Hu Guys,

I am almost der with my chroma keying project and I have shot behind a green screeen and all that stuff.

Here is what I am doing, in the background I have a white graffiti wall on with I have written some witty one-liners and I have made that image using Adobe Photoshop.

When I make the green color transparent it works like a charm but as the background is white my black hair has some shine on it.. I mean u can see white spots u know.. and its not completly black.

When I change the background image to say Blue its fine my hair is perfect and ofcourse black ground works the best.. I hope I am clear as to what My problem is, when I have a white background the darker shades have s**** spots on it and does not look natural.

Is there a way I can fix this without having to change my white background?

It's probably a lighting issue. Some of the green screen may have been reflected back to your hair. Now when you key out the green it is also keying out some of your hair, thus the white spots. The darker color backgrounds may not not be as easy to see in your dark hair.

How far away from the green screen were you?
