ABSTRACT:
A method for forming an image is disclosed, comprising imagewise exposing a negatively working silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer with light having a wavelength of from 460 to 600 nm and containing substantially no light having a wavelength of 360 nm or less, said emulsion layer containing at least one sensitizing dye having an absorption maximum (.lambda..sub.max) at a wavelength of form 450 nm to 580 nm, and said emulsion layer or other hydrophilic colloidal layer containing at least one hydrazine derivative. The method provides an image having excellent image quality either in enlargement or reduction work without causing reduction in sensitivity or inducing black pepper.
