This is the beautiful Cataldo Mission in northern Idaho. We passed through this area on our way to Yellowstone in 2009. I loved the texture and color on the ceiling and the floor.
This HDR processed image is slightly cropped down from the original to 565 megapixels (4x~11x3). I processed bracketed sets into HDR files with Photomatix, stitched with Autopano Pro and then tone mapped with Photoshop. I couldn't get Photomatix to tone map an image this large.
