Explain in detail how to shoot panoramic shots like a photographer.

This is the effect of short focal length shooting, that is, a small wide-angle lens commonly known as fisheye lens. Wide-angle lens has a wide viewing angle, a wide shooting range, a more obvious perspective relationship between far and near, and a large image deformation, that is, barrel deformation. This photo was taken from a super wide angle, resulting in image distortion. Wide-angle lens is often used to take panoramic photos, but ultra-wide-angle fisheye lens is rarely used to take panoramic photos because of its great deformation. Only when it is used to take pictures can this deformation effect be shown. There is no clear definition, which can be regarded as a kind of panoramic shooting.
