Hi Simon,
Glad to have helped a bit! I learned a lot as well from George, and learned about yet another piece of advanced software. I agree, Simon: the turbines are a part of the place and ought to be kept. And George: I LOVE Niksharpen! Nik sells a complete suite of their goodies for some $500 (which I'm not ready to buy), but I'm going to contact Nik to see how their stuff fits in with a CS2/Olympus setup. They made no mention of their software being either Nikon-specific or RAW-specific.
Cheers,
Leonard
