Taken at a jazz evening at Papa Cinos in Northampton. No digital manipulation of this one. To set the scene for the technical difficulty of this shot. I was on a small table in a corner. The camera back was pressed against the wall in order to get far enough away from the glass so I couldn't use the view finder. I was on manual focus to get the glass in focus, so guess work was needed. Then to get the entire glass in required very careful positioning on top of my iphone and my wallet (I can't tell you how many photos either don't have the top or the bottom of the glass).
