The interior of the Basilica de Notre Dame de Fourviere, Lyon. Personally, I find the two people who were quietly taking in the serenity make the image.

Wide-angle panorama stiched from 3 images, each image exposure bracketed +/- 1EV. Each stitched layer then merged using Photomatix Pro exposure fusion. Some Lens Correction applied in PS to fix the verticals as best as possible.

Canon EOS30D, ISO640, EF17-40mm F4L @ 17mm, f4, 1/30, handheld, no filters.
