Lately, I've experimenting with panoramas. The simplest and cheapest way is get a wide angle, not a wide-angle but a really-really wide angle, take the photo, crop and trim, and end-up with a photo that is 200 or 300 pixels tall.
I've been using a panorama head, the Panosaurus. I make between 3 to 7 photos and merge them together in Photoshop.
The multiple photos don't have much value in themselves, they are just the intermediary steps for the final photos, but I want to keep them together. The Lightroom solution is: stacking.
