Unmanned Spaceflight.com _ Image Processing Techniques _ Processing Pioneer 10 & 11 images

Posted by: Fox Jan 6 2020, 05:25 PM

Hello, I'm new to the forum but I can see there is plenty of great information here!

I've just begun to experiment with processing some scans of Pioneer 10 & 11 photos. I've taken the Red channel and Blue channel into Photoshop, but what would be the best way to create the "synthetic" green channel that the books mention? Any advice on how to go about this would be appreciated.

Thanks!

G = ( R + B ) /2 for starters.

That's where I started, but my image seems to come out way too blue. :-( Maybe my scans are to blame.
