record the effect. This is being done on the tail end of an ADR session and we're just going to get what we can in the spare time after the actors are done. About 90% of the SFX needed were recorded on site, really all we're missing are punches and gunshots.
I have a Schoeps MK41, AT 897 shorty shotgun, 2 AGK small capsule mics, and a few contact mics that I've made and coated in handle dip. I may be able to ask for a few more mic rentals if I can justify them.
I was thinking of one of the AKGs near the gun for the initial shot, the Schoeps about 20 feet out to get the distant perspective, a contact mic directly on the gun barrel, and one more AKG maybe 12 - 15 feet out from the barrel.
Any thoughts would be great!
