Our latest method of selecting the top stereo photos in our meetings’ slideshows, ranking each photo on a scale of 1 (“OK”) to 5 (“Wow!”) during the slideshow, has improved participation and engagement. But the ranking is somewhat arbitrary, as everyone has their own definitions of “good” or “bad” stereo. 

With this in mind I updated our judging guidelines, now posted on ggstereo.org:

These guidelines are based on a scoring system originally proposed by the Stereo Society of America (an offshoot of the Photographic Society of America) in 1951. They were followed by the stereo division of the Oakland Camera Club (now the Golden Gate Stereoscopic Society) for decades. In the early 2000s we updated our evaluation guidelines for modern stereo photography technologies and techniques.  I’ve made even more adjustments to fit our style. Please review them at your convenience and let me know if you have any suggestions.
