Abstract
A method for forming a color image of a color negative photographic material which comprises subjecting a color negative photographic material to a color development processing, said color negative photographic material comprising a support having provided thereon at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one blue-sensitive silver halide emulsion layer, having a specific photographic sensitivity of 100 or more and having each of the gradients .gamma..sub.AR, .gamma..sub.AG and .gamma..sub.AB of 0.5 to 0.9 after standard color development processing within the range of from 3 minutes to 4 minutes of the color development time, said gradients .gamma..sub.AR, .gamma..sub.AG and .gamma..sub.AB each being a gradient of the red-sensitive, green-sensitive and blue-sensitive silver halide emulsion layers, respectively, obtained after conducting the standard color development processing, wherein each of the gradients .gamma..sub.BR, .gamma..sub.BG and .gamma..sub.BB after the rapid color development processing within the range of from 30 seconds to 90 seconds of the color development time satisfies the fol…
