Believe it or not, the rushes were digitised using jpeg compression!
Thanks for advice. I will try two instances of Keylight. Looks like I wont be able to avoid masking though as there is a lot of near black in the dark blue halo. I tried turning up blue saturation, but the blue spill on his shirt (and not just on the edges – all over) is being keyed out.
I wish there were postproduction people supervising these shoots.
At least it keeps me in work.
Thanks again Dave.
Steve.
