I was thinking that just the other day, although I'm not sure you'd want to take the time to work as slowly and carry as much weight and equipment needed to do that. Still, there have been several photos of yours where it was clear that a 4x5 would have provided better results.
I was disappointed in the quality of then16x20 you showed us when we were down in San Jose. A larger format would have made that print really "shine." In truth, you're limited in the size and quality of the print you can produce with the istD. IMO, unless you start working with a larger sensor and many millions of more pixels, or a larger format film camera, you've just about reached the limit on what you can do with your landscape photography. Some of your 'scapes should be seen BIG ... of course, you can get into stitching and all that entails, but I think you're about ready to move up a notch or two, become a little more contemplative and deliberate in your work, and start producing photos of truly "monumental" proportions.
