On past shoots, I've used boom operators, but I've never hired a dedicated sound guy. Someone with a field mixer, etc. I'm wondering if it's worth the money. My audio experience is average to slightly above average. I know which mics to use in which situations, and I own a pretty decent mic spread (a shotgun, an Omni, a hyper, and a couple lavs). My results have been mostly positive. I monitor the audio feed on a pair of headphones through my camera (a Canon C100), direct the boom operator as needed, and generally get clean audio. Inevitably, I've had to perform ADR on occasion, but I've always gotten decent scratch audio in these situations. In post, I've been able to mix my audio to satisfaction within Adobe Premiere. So, again, my question is, what am I missing out on by not having a dedicated audio guy? What can they offer that I can't fix or address in post? Most of my shooting experience has been in the narrative short, documentary, or corporate vid realm. I might be shooting a low budget narrative indie in the near future. What should I be looking for if I decide to up the audio ante?
