Funny you should say that. I belong to an artist association. Every year we have a juried show in our state's largest art museum. This year we were allowed to submit two pieces of work. I printed the iris shot 20"x30" on Epson Exhibition Fiber paper and framed it with AR glass in a 29"x39" frame. I thought it was quite a striking photo, the dpi is over 300 at that size. Well it didn't make it, but at least this photo did.

I should add that this shot is a panorama as well, taken with a 28mm lens, about ten shots.
