Wow. So about ICE? I assume that you have tried GradientMergeMosaic and you are convinced that ICE is nicer (sorry I had to do that)?

Sometimes I use ICE, Photoshop, or PTGui for mosaics. I’ve actually never tried GMM, I’ll mess around with it and see how it does. I’ve just always had good luck with ICE and it’s easy to use.
