When I use the chroma-key eye dropper to pick the background color (green) I get the expected effect and I am able to use the intensity slider to adjust the transparency from zero to a point where even the wanted image is affected.
So far so good...
However due to minute variations in the lighting intensity of the backdrop I get speckles and other errors in the final output. The more imperfect the lighting setup, the worse the speckling, so I know its my lighting at fault, not the software.
My question is - Is there any way to obtain a broader value for the chroma-key (maybe by adjusting a value in the windows registry for the chroma-key function??)
In other words make chroma-key dissolve darker-green and green and lighter-green colors in the video data not just the single color tone chosen by the eye dropper..
I have scanned the internet and see other more expensive packages offer a band of color adjustable around the color picked.
FYI I am using six tungsten pearl floods to light the wall - all purchased in a single pack so I assume they have the same color temperature. My main subject lighting is a halogen flood.
