I found this wall of plumbing parts in the farming tool shed at Green Gulch where I was leading the Tao of Photography workshop. To make the image I shot five exposures with my camera on a tripod, which I combined in post-production using Hand-HDR in Photoshop and HDR Efex Pro 2 from Nik Software.
Even though I tried to position the focal plane of the camera as parallel as possible to the cabinet of plumbing parts there was a parallax problem. The parallax issues were considerably mitigated in post-production using Photoshop perspective transformations so the image would appear “all squared away” (the title is in homage to the Gary Larson cartoon with this caption shown here in a physics textbook).
