Selenium toner on Kodak Bromesko paper
Silver Gelatine Paper (exp 1976) and drydown effect experiment
Image taken on Rolleiflex using Ilford XP2 film developed in DD-X on Kodak Bromesko paper (exp. 1976) and selenium toned.
Silver Prints on Kodak Bromesko Silver Gelatine Paper (exp 1976)
The original prints were produced on Kodak Bromesko paper, grade 2, with an expiration date of 1976. This paper likely possesses a higher silver halide content compared to modern papers. While designed for compatibility with various darkroom processing chemistries, complete archival and final results necessitates steps beyond simple fixation.
Selenium Toning for Enhanced Contrast
Selenium toning converts metallic silver in the image to silver selenide, increasing contrast in the final prints.
Experimental Procedure and Observation:
I used Kodak Rapid Selenium Toner (exp. 2011) diluted 1:7 (150 ml toner to 1000 ml H20) was used at a temperature of 35ยบ Following toning, the prints were subjected to a drying process. The prints are currently undergoing a period of observation for several days to assess any further changes in their physical properties. A detailed record of the selenium toning process is being maintained.
Safety Considerations:
It is important to emphasise the hazards associated with selenium toning. The process uses potentially toxic materials, especially at elevated temperatures, which is ironically when the chemical reaction is most efficient. To mitigate these risks, the use of a respirator or face mask during the toning procedure is a good idea. Additionally, ensuring adequate ventilation within the workspace is crucial to prevent inhalation of the fumes created by this particular photochemistry process.
Future Analysis:
The final results of this experiment will be evaluated upon completion of the observation period. This evaluation will focus on the effectiveness of the selenium toning process and how it progresses during the oxidisation process in order to achieve the desired increase in contrast, from a grade 2 silver print on the expired Kodak Bromesko paper using expired chemicals.
