Radiographic elements exhibiting increased covering power and colder image tones

A radiographic element comprised of

• a transparent film support having first and second major surfaces and, coated on each of the major surfaces of the support,
• at least one layer containing
• a tabular grain emulsion including a gelatino-vehicle and silver halide grains having a mean equivalent circular diameter of greater than 0.3 micrometer and containing greater than 50 mole percent bromide and less than 3 mole percent iodide, based on silver,
• a covering power enhancing compound containing at least one divalent sulfur atom adsorbed to surfaces of the silver halide grains, and
• a water soluble polymer chosen from the class consisting of polyacrylamide and dextran, in a weight ratio of the polymer to the gelatino-vehicle of at least 0.1:1.
