The pictures on the still left illustrate bowing of the vertical lines. This occurs when capturing at a wide angle, which is usually needed to show much more of the area.
The photographs on the appropriate have been corrected to straighten the bowed vertical strains.
Visuals shot with fisheye lenses are much too distorted and are unable to be approved.
Brief Tip:
If taking pictures with a zoom lens, check out not to shoot at the widest setting. This can improve bowing.
