It turned out that it was York Northern Pride 2012, I had with me my Leica M8 so took the opportunity to take a few shots.
Processed in Lightroom, some cropping and levels adjustment but not much else.
I used the Elmarit 28mm for most of these, a couple were shot on the Voightlander 15mm.
Those those of you who are interested, the photo above is cropped from the original dng file. When I view the original dng at 100% I can read the newsprint on the front page. remember that the Leica M8 is "only" 10Mp
