Thanks for the replies. I do shoot in NEF to capture all the available data the sensor can record. It didn't dawn on me until Ed's reply, but I have Perfect Resize as part of my OnOne software package I bought a while back. I've never used it, so looks like I'll be testing it out soon. Its says it uses the Genuine Fractals algorithms. I do have a graphics place down the road that does this type of work so ill go and see if they will give me some pointers on what they need to make it happen. I'm also well aware of wanting the new body after renting it for a few days. I've never really done well with giving new tech back, that's pretty evident by looking in my camera bag(s)...and credit card statements.
