Re: Portable green screen

Considering the detail of your original post, everyone's silence speaks volumes.... although asking if a DIVA should be used instead of the 4 bangers belies your experience. Why not just use Image 80's?
When lighting a 12'-0" x 20'-0" nothing could be considered "portable". Why so high? Why not a 12'-0" by 12'-0"? Why worry about the greenscreen and not consider the very important talent walking in front.

Incidentally, with a 20'-0" high greenscreen I would light from the sides and overhead, or just double hang overhead to compensate for separate lighting for the top and of bottom of the screen.
