STEREO SLIDE COLLECTING

STUDIO 3D COLLECTS stereo images of every sort, but the main collection consists of
vintage (1950-1970's) stereo transparencies. These slides must be graded and categorized.
Both of these tasks are subjective, but we will here describe our system.

GRADING / CATEGORIES / SLIDE FAQs / LABELS

GRADING COLORS and VALUES

3/4" ROUND stickers are wrapped around the top center of a stereo slide, showing grade. Grades are not permanent and can be up or downgraded at any time... there's often a "what was I thinking?" upon review! Or tastes are refined with a more mature collection... it's all subjective, anyway.

STEREO SLIDE CATEGORIES

Categories are tough to develop, since images may often fall into multiple categories.
We try to determine the strongest element in the image for category placement.
Categories may also be determined by one's own collecting interests. Our current category list:

SLIDE FAQs

WHICH MOUNT IS BEST FOR STEREO SLIDES?
We have decided, after many years and millions (?!) of slides, that RBT plastic mounts are by far the best and most versatile. Near any slide pair can be accommodated, from Nimslo to full-frame.

IS IT BEST TO KEEP THE ORIGINAL MOUNT?
We do like to keep the original mount if the stereo window is well placed and images are aligned. However, many images benefit from precision mounting so many do get remounted. We do not like to store glass slides, so glass almost always is removed. (Glass adds weight and thickness, as well as inability to clean properly for scanning or viewing.) B quality slides are usually remounted in heat-sealed cardboard, while A quality are remounted in RBT.

HOW ARE DESCRIPTIONS TRANSCRIBED TO REMOUNTED SLIDES?
Descriptions add much to the value of an image so we like to keep any information from the original mount. If on a label, the label may come easily off (especially if under glass), and can be adhered to new mount with double sided tape. But if there is writing on the (card) mount or on a label glued to glass, we use a piece of clear packing tape to rip off the top layer of paper with the enscription hopefully still intact. Worse can scenario is that the words and date are simply transcribed to the new mount. (It's best, if possible, to get the original writing for personality and to match against other slides to see if same photographer shot them).

DO YOU OFTEN KNOW WHO DID THE PHOTOGRAPHY?
Unfortunately in most cases the photographers are unknown. If we are lucky enough to know who took the photos, we make sure the names are on the mounts- often we print author's name on labels when there are many by same person. Knowing the photographer also adds value to an image.

DO YOU TRY TO KEEP "GROUPS" TOGETHER?
Yes, and no. Very often one will get a series of images of the same situation or people. While we try to keep groups together, very often they are split due to grading differences or simply filing glitches. Also, when we run across very similar images, we will pick one to keep and put the other one up for sale or trade.

HOW ARE STEREO SLIDES STORED?
Good question! We were in favor of slide pages in notebooks for many years- especially when our slide shows were mostly 2x2 slide pairs. Now that we have shifted to 41x101mm single mounts for slide pairs, we have also shifted to drawers with boxes of slides. They just seem more easily transported and accessed. Pages or boxes? There's good reasons for either. We still use both.
