Lesson plan

Anamorphic format

Anamorphic format is a cinematography technique that captures widescreen images using recording media with narrower native aspect ratios. Originally developed for 35 mm film to create widescreen presentations without sacrificing image area, the technique has since been adapted to various film gauges, digital sensors, and video formats. Rather than cropping or matting the image and discarding visual information, anamorphic capture employs cylindrical lenses to horizontally compress or "squeeze" the image during recording. A complementary lens is then used during projection to expand the image back to its intended widescreen proportions. By using the full height of the film frame or sensor, this method retains more image resolution than cropped non-anamorphic widescreen formats, and has an inherently wider horizontal field of view. Anamorphic lenses have more complex optics than standard spherical lenses which require more light, and can introduce distinctive distortions such as lens flares and oval shaped bokeh. However, these artifacts are sometimes deliberately embraced for their aesthetic appeal.…
