Panoramic Mergers. I stumbled across the technique a decade ago when I was wishing for a wider angle lens for my medium format film camera.
On an amazingly calm Patagonian morning last month this scene could have been easily captured with a single frame with my Nikon D810, but by instead making a panoramic-merger from 8 images I created this highly-enlargeable, 80-megapixel image. Have I mentioned that I love this stuff?
