Tilt-shift photography is a technique that uses special camera lenses to create a unique visual effect. By tilting and shifting the lens, photographers can control the plane of focus and perspective, making real-life scenes appear miniature or toy-like. This effect is often used in landscape and urban photography to give a whimsical, dreamlike quality to the images. The tilt-shift technique can also correct perspective distortion, which is common in architectural photography. By adjusting the lens, photographers can ensure that vertical lines remain straight, making buildings and structures look more natural. This versatility makes tilt-shift photography popular among both professionals and enthusiasts.
