It's fascinating to see which things are predisposed to remain, and which to be discarded in the fabric of a city. Isn't it amazing that pavements always seem to stay the same, be they unfeasibly large or unfeasibly small. It's something that always goes through my mind when I'm wandering through the older parts of London. Railings too seem to endure, a fact much noted by Brits who are accustomed to seeing little iron stubs on the walls in front of their terraced houses, a relic of the metal removed and smelted down to produce steel during the Second World War.
There's also an interest in seeing what it is that the takers of the original photos sought to cherish by taking photographs. Often, the buildings which inform the subject of the new composition are very much the backdrop to a fancy car or a loved one on a bench.
Hopefully, however, not to become another one of those all encompassing flickr crazes for photoshopping crap into other crap to make more crap.
