Another iPhone panorama, this time with the Pano app. I had been using AutoStitch, which makes panoramas from a series of existing photos. Pano takes a different approach: you shoot a series of photos, in order from left to right, from inside the app. After each image, the app asks if you’re happy with the shot, or if you’d like to retake it. If you’re happy with it, it stores it, and then shows you a semi-transparent slice of the right edge of the photo superimposed over the left side of the current camera viewscreen. This makes it fairly easy to line up each shot as you pan across your scene. When you’ve taken all the photos you want, the app joins the images together and saves it to the Camera Roll on the iPhone.
The upside to Pano is that it’s much easier to get well aligned images, as long as there’s enough contrast in the individual pictures to allow you to line them up as you’re shooting. The down side is that the only layout the app can handle is a single row of landscape or portrait shots. AutoStitch can join photos in any combination. The panorama at the bottom of my previous post (our back yard) was built from two rows of four photos (8 images total). The top row included a nicely exposed blue sky, and the bottom row was primarily the tussock–permafrost landscape of our backyard. Even though there are some obvious artifacts in the final image, it would be hard to get such a nice overall exposure with Pano and the iPhone camera.
