I like the transition from light to dark (or dark to light) in the upper part. The grain shows well here and I like how the intensity changes as black becomes white and vice-versa. I think this is balanced by a more abrupt transition at the bottom where black becomes white in a far more definite way. This is my favourite part. The vertical and horizontal lines give a nice feel of uniformity of structure and I think this works well against the slightly fuzzier reflection. I see this more as an abstract than an architectural study, the title maybe a little misleading, perhaps an explanation can be offered? I like the picture, it's something I probably would have taken in the same way. I'm sure it looks much nicer on the print than on my screen.
Photography, the word itself, invented and defined by its author Sir John.F.W.Herschel, 14 March 1839 at the Royal Society, Somerset House, London. Quote "...Photography or the application of the Chemical rays of light to the purpose of pictorial representation,..". unquote.
