This is a fascinating location for High Dynamic Range photography. This image required blending 5 separate exposures together to render all of the light and dark tones. Once a barge coal dock in Philly since the '60's, it is an abandonded massive concrete structure stretching several hundred feet long along the water front. The graffiti art is continually painted over with new art so each visit reveals something new. The "rock" or large chunk of concrete in the foreground of this photo I have been accredited to have found by pro photographers who have visited there many times. I "found" it in one of the corners of this huge complex.
