ANAMORPHIC ILLUSIONS
Creating and Printing Your Own Anamorphic Illusions
ANAMORPHIC ILLUSIONS a form of an optical illusion.
If you’re looking for something fun and creative to do and want to spend some quality time with your printer, anamorphic illusions are just the thing for you. An anamorphic illusion is an optical illusion whose effect is based on the viewing angle; in other words what seems like a perfectly normal, two-dimensional printed image becomes a stunning, three-dimensional image when viewed from one particular angle. The best part about these illusions is how simple they are to enjoy: just find them and print them, or make your own.
Anamorphic lenses are specialty tools which affect how images get projected onto the camera sensor. They were primarily created so that a wider range of aspect ratios could fit within a standard film frame, but since then, cinematographers have become accustomed to their unique look. This article discusses the key considerations with anamorphic lenses in the digital era.
OVERVIEWTwo classes of lenses are typically used in production: spherical and anamorphic. Spherical are more common and are the assumed lens type unless specified otherwise. Spherical lenses project images onto the sensor without affecting their aspect ratio. Anamorphic lenses, on the other hand, project a version of the image that is compressed along the longer dimension (usually by a factor of two). Anamorphic lenses therefore require subsequent stretching, in post-production or at the projector, in order to be properly displayed.

Anamorphic illusions became an internet sensation when YouTube user Brasspup created three different illusions and uploaded them to the popular video sharing site.
The three objects used by Brasspup were a Rubik’s cube, a roll of tape, and an ordinary shoe. When you first view the three objects in the video, they seem to be the actual, three-dimensional items depicted.
However, when Brasspup reaches down and suddenly rotates the piece of paper the items appear to be sitting on, you quickly realize that the objects are not sitting on pieces of paper: the objects are printed on the paper! Brasspup even included high-resolution scans of all three objects for you print out and try at home.

After experiencing those anamorphic illusions for yourself, maybe you will feel brave enough to try and create your own.
Lucky for you, a user named Greasetattoo over at Instructables has created a step-by-step how-to guide for creating and printing your own illusions.
You will need an image-editing program (Greasetattoo uses CorelDraw) in order to properly produce the desired perspective changes in your images, but no other software or hardware is necessary.
You will not only learn to produce and print your own anamorphic illusions, but also to draw the illusions yourself with sidewalk chalk! |
