Volume anamorphosis correction

One of the challenges of photographing the real world is that a three-dimensional scene is reproduced in a two-dimensional image. As a result, three-dimensional objects that are not on the optical axis of the camera can appear stretched out. The steeper the angle at which rays from the subject reach the lens, the greater the apparent error — hence these phenomena are particularly noticeable with wide-angle lenses. This stretching becomes even more objectionable the nearer the objects are to the edges of the frame. Volume anamorphosis (sometimes referred to as wide-angle stretching or shape stretching) is occasionally desired as part of a photographic effect, but mostly it has been tolerated as simply inevitable.

1. Choose cylindrical correction to preserve picture components whose curvature is mainly in one direction (such as standing figures, bottles, buildings, trees or architectural columns)

2. Choose spherical correction for elements with a similar degree of curvature in all directions (such as the human head, tennis balls, apples and oranges)

3. These corrections are indispensable for wide-angle portrait, social, wedding, and architectural photography

4. Easily find your ideal balance between volume proportion and geometric accuracy
