Last year, I visited Washington National Cathedral to shoot some panoramic interiors. I recently restitched them using some new techniques. I think they turned out great. The following is a set of 4 panoramas, all of which were stitched from the same set of 117 images. Two of the panoramas face the sanctuary and the other two face the nave. One of each is cropped at a 1:4 ratio and the other at a 1:5 ratio. The 1:5 ratio crops are 360 degree panoramas and you can see how the edges line up with each other. Click on an image to see it full-screen.
