This is a handheld image, no tripod, stitched together from nine (9!) separate images automatically. I selected the images in Lightroom after importing and went to "Photo Merge," then "Panorama" and I got a stitched image which I proceeded to work on like any normal photo. After the usual tweaks, I did some extra work in the form of a digital graduated neutral density filter (right half of the image with all the windows was way brighter than the kitchen area on the left). Then on to Photoshop to remove myself from a reflection in a mirror and to do a bit more dodging (brightening) until the place looked like you see above. I will post the original images soon for comparison.
Bottom line: The new Panorama feature in Adobe Lightroom is awesome and worked great in this scenario. I only had a 35mm lens with me, and I managed to stitch together an ultrawide shot from what is hardly considered a wide-angle lens.
