lighting green screen

We had two locations for green screen. The first one was for inside the space craft.

for which I lighted the actors for f8 key light. For back light i used magenta to cancel the green on both the actors and the set peace.  I lighted the green screen as f11. Three stops over. 

The second location was for cave scene and crash scene. 

For crash scene i used three point lighting as the sun as key light. 

For the cage scene I used only one source. One blonde coming from the top. 

I used dido to lit the child actor as she was not getting enough light from outside lights.
