Perspective distortion occurs when objects appear differently based on their distance from the viewer. For example, a building close to the camera may look much larger than a mountain in the background, even if the mountain is much taller. This effect can create a sense of depth and dimension in photographs and art. In photography, perspective distortion can be manipulated using different lenses. A wide-angle lens can exaggerate the size of foreground objects while compressing background elements, leading to a unique visual effect. Understanding perspective distortion helps photographers and artists create more compelling compositions.
