Article: Optical brighteners in black-and-white photographic paper (2007)

Title: Optical brighteners in black-and-white photographic paper: appearance and degradation
Author: Sandra A. Connors-Rowe, Paul M. Whitmore, and Hannah R. Morris
Reference: Journal of the American Institute for Conservation 46, 2007, 199-213

Abstract:

Forty-five optically brightened black-and-white photographic papers from 12 manufacturers spanning 1956–2006 were studied to evaluate the brightener’s impact on appearance and its light sensitivity under simulated daylight conditions. The appearance tests showed both small and large changes in appearance when the optical brightener was activated by inclusion of UV in the illuminating light source. All papers showed a decrease in the Yellowness Index value upon brightener activation, indicating a change in appearance to a color that is whiter than its unbrightened version. Three papers that were originally warm white in appearance, however, remained somewhat yellow in color even with activation of their optical brighteners. All of the 45 papers experienced some optical brightener loss as a result of prolonged exposure to simulated daylight with UV wavelengths included; many also experienced other color changes such as bleaching or yellowing of the paper substrate and loss of a chromophore at 570 nm. All papers experienced color change rates similar to that of Blue Wool Standard 3 or 4 when exposed to light containing UV and would be considered moderately sensitive to light exposure.

Report: Treatment Practices in Photograph Conservation (2009)

Title: Current Status of Treatment Practices in Photograph Conservation

Pages: 62
Year: 2009
Type of document: Report

Abstract:

This research is an analysis of the current status of treatment practices in photograph conservation, based on fifteen video taped interviews with senior photograph conservators, conducted from January to May 2009. Te interview questions were designed to define and describe current conservation treatment practices and discuss their transformation over time. Training and future challenges of treatment are discussed briefly. The interviews and the documentation of the research process are available in http://photograph-conservation.blogspot.com.

Preservation of photographic material (2009)

Title: Preservation of photographic material
Author: Susie Clark
Publisher: The British Library
Series: Preservation guidance booklets
Pages: 19
ISBN: 978 0 7123 0909 7

From the Introduction:

Photographs are housed in libraries, archives and museums all over the world. Whilst photographic conservation is a relatively new specialism and treatment options are often limited, it is usually possible to prolong the life of a photograph through good preservation practices in handling, housekeeping and storage. This booklet describes the most common historical photographic processes,outlines the causes of deterioration and provides guidelines on good preservation practice. It is aimed at people working or volunteering in libraries, archives and museums whose responsibilities include photographic collections.Whilst the booklet focuses on monochrome photographs, much of the information is applicable to colour photographs and other imaging materials such as microfilm, x-rays and motion picture film.

Characterization and identification of printed objects (2008)

Title: Characterization and identification of printed objects
Author: Lénia Janete Oliveira Fernandes
University: New University of Lisbon
Year: 2008
Type of document: Master thesis

Abstract:

A study about the physical appearance of pre-photographic, photomechanical, photographic and digital positive reflective prints was made, relating the obtained images with the history, materials and technology used to create them. The studied samples are from the Image Permanence Institute (IPI) study collection. The digital images were obtained using a digital SLR on a copystand and a compound light microscope, with different lighting angles (0º, 45º and 90º) and magnifications from overall views on the copystand down to a 20x objective lens on the microscope. Most of these images were originally created by IPI for www.digitalsamplebook.org, a web tool for teaching print identification, and will be used on the www.graphicsatlas.org website, along with textual information on identification, technology and history information about these reproduction processes.
