i need to fly in from the middle of the room on my little mini "steadicam", about 6 feet to the door, where a character will crack it open and smile like a maniac.
i'd like to avoid being out of focus until arriving at the final mark in front of the door. i have no fancy FFocus, BUT what if i videoed in deep focus, deep enough to have a few feet DOF?
Wouldn't i need to add a certain amount more light, then close the iris a certain amount to keep the continuity of lighting between these shots and the other shots not in deep focus?
First of all, is this correct reasoning? If yes, i can be in focus the whole journey to the door, where of course i'd rather rack focus if i had the tools.
If i'm right, how can i use my new sekonic L-478D meter to help me measure how much more light, etc?
