Hi, just wondering if some one could help me. I only know basic expressions so hopefully this is not too complicated.

I have footage of a LED wall with graphics moving and flickering on and off mostly black and white.
I 'm placing a person in front of the LED plate shot on a green screen already keyed out, and want to match the lighting conditions.

Can I use expressions to animated an after effect light intensity with the luminance of the the LED layer..
