What are the techniques of anamorphic photography?

The techniques of anamorphic photography mainly include the following:
Using ultra wide angle lenses and fisheye lenses: These lenses can produce strong distortion effects, especially when shooting close to the foreground, ultra wide angle lenses can capture exaggerated perspective effects. Fish eye lenses can produce more extreme distortion effects.
Adjust shooting distance and angle:
Close up shooting: Place the camera close to the subject and keep the focus on the subject, which will cause the subject to deform and present an interesting distortion effect.
Long distance shooting: In contrast to close range shooting, keeping the camera away from the subject and keeping the focus on the subject will elongate the subject, creating a stretched and distorted effect.
Adjusting the focus position: Manually adjusting the focus position of the camera can create a special distortion effect. Try to focus on the edges or corners of the screen and observe the changes in the image.
Utilize background elements: Select background elements with perspective and symmetry, such as buildings, roads, mirrors, etc., and place the theme object in the middle or next to the background elements. By adjusting the focal length and distance, the distortion of background elements can be created, which in turn affects the presentation of the subject object.
Post processing: In post processing, lens correction filters can be used to adjust the distortion, color difference, and ghosting of photos to achieve the desired distortion effect.
