Wow.
That is a great photo. It almost looks like a film set from one of the moody British films of the day. I have a tendency to scan (or shoot digi) scenes and post-process too "light" - something I'm trying to eradicate as, if it was taken in the dark, it should look authentically dark.
This photo has light that is perfectly balanced between the external pub "lamp" which lights the building and the figure and the light emanating from the pub itself - which suggests that the figure is isolated (or is isolating himself) from the crowd indoors.
I love the shadowy buildings in the background. Just enough light to see them but dark enough to leave them mysterious.
I wonder if the location still exists?
