silver halide cameras boomed, Canon launched several models covering a wide range of user needs, including the EOS-1 in Japan in 1989, aimed at professionals, and the EOS Kiss (EOS Rebel XS or EOS 500 in other regions) in Japan in 1993, which achieved a compact, lightweight design and greatly expanded Canon's user base.
The

PMA: Do you see changes within those mixes, as
silver halide may be transitioning to a sunset platform and others are growing?
For example, according to the latest version of ANSI/NAPM Standard IT9.1, polyester-based
silver halide microfilm with a residual thiosulfate content of not more than 0.014 grams per square meter of film merits a life expectancy (LE) rating of 500, meaning the film images have a life expectancy of at least 500 years when stored under prescribed environmental conditions.
The emulsion layer of your film contains many
silver halide crystals both above and below the surface of the emulsion.
Traditional
silver halide processing remains the best value in the category and will continue to increase, according to analysts.
The combination of the capabilities of
silver halide and electronic imaging are allowing growing opportunities for
silver halide imaging materials.
Kodak is unmatched in
silver halide chemistry, and layering chemicals and emulsions on paper or plastic.
For modem documentation, recopying documents onto archival-quality materials - e.g.,
silver halide microfilm or acid-neutral paper-has become an important aspect of preservation.
William Alschuler, California Institute of the Arts, USA, described how formate can increase the sensitivity of
silver halide holographic emulsions.
