Re: HMI and Green screen

I also found that adding green gel actually gave us a better key.
I shoot with an HDX900 .... and its shoots beautiful pictures so we make it work for the green screen stuff. I'm be curious if anyone else agrees with that.

I agree with you Mark. The 900 shoots beautifully. Normally I never add green to the light on the greenscreen. When I have, it was only because I had LOTS of distance between it and my subject.. or I had a shoddy greenscreen material.
My preference is always to "warm-up" the subject (with either minus green, straw, bastard amber, whatever works best) to separate him/her from the screen. This helps minimize the green bounce "light source" that trys to "tear" my subject away from the foreground, while changing the quality of the light on the subject -- as opposed to the greenscreen.
I always have the greenscreen at least one stop underlit.
Many of my lighting decisions are based on how big the greenscreen actually is, whether or not my subject is also walking around on it, and what type of lighting instrumentation I'm stuck with.
If I'm just doing a simple head & shoulders greenscreen shot I would light it very differently than an entire virtual reality set. Every situation brings with it it's own set of problems.
