1. There are Three Stereo Slide Competition Categories:
    (1) Standard stereo; (2) Non-Conventional stereo; and (3) Digital stereo

    Standard Stereo Category is defined as all those slides made with a classic 35mm stereo camera at normal interocular. Cropping, sandwiching, multiple exposures, filtration and color manipulation are permitted as long as the original chips were made with a standard stereo camera.  Standard stereo slides will be mounted in Realist-format (1 5/8" x 4") mounts.  Here are twelve popular Standard Stereo cameras in often used by our stereo photographers in Exhibition Competitions:  (These cameras are available on ebay, so get one and enter your images in our exhibitions!)

                         Realist                    Realist 45                       Kodak                             Revere                      Wollensak                  Iloca Rapid 


TDC Vivid                    Colorist                Stereo Graphic                     Nimslo                   Belplasca                  Verascope

Non-Conventional Stereo Category is defined as all those slides made with Exakta/Kindar/Hyponars, Realist Macro Stereo, regular 35mm cameras with the aid of a slide bar, or slides with modified interocular (hyper or hypo stereo) regardless of camera used, and modern advanced cameras such as RBT stereo cameras (with their built in light meters, auto-focus, rapid wind, etc).  Non-conventional stereo slides may be mounted in either Realist-format mounts or in 2x2 standard 35mm mounts.  Popular Non-Conventional Stereo Cameras include:

        Realist Macro                    RBT S1                         RBT S4                                Twinned KR10 Ricohs           Minolta X700s on a slide bar

The Digital Stereo Category is defined as an image that has been modified in the computer. This includes images shot with film or digital cameras, that are somehow manipulated in the computer realm via Photoshop or other software, and output to slide film. This includes 2D-3D conversions.

The Competition Director shall decide the appropriate category of a slide in event of dispute.

  1. Exhibit Your Best 3 Stereo Images:  Members will be allowed to enter up to three slides in each of the three competition categories at each competition. Members should try to mount their images of one category in the same format; either Realist mount or 2x2 mount. If you must mount slides of the same category in multiple formats, please indicate this to the judging table. Digital slides are typically mounted in 2x2 mounts.

  2. Two Competition Levels exist within the standard (Realist) stereo category: an "A" (advanced) and a "B" group (all others). A member may be grouped in the "B" group in the standard category and still enter in the non-conventional or digital categories. Member's group (A or B) shall be assigned at the discretion of the Competition Director.

  3. Cumulative Scores will be computed for each member in each category. Members entering multiple categories will have separate cumulative scores for each category. These scores are not combined. The cumulative scores will be posted five times annually in the 3D Newsletter Competitions Section to track the excitement of the year’s entries.

  4. End-of-Year Awards will be given to the top scores in each group of each category. It is possible for the same member to earn the awards for different categories.

  5. How Categories are Judged: Each category shall be judged separately.  During judging, the judges may ask the projectionist to hold the slide for a comment. If made in a timely manner this is encouraged to allow the audience to learn what makes for better stereo images. A slide receiving a low score especially deserves a comment of instruction from a judge.

  6. Five Competitions AnnuallyThere will be five competitions during the year for each category.  Each category shall be judged on the same evening.  Realist-format slides will be projected with a conventional stereo projector. The 2x2 format slides will be projected by twin Ektagraphic AF-2 projectors. During the course of our five competitions photographers are encouraged to submit 3 images during each of 5 competitions for a total of 15 slides (per category they enter) over the exhibition year.  Photographers may achieve complete participation in more than one category.  The club regards complete participation as a high honor. It takes vision and courage to show your best images to a public audience.  SCSC recognizes this strong effort of the stereo photographer by awarding the prestigious Complete Participation Ribbon to each artist who achieves this level at its annual Awards Banquet every summer.

  7. Scoring Five to Nine: Judges are encouraged to measure slides uniformly by attributing the following scale of 5-9: 5) Reserved for images that hinder the audience’s 3D enjoyment; an image with a serious technical flaw, or several smaller flaws, such as stereo window violations, focus or compositional problems, no use (or little) stereo effect, mounting problems, parallax problems, and overall image effect; 6) Standard and good snapshots; images that may be personally enjoyable to the photographer and his/her friends, but not necessarily noteworthy to the general public; 7) An image that is of exhibition caliber. It breathes life by containing well executed composition, lighting, use of color, focus, or other photographic means; 8) Subject matter that is transformed by its portrayal. A definite exhibition caliber slide and a possible HM; and 9) Excellence in all respects, an image that shows the finest execution of what it portrays and deserves an HM or Award in the exhibit because it is extraordinary and memorable. While it is not easy to judge and define a level of excellence for each slide, we do encourage our judges to use the full spectrum of the 5-9 scale, as it is too easy to slip into scoring 85% of all slides a 6 or a 7.

  8. Ribbons: The top scoring slides of each group of each category shall be given Award and Honorable Mention ribbons. The number and distribution of ribbons to be awarded shall be determined by the Director.

  9. Unique Images: The same slides may not be entered in Club competition more than once during the same fiscal Club year. Slides that have won an Award or Honorable Mention in any previous Club competition in any year, or similar slides whether titled the same or different, may not be entered again.

  10. Rewarding Judges: There shall be three stereo judges for each competition. A member who is judging shall not enter slides in that competition. Judges will receive a prorated score based on their scores for all other competitions entered during the fiscal year. Judges are still encouraged (if they so desire) to submit makeup slides if they judge a competition. They can still receive complete participation by submitting 12 slides in a category and judging one of the five competitions.

  11. Mount for Projection: All slides should be mounted for projection. RBT mounts are recommended (either glass or non-glass), as are Realist format glass slides, and in the 2x2 format, Gepe Glass Slides. Cardboard mounts are the least desirable. Realist-format slides should be spotted in the lower left-hand corner as viewed in a hand viewer. 2x2 stereo slides will be spotted in the lower left-hand corner of each slide; a red spot will be placed on the left slide, a green spot will be placed on the right slide.

  12. Make-up Slides for missed competitions are allowed, as complete participation for the five competitions over the year is highly encouraged. Complete participation in one category is 15 slides submitted in competition over the September, November, January, March, and May exhibitions. Please try to keep pace and submit only 3 make-up slides at a time. Make-up slides may or may not be eligible for Awards or Honorable Mentions, at the discretion of the Competition Director.
