Attached, my unscientific ( tweak till looks nice ) method for taking the IRB images from the IAS viewer ( with all channels set to be unstretched at 0 to 255 ) and making them look a little more 'normal'.

If you go to image > adjust > channel mixer - you should then be able to load this, and it'll have a stab at it.

This is a bit better than the one I used to do the four avalanche images - I'll revisit them in a bit ( edit - now done, they look MUCH better )

If anyone knows a more scientific method for the artistic types, chip in

edit: this only appears to work for that image - that polar image. The ice providing, I assume, a white point.
