Some people have this misconception that film production somehow means "have camera, will shoot." A production company is not a videographer, a one-man band, or a lone person self-styling themselves as a filmmaker. Film production, like most businesses, has a lot of facets. There's the obvious stuff, of course: knowing lighting, composition, and that just so angle for a shotgun mic that makes will record audio. It's knowing the difference between 4:2:2 and 4:2:0, and how to craft a compelling story. But it's also a business. And, to make everything smoothly, there's IT.
