ABSTRACT:
The present invention provides a silver halide photographic photosensitive material which has a printability from color negatives and which can be used as a variable contrast printing paper. This silver halide photographic photosensitive material comprises a support and at least one silver halide emulsion layer provided on the support wherein when .gamma. (gamma) values of characteristic curves obtained by exposure through filters having a transmission maximum wavelength at about 430 nm, about 540 nm and about 700 nm are indicated by .gamma..sub.B, .gamma..sub.G and .gamma..sub.R, respectively, the following inequalities 0.3<.gamma..sub.G /.gamma..sub.B <0.7 and 0.3<.gamma..sub.G /.gamma..sub.R <1.0 are satisfied. Furthermore, an exposing method is also provided.
