Tilt-shift is a photography technique that uses special lenses to create a selective focus effect, making real-life scenes appear miniature. By tilting the lens, photographers can control the plane of focus, while shifting allows for perspective adjustments. This results in images where only a small part is sharp, while the rest is blurred, mimicking the look of a small model. This technique is often used in urban photography, where it can transform cityscapes into toy-like scenes. Tilt-shift can also be applied in video production, enhancing the visual storytelling by creating a whimsical or dreamlike atmosphere in films and commercials.
