IMPROVEMENT OF PHOTOGRAPHIC PROPERTIES UNDER HIGH INTENSITY EXPOSURE IN HIGH CHLORIDE EMULSIONS

doi:10.7517/j.issn.1674-0475.2003.02.107

Abstract

Abstract: A series of high chloride cubic emulsions and a high chloride (100) tabular emusion were prepared and the high chloride cubic grains were doped with different dopants,iodide,(NH₄)₂IrCl₆ and K₄Fe(CN)₆,respectively.The photographic properties of these emulsions under normal exposure and high intensity exposure indicated that the photographic properties under high intensity exposure could be improved to varying contents by doping with iodide,or iridium coordination complex,or a shallow electron trapping dopant.The combination of the above methods worked more effectively.

Key words: high chloride emulsion, (100) tabular emulsion, high intensity exposure, doping
