Distortion

Photoshop does photomerge. It will combine photos to produce a panorama. It’s a bit more complicated than iPhone. Apparently if you shoot a series vertically and try to merge them, you get a good amount of distortion. Sometimes that’s a good thing. It’s not realistic, but it is a function of the method. Okay!

Wide angle distortion. It’s what comes from holding the camera in one place and rotating. One could pan as you walk but then it would be work.
