We are shooting a new commercial that needs an infinite white background.
I did lots of searching online and did find a couple great videos about it, these sum it up pretty good:
Unless I missed it there was a little detail missing, probably because I'm a novice.
Our original screen test looked like this:
Definitely not white, I did some color correction, but this is where I ended up without over exposing him too bad.
So, following Olivia's instructions worked and the part I had to figure out was to turn the light way down on the talent. I know it's lame but that's the part I was missing.
The key light and the fill light are the 9 Bulb Octacool's so I turned off all but 2 light banks on the key light and left only 1 bank turned on, on the fill light. We turned off 1 bank of the hair light.
So once I did that I could expose for the talent so that the background would be blown out.
We are still tweaking it, we had two of the 9 Bulb Octacool's on the background with the diffusers off.
My camera settings ended up being:
camera: 5d Mark III
lens: 24-70mm Canon L Series
shutter speed: 50
I used the cinestyle profile and in Adobe Premiere I added 30 for sharpening and 30 for contrast in the brightness and Contrast effect. Less workflow and tweaking than I had to do for the previous video trying to get it close to white.
This left the talent a little bit over exposed but looks really good. Next round I'll pull the key and fill lights back and get it perfect.
