Evolution of Transparent Plastic Supports, By Fernanda Valverde, 2016

Evolution of Transparent Plastic Supports

Talk by Fernanda Valverde
Plastics Associated with Photographic Materials Symposium
Tucson, Arizona. March 2016.

Abstract
This talk addresses the evolution of transparent plastic supports focusing on the periods of transition and overlapping of different materials and technologies. It highlights the challenges involved in the development and manufacture of the different types of flexible supports, and the advantages and disadvantages of each of these. The physical, mechanical, and chemical properties that were desirable in transparent supports are presented here, along with the methods introduced to achieve these properties.













Historical Review of Plastics used in Photographs, By Sylvie Pénichon, 2016

Historical Review of Plastics used in Photographs

Talk by Sylvie Pénichon
Plastics Associated with Photographic Materials Symposium
Tucson, Arizona. March 2016.

Abstract
Plastics have pervaded every aspect of our lives and photographs are no exception. Since the early days of photography, plastics have been closely associated and used in photographs as binders, substrates, coatings, and now, image materials. This presentation will briefly survey the evolution of photographic materials and plastics associated with them, from the daguerreotype era to the digital age.
