Yeah I'm not sure exactly what the issue is yet, but I'll play around with it a bit more. As can be seen in the crop I posted above, it looks ok in the colour data, and looks even better when stretched more, but when combined with the super lum something weird happens.

I'm also going to try and get some more data tonight so maybe that will help (assuming my hardware plays nice for once, a rare thing!).

It is a very fine and subtle image Lee. Agree with Mike that a bit more green might give more "normal colour, but even so, the enhanced background structure adds a lot to the overall effect. Like it a lot. regards ray
Thanks Ray! I'll have a another crack at the colour.

Cheers Paul! Consensus is definitely that it needs more green. I'll give it another crack. Of course I no longer have my working images so it'll probably come out completely different this time
