Abstract
Abstract Disclosed is a method for forming a silver halide color photographic image comprising: exposing a silver halide color photographic light-sensitive material for photographing which comprises a support and provided thereon at least one blue-sensitive silver halide emulsion layer (B layer), at least one green-sensitive silver halide emulsion layer (G layer) and at least one red-sensitive silver halide emulsion layer (R layer) to light to obtain a latent image; processing said latent image to obtain a color negative image; printing said color negative image on a silver halide color photographic light-sensitive material for printing which comprises a support and provided thereon a yellow color-forming layer (Y layer), a magenta color-forming layer (M layer) and a cyan color-forming layer (C layer) to obtain a color photographic image; wherein: (A) the spectral sensitivity distribution of the G layer S G (λ) has a maximum value at a certain point λ Gmax within the wavelength region 525-560 nm, and the spectral sensitivity of the G layer at 570 nm S G570 accounts for 40% or less of said maximum value; and (B) the spectral density distribution of a dye formed in the Y layer by processing said color photographic light-sensitive material for printing S Y (1) has a maximum value at a certain point 1 U 50 within the wavelength region 430-460 nm, and said maximum value is reduced to half at a certain point l Y 50 within the longer wavelength region 480-500 nm. By the method of the invention, it is possible to obtain a color photographic image in which colors, in particular, yellow and skin color, is reproduced with an extremely high degree of accuracy.
