Perspective distortion and optical effects are distinct concepts in photography and imaging.
-
Perspective Distortion: This refers to the way objects appear in relation to each other in an image based on the position of the camera and the subject. For example, when a camera is positioned close to a subject, that subject may appear larger compared to objects further away, leading to a distortion of proportions. Perspective distortion is influenced by the point of view and the distance from the subjects.
-
Optical Effect: This refers to any outcome produced by the behavior of light as it interacts with a lens or other optical elements. Optical effects can include things like lens flares, bokeh, color fringing, and vignetting, among others. These effects can alter the appearance of the image but do not necessarily involve the spatial relationships between objects in the scene.
Given the options you provided, the statement that best describes the difference is "It misshapes the point of view, not the lens." This indicates that perspective distortion is concerned with how objects relate to each other from a specific viewpoint, while optical effects pertain to changes caused by the lens itself.
