Martin,

Followup:
I made a small "C" exe for the PC to correct the green channel. Right now it's just in dos and only works on small
bmps (< 64K.)

what I started out with is on the left.
what I ended up with after simply taking the G value and
making each green value it's inverse(G = 255 - G). it looks like it works ok according to the thread. The upper image is your
image from gillans thread for comparison(so it's all on the same page. (if you have any objection to the image being there let me know and I'll delete it and repost an image sans your image.)

What do you think?
