Farm Progress Agricultural Trade Show, September 1-3, 2009 in Decatur, Illinois, USA.
These were made with a M42 mount 28mm Wide Angle lens f/2 Vivitar lens. It was mounted on Canon EOS 30d DSLR and was not refocused between each of the 14 frames used to make this panorama. I overlapped by a lot more than 14 frames and then selected, hopefully, the best. I shot quickly as people were moving, which a few places you can see the resultant anomalies from the compositing process.
The first image is one part of the whole Panoramic photo:

Big photos. There is a celebrity or two in the pictures. Really!
