Abstract

Abstract The present invention provides a silver halide color photographic light-sensitive material which has a high sensitivity and a high image quality, and a method and apparatus for forming an image by use of the light-sensitive material. The light-sensitive material comprises a support having provided thereon three light-sensitive units each having a different color-sensitivity, wherein one of the light-sensitive units is a white-sensitive unit having a spectral sensitivity distribution satisfying the following conditions. The method and apparatus for forming images using the material, in which the material is imagewise-exposed and subject to processing, thereby forming an image, the image is read out by an image pick-up means, then subjected to digital image processing, and three or more color output signals are obtained. 0.05≦S 450 /S 550 ≦1.2 and 0.05≦S 600 /S 550 ≦1.2 wherein S 450 , S 550 and S 600 represent sensitivities at 450 nm, 550 nm and 600 nm, respectively.
