THE EFFECTS OF FOUR DIFFERENT WET TREATMENTS ON ALBUMEN PHOTOGRAPHS
VALERIE BAAS, CHRISTOPHER FOSTER, & KAREN TRENTELMAN
ABSTRACT—The effects of different aqueous baths on the extent of surface deterioration in albumen prints were studied. Albumenized paper was sensitized, exposed, and processed. Four immersion media were used: deionized water, ammoniated deionized water (pH 9), a deionized water:ethanol mixture (1:1 v:v), and deionized water followed by ethanol. Groups of prints were treated repeatedly in each of the four baths. Drying was limited to a single method. Changes in the gloss of the albumen prints were measured at regular intervals with a glossmeter. Other changes in surface characteristics were monitored by visual and microscopic examination and phtomicrography. The effects of the different baths on the albumen layer, as well as factors such as differences in thickness and the comparative rates of wetting and drying, are discussed.
