Gotcha. By the way, be as heavy handed as you want, I'm thick headed :)

Is it my imagination or does the ideal saturation change depending on the other values I've

set, or once I find the ideal saturation for that camera is it always the same?

Thanks.

I just wanted to add in my prior issues with the color unibrain and

the red-gain...

Not too be too heavy handed here, but it was the Saturation control

not the Red gain that caused it. This only applies to the low end

inexpensive cameras have the Saturation control. The way Saturation

is implemented is that it uses a convolution algorithm in the

TSLBV1501 chip set and it doesn't work very well, except to increase

noise levels.
