Abstract:
An image formation method for forming a color image by imagewise exposing a color negative silver halide photographic material comprising a transparent support and at least three kinds of light-sensitive layers having thereon, followed by development processing at a temperature of 50.degree. C. or more, which comprises the steps of:reading with an image taking apparatus an image obtained from the color negative silver halide photographic material whose sensitivity and gradient satisfy the following relationship:1.0.ltoreq.(log.sub.10 S).multidot..gamma..ltoreq.2.5S.gtoreq.800;applying digital image processing thereto; andobtaining output signals of three or more colors: wherein S represents an ISO sensitivity, and .gamma. represents an average gradient of the three kinds of light-sensitive layers.
