The role of tilted lens

Change the depth of field, correct perspective, and create perspective.

1. Change the depth of field: Tilt the lens so that the imaging plane of the camera and the object plane are no longer parallel, but present a certain tilt angle. In this way, the light rays formed by the camera lens will show different focus points on the imaging plane, resulting in differences in depth of field and focus. A tilted shot can make certain objects or parts of a scene appear sharper, while other parts appear blurry, thereby highlighting the importance of the subject element.

2. Perspective correction: A tilted lens can correct the perspective distortion of buildings or other vertical objects in photos, making these objects appear more three-dimensional and natural in photos without appearing tilted. or deformation.

3. Create perspective: tilting the lens can create special perspective and picture effects, such as overhead view, bird's eye view, close-up view, etc., thus presenting a unique photography effect.
