Topic: lighting for green screen

I am trying to get into green screening.  After some research, I bought some green paint (flat finish) and painted a wall.  Then I began to set up lights.  I have two 500 watt lights mounted on a rack.  These are halogen work lights.  Then I bought a 500 watt floor halogen light.  I focused the two 500 watt lights in front on the far side of the room and faced the lights towards the ceiling.  Then I took the floor halogen light and moved it out about 36" from the green wall and shot it up at the wall.  To test it out, I had someone stand in front of the green wall, in between the floor light and the lights on the other side of the room.  I was still getting shadows on the wall behind the person.
Does anyone have any good tutorials on how to do this?

Have you asked your local friend Google or his friend Bing?

I haven't done much with green-screen, but I'll be working on that more in the future at work, but I can give you some quick tips from what I do know:


1. Make two zones of light: One for the green-screen and one for the actor/scene

2. Evenly light the green-screen with soft lights (ideally) and hit it with a lot of light.

3. Make sure that the green-screen light doesn't spill onto your actor/scene. You want all of that light to come from the second zone. You can make flags to direct the light.

4. Light the actor/scene however you would normally.

5. Of course, make sure you don't have any green on your actor/scene, because it will disappear when you work in post-production.

Re: lighting for green screen

I'd actually add to Cinexcellence comments by adding another light to your greenscreen so you have 2 on your screen at either side to create a nice even light and then 2 on your actors and set (difuse these with paper so they're not too strong).

As Cinexcellence has said though avoiding the green spilling onto your set is one of the keys here as you will have a nightmare in post production so I'd have the screen a good 3 feet away from your set to avoid this.

Also what camera are you using.? The only reason for asking is that if you're using a web cam keep the exposure high and the gain as low as you can go to avoid any unwanted grain.

Hope this helps
