The Canadian Centre for Architecture is pleased to present a day-long
workshop on

IDENTIFYING, UNDERSTANDING AND PRESERVING PRINTS, PHOTOGRAPHS, AND
PHOTOMECHANICAL REPRODUCTIONS - A Workshop for Curators, Conservators,
and
Historians

Instructor: Luis Nadeau
Guest Speaker: Judith Reed

Sunday, October 5, 1997 (10 AM to 6 PM)
The Canadian Centre for Architecture
Montreal, Quebec, Canada.


Luis Nadeau (Atelier Luis Nadeau, Fredericton, New Brunswick, Canada)
will
lead a comprehensive workshop on "The Technical Assessment of Prints and
Photographs (Documentation, Use and Analysis of Physical Evidence)". 
Mr.
Nadeau, an independent scholar and history of technology specialist, is
the
author of the ENCYCLOPEDIA OF PRINTING, PHOTOGRAPHIC, AND
PHOTOMECHANICAL
PROCESSES, (1989, Atelier Luis Nadeau) and has written a series of books
detailing the history and practice of historic photographic processes. 
Mr.
Nadeau will emphasize gathering and understanding the physical evidence.
He
will provide tips on determining the technical provenance or date of an
image
based on characteristics such as the process used, paper dimensions,
type of
paper, watermark, and type of ink.  During his workshop, participants
will
have the opportunity to examine samples of many types of prints,
photographs
and photomechanical reproductions, including:  albertypes; aquatints;
4-colour carbons; collotypes; daguerreotypes; Goupil gravures;
Leggotypes;
mezzotints; Mosstypes; photoengravings; photopolymergravures;
platinotypes;
silver gelatin prints; woodburytypes; and wood engravings.  Together we
will
consider HOW, WHEN AND WHERE these prints were made.  In lectures, slide
presentations and hands-on study sessions we will learn how this
knowledge
can enhance the scholarly value of prints and help to determine
appropriate
approaches towards their handling, exhibition and conservation.


Judith Reed (Conservation Librarian, New York Botanical Garden Library)
will
join us to present a slide lecture and practical session on The
Identification and Care of Architectural Photo-reproductions.  Ms.
Reed's
talk will be based on her experience with the New York Botanical Garden
Library's large collection of architectural plans, which includes many
architectural duplicates produced by a great variety of
photo-reproductive
processes.  She is a co-author of "Photo-Reproductive Processes Used for
the
Duplication of Architectural and Engineering Drawings: Creating
Guidelines
for Identification", by Judith Reed, Eléonore Kissel, and Erin Vigneau,
an
article which appeared in the BOOK AND PAPER GROUP ANNUAL (Vol. 14,
1995,
The Book and Paper Group of the American Institute of Conservation of
Historic and Artistic Works).  Her presentation will focus on the
history of
these duplicates, their intrinsic problems, nomenclature, conservation
issues, storage, handling, and current recommendations for copying
originals
and duplicates.  During the practical session participants will look at
examples of aniline prints, blueprints, Pellet prints, diazotype prints,
sepia diazotype prints, electrostatic prints, ferro-gallic prints, gel
lithograph prints, photostats, Van Dyke prints and hectographs.


The Canadian Centre for Architecture is a study centre and museum
devoted to
the art of architecture and its history.  The workshop will include a
tour
of the collections storage facilities and conservation laboratory of the
CCA.

The workshop will be presented in English.   Mr. Nadeau is fluent in
French
and English and will welcome questions in either language.
