Double Vision: Presentation Peers into Depths
"The brain loves to be convinced," says College of the Canyons math professor George Rhys of his experiments in viewing the third dimension from 2D photos via stereoscopy. "Just how depth perception is accomplished by the brain is something worth pondering."
Rhys explores the science of stereoscopy - a technique invented in 1838 to view three dimensions from photographs - with equipment of his own creation and presents examples of his work along with a discussion of the brain's inner workings during his scholarly presentation entitled Double Vision: Depth Perception and the Brain, taking place in the Performing Arts Center on April 4 at 4 p.m.
Rhys began dabbling in the field of stereoscopy more than a decade ago, creating the ability to add depth to landscapes and developing portraits of his children that spring to life.
"The technique of stereoscopy is as old as photography itself, but has many modern uses," said Rhys, "from the ViewMaster to NASA's photographs of Mars."
His hobby turned into a fascination with the subject, and led to researching the theories behind depth perception and the way the brain processes depth.
"My best guess is that the depth effect is based on the brain's inability to make a single image out of binocular input," said Rhys.
Attendees will be able to view many of Rhys' photographs and will learn how to create their own stereoscopic device.
"Its surprisingly simple," said Rhys.
The event is free of charge and open to the public, but attendees are asked to rsvp in advance to the College of the Canyons Foundation at: (661) 362-3493.
