Consultant. Professor. Hans I Bjelkhagen, Hansholo Consulting Ltd, Glyndwr University, UK

Presentation Topic :
Early holography in sweden

Doctoral Degree in 1978 by the Royal Institute of Technology in Stockholm, Sweden. Over the last fifteen years Bjelkhagen has received much international recognition for his work in the field of colour holography and holographic recording materials. He has specialized in recording Denisyuk-type colour holograms. He has researched and improved Lippmann photography over a period of many years.

In 1983 Bjelkhagen joined CERN in Geneva, Switzerland, where he was involved in the development of bubble chamber holography. In 1984 he recorded holograms in the 15-foot bubble chamber at Fermilab in Batavia, IL, USA. Between 1985 and 1991 he was employed at Northwestern University, in Illinois, USA, working on medical applications of holography. In 1997 Bjelkhagen was invited by Professor Nick Phillips to join him at CMO at De Montfort University, Leicester, England. In 2004 CMO moved to the then newly established OpTIC in Wales.

In addition to scientific applications Bjelkhagen is a well-known holographer who has recorded many holograms for 3D display purposes. From his early years in the field, he has been involved in large-format, high-quality display holography, using both pulsed and cw lasers. He has recorded many unique art objects, such as, for example, the Swedish Coronation Crown of Erik XIV (from 1561), or the Chinese Flying Horse from Kansu (from 100 A.D.). Bjelkhagen has worked with several famous artists, for example, Carl Fredrik Reuterswärd, creating holograms exhibited in many art museums and galleries around the world. Bjelkhagen has also used pulsed holography to record many hologram portraits. The most famous person recorded by Bjelkhagen was President Ronald Reagan. His portrait was recorded on 24 May 1991. A copy of this holographic portrait is held in The National Portrait Gallery of the Smithsonian Institution in Washington DC.

Bjelkhagen has published over 100 papers in refereed journals and conference proceedings and holds 14 international patents. He has published three books: Silver-Halide Recording Materials for Holography and Their Processing by Springer and with David Brotherton-Ratcliffe as co-author: Ultra-Realistic Imaging, Advanced Techniques in Analogue and Digital Colour Holography by CRC Press, Taylor & Francis Group, 2013 and Holography and Philately – Postage Stamps with Holograms by Xlibris, 2014.

He is a member of the Optical Society of America (OSA) and a fellow of the International Society for Optical Engineering (SPIE). He is an Accredited Senior Imaging Scientist and Fellow of The Royal Photographic Society (RPS) as well as Chairman of the RPS 3D Imaging & Holography Group. In 2001 he received the RPS SAXBY AWARD for his work in holography and in 2011 the DENISYUK MEDAL, from the D.S. Rozhdestvensky Optical Society, Russia.


Dr. Yves Gentet, laser physicist, engineer, expert in holography Ultimate Holography, Bordeaux, France

Presentation Topic :
CHIMERA™ 180, a denisyuk printer

Born in 1965, he built his first holographic laboratory when he was still a student in his engineering schools. He then worked on the holographic Head Up display system of the french military aircraft “Rafale” and other holographic military product . He developed for these applications an optical software including holographic elements . From 1992, he built his own laboratory and started a new manufacturing process of color holograms, adjusting a very fine grains emulsion “Ultimate”, which combines a very high sensitivity and resolution. With this material, numberous color holograms have then been manufactured, many exhibitions worldwide done, and several complex systems using this material developed.

The Ultimate material is actualy used by about 200 users worldwide (schools, universities, artists, hobbyists, companies…) for display, interferometry, Hoe’s, mastering for photopolymer applications.

Profile : Display holography and its applications including – color holography, pulse holography – holographic recording media and processing – manufacturer of systems and instruments for holography: mobile color camera, holoprinters, mobile studio portraiture system

Publications, reports, awards : Several articles in scientific journals. More than 10 reports on national and international scientific conferences, patents. 2 IHMA awards, Denisyuk Medal (2015) and other awards for inovation.

Architect. Photographer. Filipe da Veiga Ventura Alves, Portugal

Presentation Topic :
Rediscovering beauty: A photographic journey through the albumen Lippmann process

Filipe da Veiga Ventura Alves is an architect, photographer, and visual effects artist based in Lisbon, Portugal. With a passion for exploring the limits of scientific and artistic expression, Alves has spent years pushing the boundaries of his fields and discovering new techniques and processes.

Alves spent 15 years working in special effects and 3D animation for television and cinema. During this time, he also developed a passion for astronomy and astrophotography as a hobby, spending a decade exploring the cosmos and discovering several planetary nebulae.

In 2010, Alves co-founded 1825 Studio, a laboratory for the construction of architectural images that seek to develop new representation methods. At 1825 Studio, Alves leads a team of artists and architects in creating images that balance scientific precision with dreamlike atmospheres, conveying the character of a particular environment in a way that seduces and lingers in the viewer's memory. In addition to traditional techniques, the studio also employs cutting-edge virtual reality technology to enhance the visual experience.

Building on his passion for image-making, Alves established Silverbox in 2012, a photography studio specializing in wet plate collodion photography and other historical photographic processes. At Silverbox, Alves creates portraits in large format, blending classic techniques with modern aesthetics to produce singular and expressive images.

Alves is one of the few people in the world who practices Lippmann photography, a long-forgotten photographic process that he has helped rediscover. He has participated in exhibitions at the Preus Museum in Norway and the Photo Elysee Museum in Lausanne, showcasing his expertise in albumen Lippmann photography.

Alves' work is characterized by his commitment to exploring the limits of his fields, his attention to detail, and his dedication to capturing the essence of his subjects. Whether he is creating architectural images, producing stunning photographic portraits, or rediscovering and practicing forgotten photographic processes, Alves' work is driven by his passion for discovering new ways of seeing and understanding the world around him.
