This was shot with an app called AutoStitch, a panorama stitching app, on iPhone 4s. You take multiple shots of a wide scene and it will stitch them automatically. It works best when you are far away from the subject. The one above was shot from a close distance of about 4 to 5 meters, hence the distortion when the app tried to stitch the multiple images. I took two rows of multiple images. The first row was for the sky and the roof of the shophouses and the other one was for the lower part of the scene. The app will automatically look for matching images and stitch them without any user input. A cool app to create a panorama image.
