The iPhone has had a major impact on personal photography. While it’s nowhere near as capable as my Fuji X-T1, it is both an exceptionally capable and flexible photographic implement, and the camera you always have with you. One of the very cool built-in features is the panorama function. On my way home from work today I was having fun playing with it, and testing out the low-light quality simultaneously.
As you can see, you achieve a panoramic image by swinging the camera from left to right (or in some cases top to bottom- This can also be reversed and swung the other way). You can do an up to 360-degree image. Because of the rotation of the camera, you get linear distortion.
When used carefully, This can make for some interesting images. The curves really highlight the shapes and the light in the scene. Used poorly, it can drag your eye (and hold it) in an ugly and/or uninteresting part of the image.
Another effect is if you have subjects moving through the scene, they can get stretched or compressed, depending on their speed of motion and direction, relative to the camera’s rotation. You can see that very clearly in this image.
Nighttime exposures present some challenges to image quality, especially when combined with the swinging of the camera to stitch together the exposure.
As a last comparison, here’s a daytime panoramic:
