I've recently been asked to budget a 1.5 million dollar feature for my camera department, grip department, and electric department. Even though I'm still waiting on a treatment and a final script, the production would like general numbers to help with their investors. I've worked with the director in the past so I know the basic style but the task of budgeting seems too great and vague to breakdown. To those that have worked on budgets of this size or greater, how do you break down the math in advance? I assume there is a general percentage of a shooting budget that typically is given to the camera, grip, and electric, right?
