Howdy
If the sky was darker Id not have needed to stretch the levels as much, I think thats why the images are a bit grainy. I might have a play with noiseware later on to see if it can smooth it out a bit.
Did a lot of fiddling to coax the detail out. Iris has this "white" function where you draw a small rectangle over the sky background and it automatically brings it to a neutral colour balance, its very handy for modded DSLR's
I can only imagine what we would have got had we been at Kulnura instead
