Michigan in Pictures regularly features awesome historical postcards from Don Harrison of UpNorthMemories.com. Don emailed me the other day to let me know that the 39th National Stereoscopic Association Convention will be held in Traverse City next month (June 4-10, 2013).
The event features speakers, workshops, 3D image competitions, exhibitions and a huge 3D Trade Fair where you can view and purchase equipment and photographs. While there’s no specifically Michigan tie, I thought it was pretty cool that Brian May, CBE, PhD, FRAS is one of the featured speakers. You may know Brian as the guitarist of Queen, but he apparently postponed a career in astronomy, returning to astrophysics in 2006. He’s also a life-long stereoscopy enthusiast.
Regarding stereoscopy, Wikipedia’s explains:
Stereoscopy (also called stereoscopics or 3D imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word stereoscopy derives from the Greek “στερεός” (stereos), “firm, solid” + “σκοπέω” (skopeō), “to look”, “to see”.
Most stereoscopic methods present two offset images separately to the left and right eye of the viewer. These two-dimensional images are then combined in the brain to give the perception of 3D depth. This technique is distinguished from 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye movements.
The photo above shows the Diag at the University of Michigan. You can see it bigger along with dozens more from all across Michigan in the Bentley Library’s Michigan in 3D Stereoscopic Cards gallery.
