When photographing subjects with a wide-angle lens, it’s pretty common for perspective problems to present themselves in the form of lines that should be straight, but appear curved and distorted. This is commonly referred to as barrel distortion, which occurs mostly in wide-angle lenses because the magnification of the image decreases the farther the subject is from the optical axis of the lens. In plain speech, it means that when looking through a wide-angle lens, anything that is at the edge of the frame will be prone to appearing curved.
