I'm going to shoot a scene in which two actors are outdoors on a not very noisy city street. The actors start out about two feet from each other and then move in slowly during a conversation that ends with a kiss. I will boom it (MKH-415) and have each actor wear a wireless lavaliere (TR-50). If it doesn't come out well, I will do an ADR session, but I'd like to avoid that. I'll be recording on an F8 to separate tracks for each microphone. Is there any advantage to recording one lav with the phase inverted? All other tips welcome.
