Thanks to our 550m² (2nd floor) + 330m² (3rd floor), we can host numerous exhibitions and demonstrations on 1.8mx0.8m tables.
The 3rd floor is generally closed to the public during the week and is available from Wednesday to Friday for small activities between ISU members, if needed. This ensures secure storage without the need for constant supervision.
Those wishing to set up a small exhibition open to the public throughout the week are welcome. They can do so on the 2nd floor, but must arrange for supervision of their stand from at least 10:00 AM to 5:00 PM each day. Our volunteers cannot guarantee the security of your items, nor provide explanations to the public. At that time, approximately twenty tables (shown in light yellow on the 3rd floor plan) are potentially available. Please wait September 2026 and contact us at isu27exhibitions@csmn.ch to submit your exhibition proposal.
As part of the trade fair, you can also reserve a table on the 3rd floor and have a stand accessible to the public only during the weekend. At that time, approximately ten tables (shown in light blue on the 2nd floor plan) are potentially available. Please wait September 2026 and contact us at isu27tradefair@csmn.ch to reserve your table.
Throughout the congress, the local CSMN club will provide 10 passive LG OLED 3D TVs in the exhibition area. A selection of slideshows and images can then be presented to the public during the day, perhaps encouraging them to return for the evening sessions at the Plaza cinema.
The ISU will be featured, presenting its 50th anniversary photobook through three slideshows from ISU Code 33. The SSS/SGS will showcase the winners of its last 20 annual competitions. CSMN will also offer a selection of images and slideshows to highlight a more local aspect of the event.
Other clubs can submit their images in MP0 format, from 2x1920x1080 to 2x3840x2160, numbered in order of presentation, which will be shown on a loop with no sound. Alternatively, they can submit a slideshow from a competition or other event, in a 1920×1080top-bottom half-height format.
To ensure the smooth running of the exhibitions (without excessive noise), the TVs will be equipped with 3-4 headphones if necessary.
Each club will have the opportunity to describe its offerings in a few lines on an A4 page. Please note that initially, we cannot accept individual proposals, but only proposals submitted on behalf of an ISU stereo club. Ideally, each club should propose a show of no more than 30 minutes, preferably from a few years ago. Contact us at isu27exhibitions@csmn.ch to submit your exhibition TV3D show and we will send you instructions for downloading,
3DTV Shows registration opens September 26. Closes 31 January 2027.
Recent shows must be offered for the evening or week-end sessions at Cinema Plaza. See Shows page for that.
Throughout the congress, for example before and after an excursion or a 3D screening, our volunteers will be waiting for you each day from 9:00 to 23:00 at the spacious ISU refreshment bar in the People’s House, where you can have a drink and chat, or enjoy the exhibitions.
With about thirty seats at the bar and around twenty around a few tables, nearly fifty people can sit and enjoy a local beer or coffee roasted at 1000 meters altitude, all at very reasonable prices.
This ISU congress will offer on the 550 m2 2nd floor numerous exhibitions open all week to the external public of ldcf27.
The local Neuchâtel Mountains Stereoscopic Club (CSMN) will present large parts of its last 10 years of 3D exhibitions:
Lycée Blaise-Cendrars of La Chaux-de-Fonds (CH) 2022 & Gaillac (FR) 2023 : Macro-Micro-Myxos, les myxomycètes ne manquent pas derelief /(slime moulds)
In collaboration with Bernard Jenni (microbiologist, author of the original images with focus-stacking technique), the fascinating world of these polymorphic organisms, which are neither plants, nor animals, nor fungi, is presented in giant 120×80 cm anaglyphs with magnifications of nearly 1:100… with one giant wheatstone as a bonus. In addition, real specimens can be observed under 40x digital magnifiers.
Lycée Blaise-Cendrars of La Chaux-de-Fonds (CH) 2024 & Whir-au-Val (FR) 2025 : Les micro minéraux ne manquent pas de profondeur (micro minerals)
In collaboration with Michel Fels (an amateur micromineralist from Alsace and author of the original images with focus-stacking technique), this time the small-scale mineral world is presented in giant anaglyphs measuring 120×80 cm, with magnifications of nearly 1:100… and of course, one giant wheatstone specimen as a bonus. In addition, samples can also be viewed under 40x digital magnifiers.
The goal of this full week-end demo/workshop is to offer a fully immersive and interactive experience in the world of 3D, and to raise public awareness of long-exposure techniques, particularly those known as light painting.
This workshop involves the public participating either passively (as spectators) or actively (as both actor and spectator) in the live construction of a 3D image using light tools, notably those created by Jadikan and Olivier Faÿ. Both artists will showcase their talent for light improvisation. Daniel Chailloux participated in the development of the live 3D projection system and is managing it.
The setup uses two Olympus OM10 digital cameras connected via HDMI cables to two projectors. The Olympus cameras feature a Livecomposite shooting mode, which offers the advantage of almost instantaneous visualization (within 0.5 seconds!) of the image being created.
The two images will be stitched together live on a computer and projected side-by-side in anamorphic format onto a 3D TV or 3D projector, allowing users to experience 3D in real time. The shooting and projection will, of course, take place in the same darkened space, on the 2nd floor scene.
We can already announce that we will provide many display stands for 3.5×7″ (89x178mm) Holmes cardboards created by ISU members.
Each wooden mount can display 24 simple or double-sided cards. With double cards, two identical cards could be used, one for viewing the stereo pair horizontaly and the other for viewing the back image/description verticaly. If the vertical mount is not used for verso, you can show special explanation about yours cards.
We already have four mounts of 24 cards (4 sets of 6 cards or 6 sets of 4 cards), so potentially 16 to 24 people can participate in this presentation throughout the congress. Two OWL 3D-based viewers (OLW3D Lite in fixfocus wood mount and OWL3D standard adjustable) will allow for optimal viewing under LED lighting in daylight color temperature.
You will have the opportunity to put into practice the advice given by Steve Hughes during his ISU 25 workshop in Wageningen… get your cardboards ready!
The trade fair will take place saturday and sunday from 9:00 to 17:00, on 330 m2 on the 3rd floor of the Maison du Peuple.
If you would like to reserve a space/table, please send a request to isu27tradefair@csmn.ch.
You can already start thinking about what you to present/sell durng the fair, but please wait until the end of September 2026 to submit a formal and, if possible, detailed request .We will then contact you with pricing information and available spaces.
Trade fair space: 330 m² available, 15 shared spaces and approximately 30 tables of 180×80 cm.
Under the Cartoscope label, Nicolas Menet develops his original vision of stereoscopy by combining the most modern 3D tools with historical images, offering 3D VR tours as well as low-tech viewers and printed images.
Julien Damoy old stereocards in modern version with increased 3D depth, encapsuled in a 3D VR world.
The immersive StereoRama installation with the presentation of previously unseen and authentic 3D images from 1904 of Commander Charcot’s first polar expedition to the Antarctic continent, in a modern colorized version of the original glasse plates.
Hugo Clément, a stereoscopic underground photography enthusiast, awaits you in his tent—or perhaps more accurately, his cavern—to present a collection of stereoscopic underground photographs taken using vintage viewers adapted for the digital age.
These are abandoned quarries, the Parisian catacombs, but also, from time to time, a sewer, a utility tunnel, or even a natural cave.
Most of the time, he invites you to follow him into the underground spaces of the Paris region. However, he sometimes ventures far beyond the périphérique (Paris ring road)!
Christian Gimel: Lenticular portraits
A photographer by training, Christian has dedicated himself passionately to lenticular portraiture for several decades. After initially teaching himself, he met Henri Clément, a true professional in lenticular imaging. Their discussions confirmed the quality of his 3D photographs and the effectiveness of his technique. Since then, he has continuously refined his shooting systems to capture the few seconds of stillness required for his portraits.
His constant concern: to make 3D stereoscopic portraits as affordable as possible. It remains a luxury, but every day he improves his technique to reduce the cumbersome computer correction processes involved in developing and printing images. Unfortunately, the cost of lenticular film and the assembly of the overlapping photo grid is an unavoidable factor.
While waiting for you to commission a portrait from him, he will be exhibiting and presenting his work during the fair.
