While sorting through my images from last fall I came across this version of the setting of the first concrete form for the north tower of the downtown span. I liked the composition and decided to try it as a monotone image. I used NIK Silver Efex Pro to convert it to monotone and applied a preset for an antique feeling. I then sent it back into Aperture 3 for final processing.
