Abstract
An improved image forming method is disclosed which comprises contacting both an originating photographic element and a display photographic element with substantially similar processing solutions. The originating photographic element is characterized in that it contains at least 50 mole percent silver chloride grains and no more than 2 mole percent silver iodide, based on total silver forming the grain projected area. The grains are tabular grains bounded by {100} faces having adjacent edge ratios of less than 100 and each having an aspect ratio of at least 2.
