When I bring up ADR with some of the local filmsters who rely too much on the built in mics on their i-cams, they act insulted.
I'm an editor, and had a client tell me once he wanted a scene to sound intimate and gave me an example from another film as the scene I had cut didn't have 'the right intimate sound to it'. I had to break it to him that the scene had better recorded audio because it was ADR not field recorded and his eyes bugged out. I said we could do it ADR if he wanted but told me no as they didn't have the budget and later complained that it still didn't sound intimate enough.
I actually tried doing ADR this past spring for an acting gig I'd had last summer... The director couldn't get the lavaliere to work, & lost the pole to his boom mic & was too good to try clipping it to a broom stick, & his sound girl was shorter than me....
Then, rather than call me in for ADR during principle production like he did everyone else, he called me & one or two others back some seven or eight months later, long after I'd forgotten my thirty second part.
By then, he had managed to get some nice high tech closet space a some center for the hearing impaired. Problem was, I had a cold at the time, & felt very uncomfortable being locked in a closet with someone else.
I'd never seen any of the footage before this, & should've asked for a few days to rehearse...
I also have ADHD & Aspergers' & asked to see the clock so I could better sync what I was reading with what I was saying on screen.
After about forty-five minutes, with a few breaks & sound checks in between, the director decided to go with the live audio he already had.
I was pretty embarrassed.
That's just one of many reasons I want to accumulate & master My own equipment.
