Calculating Soft Light Throw
Posted 27 February 2014 - 11:56 PM
I wouldn't mind a general answer, but I do have a specific setup I'm interested in calculating for if any one is able to help me.
I'm considering creating a flying moon about 20' vertical (bottom of the 5x5x5 cube). 4 2K Juniors pointed at opposite corners, the entire cube covered in bleached muslin.
I'm trying to figure out what my exposure would be directly below at head height, and what the maximum horizontal distance from the cube I could pull a 1.4. I'm slightly nervous I might need more power, which I imagine will be the case.

Hell it would even change often substantially with how recently it was last put through the wash. If you are going with one of those helium balloons, however, they may already have rough photometrics on it.
