Thanks David! I'm looking for more of a hard sunlight effect keying the talent (with maybe 1/4 grid) rather than a soft light key- although I may push it through shears. I'd probably shoot 800 ASA at a T2.0 to T2.5 range. Window is just your typical 2.5x5ft household window. Probably daytime with no direct sunlight to the window, just skylight. I'll link to an example of what I'm looking for. https://vimeo.com/121040557 The bedroom scene in the beginning is similar to what I'd like to achieve. (Credit to Steve Annis as DP for the piece)

I'm curious on what kind of output would be necessary to key from a light outside a window into a small (10ft x 12ft) room for a daylight interior setup. This is assuming no direct sunlight or night. Do I need a 12/18K or can I use something like an M90, M40, or even something of lower output?
