Jeff, Lovely B&W park image. I can image the tonality could be adjusted in a number of ways for this particular image...as I'm trying to get a visual of the various possibilities (looks) in my head.
Princepollux, stunning images! As others have expressed, I'd love to see these printed large/wall mounted. In the last pano you posted, I felt there was a slight bit more post processing than I might have wanted...not sure if it's just the colors pumped up a bit or what looks like a mild HDR effect. Regardless, this is just a subjective comment on my part and the images are truly impressive.
