This is a slightly mind-bending panorama that you really need to view as large as your monitor or screen will allow. Click on the image to open it in the lightbox on WideEyedInWonder, auto-sized for your display. It is just about a full 180 degrees. You can see two ends of the same straight rail sticking out about 1/6 of the way in from each corner. Though the perspective looks natural when stitched together like this, you would have to relax your vision, or at least your attention, to see this in real life. It could be done if you are one of those people who can process your peripheral vision without falling over. 🙂

It is 4 fames, each frame an In-camera HDR, stitched in PhotoShop Elements 11’s PhotoMerge tool, and then final processed in Lightroom. I shot it off my Fat Gecko walking-about tripod.

Canon SX50HS. Four overlapping  24mm equivalent field of view frames. Recorded exif: f8 @ 1/500th @ ISO 80.
