Topic: Dark and light bluish gray containing green?

Hi,

with a recent attempt at brickfilming I've encountered a queer problem. Let me describe it:

I used a (nice evenly lit) green screen and 4 lamps to light up the set. When I chroma-keyed a blue background into the video after filming, all the grey parts are incredibly blue! Whether it's light or dark grey, it almost seems like I used blue bricks when in fact there's not a single blue brick in the scene!

Dark red beside grey - pure dark red. But the grey - blue! And really, pretty much everything else has been keyed perfectly. But for some strange reason, not the greys.

I'm thankful for all your input!

PS: I will be able to provide you a link to the sequence once I set up a youtube account.

EDIT: resolved

What kind of camera are you shooting with? Digital? Webcam?

Re: Dark and light bluish gray containing green?

Well, the post-color change grey is often called bley for a reason.

I just had a problem with my blue bricks looking gray!!! mini/lol

Re: Dark and light bluish gray containing green?

Hey! I think I have stressed it enough that I'm using green screen, so bley wouldn't be an issue, right? I mean, it's not Dark Greenish Gray. mini/smile

Anyway, the issue pretty much resolved itself. Maybe it's just WAX, because After Effects gives MUCH better results.

Cheers!

^ Yeah, WAX doesn't work to nicely, no wonder After Effects produces better results. If you need to do more green screening, stick with After Effects.
