>>2606850Here's a little picture to help you with wide angle lenses. You most certainly have seen pictures taken with a fisheye lens before, they are a extreme version of a wide angle lens and as you know they cause a lot of distortion.

>>2606844 said, your phone has a wide angle lens as well, not as wide as a fish eye, but still wide enough to cause distortion.
Look at 35mm and 16mm in this picture, these are the results you get from a phone camera when pointed to a face or any other close object like your body. Depending on the angle of your phone, other parts of the picture get distorted, for example the lower part of your body. Exactly like photographing a building, you are right.

>>2606844Good luck with your progress bro, we're all gonna make it
