This is an HDR vertical pano of St. Francis Church in Porto, Portugal. It consists of 6 horizontal frames that were stitched together in Photoshop, and each frame consisted of 7 bracketed exposures. Once each frame was processed to produce an HDR image, I then stitched all 6 of them to create the panorama image of the church. The final composite is very sharp; I can enlarge this to show a tiny ceiling detail that looks surprisingly sharp. I used tungsten white balance, and every frame was handheld. Before all layers were flattened, the image was 2.3 gigabytes. My laptop was able to do all the numbers crunching, but with 16 gigs of RAM it took a while. I used a 16mm focal length, and the ISO was 12,800 because the church was quite dark. Noise is random, and therefore in a coposited image it disappears. Using Filter > liquify, I tried to correct some of the distortion. Click on the picture to see the entirety of it.

James R Steadman - I have done some interior drone shots in churches, taken images at various heights above the floor and then used PS to merge them into a single image. It worked well, Have not tried to do the shots like this one where you get the entire image, although I did do a shot similar to this in Sainte Chapelle in Paris, which has amazing stained glass. But that was several versions of photoshop ago and the result was not what I had hoped for - not to mention that the place was thronged with people jostling me as I tried to take the photos. These that you have done are beautiful.
