About Luis Nadeau

Luis Nadeau became involved in the archival aspects of photography in the early 1970s.[i] Coming from a background in conventional photography, he took a course in the then new field of conservation and restoration of photographic materials, offered by the Visual Studies Workshops in collaboration with the George Eastman House, in Rochester, New York, U.S.A.

Rochester was a turning point for Nadeau, who quickly realized that the fields of conservation and restoration of photographic materials were in their infancy. The formal academic programs were not sufficient and only those comfortable with foreign languages and an autodidactic approach could eventually contribute to the advancement of this new discipline. This suited him perfectly. Born with an insatiable curiosity and unquenchable thirst for knowledge, he used to read over four hundred books a year, year after year.

During the 1970s he repeatedly went to Europe, researching in patent offices, museums, national libraries and the still mostly intact Alphonse Poitevin research laboratory, rue Saint-Jacques, in Paris. From 1976 to 1979 he was also the official Canadian delegate of NAPA (National Association for Photographic Art –now CAPA)[ii] at the Rencontres Internationales de la Photographie (RIP)[iii] in Arles in the south of France, and was a regular contributor to its quarterly, Camera Canada, then edited by well-known Canadian photographer, Freeman Patterson.

The press privileges included access to all conferences, workshops and social events in Arles. He became personally acquainted with Ansel Adams, Manuel Alvarez Bravo, Paul Caponigro, Lucien Clergue, Ernst Haas, Helmut Gernsheim, Ralph Gibson, Jean-Claude Lemagny, and many other prominent historians and photographers.

Beginning in the late 1970s and 1980s he was teaching workshops on early photographic processes at the Maine Photographic Workshops, in Rockport, Maine and elsewhere in North America.[iv]

While researching the history of photographic technologies, he turned his attention to the so-called “permanent” or “archival” processes. Such printing processes do not make use of silver or dyes that would tarnish or fade. This research unveiled the Holy Grail of photographic printing: the Fresson process. The procedure, worked out in France at the end of the nineteenth century, belongs to the dichromated colloid group, originally discovered by Alphonse Poitevin in 1855. A mixture of a colloid, pigment and dichromate compound creates a light-sensitive emulsion. After exposure under a negative the non-exposed parts of the emulsion are relatively soluble and can be removed with a slight abrasive. This is usually done by pouring a mixture of sawdust and water over the pigmented (dark) print until the desired density is achieved.[v] See the Fresson entry in the photographic gallery of the Museum.

The process provides extensive control, as development occurs slowly in bright light and the finished prints have a unique matt look that was very popular among pictorialists. In 1951 the process was adapted to four-color printing and to this day remains the only method of producing real photographs[vi] in permanent colors on a commercial basis.[vii]

In recent times, artists such as Frank Horvat, Bernard Plossu, Sheila Metzner, and Sarah Moon have had their work finished in Fresson. The best known exponent of the process, however, was the late José Ortiz Echagüe (1886-1980) whose fabulus work can be seen in major museums, including that of the Royal Photographic Society in the U.K. and the Metropolitan Museum of Art in New York.[viii][ix] In 1966, Ortiz Echagüe, who was a wealthy Spanish industrialist, managed to purchase the secret Fresson formulas and coating equipment from a rogue Fresson family member who was giving up the commercial production of paper for health reasons. After years of difficult and sometimes tumultuous negotiations in France and Spain, Nadeau stunned the photography world [x] in 1979 by bringing the Fresson formulas and equipment to Canada.

Nadeau’s research has appeared in hundreds of books, journals, and web sites. [xi][xii] He has also done consulting, lectured and trained the staff of well known institutions from 13 countries. These include the Canadian Centre for Architecture in Montréal, the MET in New York City, the Bibliothèque Nationale, the Musée du Louvre and the Maison Européenne de la Photographie in Paris (where he hosted the first international meeting on photo-alternative processes, in May 1996), the Biblioteca Nacional in Madrid, the Benaki Museum in Greece, the International Center of Photography in New York City, the Museum of Science at Oxford, the Oxford English Dictionary, the Smithsonian Institution, Harvard University, the Getty Research Institute, the University of Texas, etc.

Shortly after September 11, 2001, he cancelled a lecture that was to take place at the annual meeting of the American Institute of Conservation, in New York City. Missing such an opportunity, he then created what has become the very successful PHOTOCONSERVATION mailing list:  The who’s who of the conservation world subscribe to this list, now with more than 950 participants.

[v] The processing (not the coating procedure and formulas) of Fresson paper is detailed in Luis Nadeau’s History and Practice of Carbon Processes, 1982, pp. 53-62.

[vi] Real photographs as opposed to photomechanical reproductions like offset or inkjet (aquagravure, giclée, etc.) printing.

[vii] Nadeau never used the color version of the Fresson process. The descendants of the inventor are still using it in France.



[x] Christina Sabat, a journalist who interviewed Nadeau on the acquisition of the Fresson process wrote: “It is a dramatic tale which has all the ingredients for a successful mystery thriller including drama, intrigue, suspense and the involvement of prominent and wealthy personages.” The Daily Gleaner, Fredericton, NB (May 24, 1980), p. 5. Indeed, by the time the transaction was finalized, it had directly involved a large number of people in four countries.
