This is the greenside area of the third hole at Tianna Country Club in Walker, Minnesota. The ripples from my failed approach shot have faded away. What interests me is the birch trees and their reflection in the pond. In real life they were perfectly upright.
I photographed the scene with my iPhone SE, which has a fairly wide-angle built-in lens (29mm I think), but I don't remember encountering this much distortion using wide-angle lenses on my old film and digital cameras.
I've encountered obvious distortion with this phone taking panorama images, but this was a conventional one. I need some education on the "why" and any coping techniques, and I figure asking the readership here will be faster than searching the 'net. Thanks in advance.
