The San Francisco / Bay Area's Club for Stereo Photography Enthusiasts



2025 Special Stereo Challenge

Each year the Golden Gate Stereoscopic Society selects subjects for our Special Division slideshows. Anything goes at our Open Division slideshows, while our Specials give the challenge of shooting within the confines of a specific subject or technique.

January 2025Double OpenOur traditional month of two Open Division slideshows
February 2025Through the window (Negative Parallax)Parallax defines where objects appear in 3-D space, with positive parallax placing objects “behind” the screen. Compose a stereo photo that utilizes negative parallax to reach out and grab you
March 2025RivalryEach eye is presented with a different image in stereo photography, and discrepancies between the two photos in a stereo pair cause the visual disturbance “retinal rivalry.” Take advantage of intentionally out-of-sync elements in a stereo photo creatively
April 2025Mergers (aka Interference)Exploit stereo photography’s ability to separate objects in z-space. For example, imagine a photo of a thicket of trees; only in stereo will that photo reveal each individual tree rather than a mess of branches
May 2025HyperstereoExaggerate depth with a wide distance between cameras or exposures. Find a suitably distant subject to keep the parallax comfortable to view
June 2025HypostereoA short stereo base less than the average interocular distance (the distance between eyes is about 65mm) is defined as hypostereo. Use a narrow base to photograph subjects up-close, or incorporate a macro lens for stereo macro photography
July 2025PseudoA unique ability of a stereo pair is to show the subject “inside out” by swapping the left and right images when viewed. Explore intentional pseudostereo images for a creative effect
August 2025False FramesCreate a mask or frame that compliments a stereo photo, and set it in space creatively
September 2025ColorHighlight realistic color, or manipulate colors in a stereo photo creatively. “Color” covers a lack of color as well, including monochromatic and black & white stereo photos
October 2025CreativeThe Photographic Society of America’s definition of creative is “altered reality.” Anything goes!
November 2025ActionCapture motion in stereo with your stereo camera or synchronized camera pair
December 2025ScapesLandscapes, seascapes, cityscapes – “scapes” are among the most popular subjects in international stereo exhibitions
