Hi, Im going to be shooting a scene which invloves an actor in a green screen studio, who will be composited into a CG environemnt where lightening is flashing in through some windows high above. I am a student so have various Arri kits at my disposal (tho don't think we have HMIs). The studio also has controllable lights installed (kinos I think?). Colour temprataure doesnt bother me too much as the film is graded to an almost Sepia tone. Shooting HD.

Im looking for advice on how to make the flicker of the lightening....in fact it doesnt even have to look THAT realistic, it could even look quite expresionistic...I just wanted advice on how to make a lightening flicker that looks decent.

many thanks :)

For the most part, Lightning choices are:

1. Lightning Strikes

2. Arc Plunger

3. Shutters

Considering your available Lamps... Shutters.

p.s. You (may) consider adding a bit of Blue (i.e. 1/2 CTB) as Lightning Strikes (tend) to be a bit cooler...

Enjoy your shoot!
