Getting up close and personal with the iconic St Louis Arch makes you appreciate a few things: not just how how big it is or how well little hand prints show up on metal, but the textures of the metal, how each panel catches light, and its amazing swooping architecture when set against the thin high clouds. Positioning was the hardest part here to compose the shot. Other than that, aperture was set at f/13 to avoid focus stacking. I can't describe how awkward a position this was.
Settings: 18 mm (27 mm on 35 mm equiv), f/13, 1/60 s, ISO 100
