Thanks for that info Casey! I did not want to pay for a new version of Calman as I can get around 3.5 pretty quick. I'll check out Tom's software before I move to another version of Calman. I've been using Calman since it was in an Excell format.

Argon - If you like what you see, stick with it. I like accurate colors, flat grey scale and a progressive gamma. It's no different that audio really. If you like tone controls, use them, if you want accuracy, well I don't to preach to the choir.
