Thanks quite Ok Martin, I was once a newbie too (I'm still probably not that far ahead of you

).
I capture my images with a DMK 41 which is a mono camera. You are correct, the colour is artificially applied during post processing. There are lots of ways to do it, but the method I prefer is to adjust the
output of a levels layer in PS. To gte the colour I use, I drop the blue output to 0 and the green to 150.
