Wall At Graveyard

This is a wall at a graveyard near Stockport College, i took this picture with a canon 550d with an 18-55 mm lens, i then took the picture and put it on photoshop were i edited it to make the patterns in the wall stand out, i also made the photo black and white so its easier to see the definition between each block. I took the photo at an angle were there wasn't much light so i could see the difference between the pattern in light and the pattern in dark.
