First off, just one that I liked for the minimalist nature of it:
Despite what it looks like at first glance, this is actually not a B&W treatment. The actual wall was slightly darker as well, but the GR3's exposure program decided that it should be a bit more towards grey than black. Though I still did darken it slightly, I can't really complain as it makes the bricks more visible.
And secondly, my originally intended shot, since I had no idea what else to shoot. Processed with Silver Efex's high structure preset, which I generally avoid.
