I found lav mics to be the best and worst things when shooting entertainment. I love them for close up sound, the versatile wireless set-and-forget functionality and dynamic range, but the few ways I knew worked for hiding them were sometimes problematic and usually awkward. Usually it involved some method of taping the mic to the inside of the actor's shirt (which you could usually see the tape from the outside) or right to the chest of the actor (I've ripped more chest hair off of strangers than a first-year esthetician). Then, of course, when working with performers of a female persuasion, I get all stammery and sweaty (not because of any problem on their part, they're always pros) but where else would the best place to hide a lav mic on a lady be, than... right... in.. front?
I look forward to having a better relationship with these little sound ninjas in the future! Thanks fellas!
