摘要： A photographic element comprises at least one silver halide emulsion layer in which:a) the silver halide has been spectrally sensitized with a first blue sensitizing dye having a .lambda..sub.1 less than or equal to about 475 nm and a second blue sensitizing dye having a .lambda..sub.2, wherein the following relationship is met: ##EQU1## wherein .lambda..sub.1 is the wavelength in nanometers (nm) of maximum absorption of a silver halide emulsion sensitized with the first dye and .lambda..sub.2 is the wavelength of maximum absorption of a silver halide emulsion sensitized with the second dye, with the proviso that neither the first nor the second dye contains selenium. The silver halide emulsion of said layer is chemically sensitized with a gold(I) compound and preferably with the combination of a gold compound and a disulfide compound; andb) the silver halide has been chemically sensitized with a gold compound of formula (I):AuL.sub.2 +X.sup.- or AuL(L.sup.1)+X.sup.- (I)whereinL is a mesoionic compound;X is an anion; andL.sup.1 is a Lewis donor ligand.

摘要： A photographic element, is disclosed which includes a support and at least three silver halide emulsion layers, that records exposure information. The exposure information is recorded in three image-recording units and wherein the spectral sensitivities of said image-recording units are chosen such that the average color error, .DELTA.E*.sub.ab, is less than or equal to 3.1. .DELTA.E*.sub.ab is computed for a specified set of test colors of known spectral reflectance, and the light source is specified as D.sub.65. .DELTA.E*.sub.ab is the average CIE 1976 (L*a*b*) .DELTA.E*.sub.ab between the CIE 1976 (L*a*b*)-space coordinates of said test colors and the CIE 1976 (L*a*b*)-space coordinates corresponding to transformed exposure signals. The transformed exposure signals are formed by applying an exposure-space matrix to the exposure signals derived from the photographic element to transform the derived exposure signals to exposure signals corresponding to the color-matching functions of the CCIR Recommendation 709 primary set. The exposure-space matrix is derived so as to minimize ##EQU1## and noise-gain factor, .PSI., defined as the sum of the square roots of the sum of the squares of each row of the elements in the exposure space matrix is less than or equal to 6.5.
