A color negative photographic element is disclosed comprising at least one light-sensitive image dye-forming unit containing a plural number of silver halide emulsion layers having different levels of photographic sensitivity which are spectrally sensitized to the same color region, wherein the silver halide emulsion layer having the highest level of photographic sensitivity of the unit comprises at least 40 wt %, with respect to total silver halide in the layer, of a first silver halide emulsion comprising silver halide grains with an average equivalent circular diameter represented by ECD.sub.1 and from 5 to 35 wt % of a second silver halide emulsion comprising silver halide grains with an average equivalent circular diameter represented by ECD.sub.2, and the silver halide emulsion layer having the second highest level of photographic sensitivity comprises at least 40 wt % of a third silver halide emulsion having an average equivalent circular diameter represented by ECD.sub.3, where the ratio of ECD.sub.2 :ECD.sub.1 is at least 1.6 and the ratio of ECD.sub.1 :ECD.sub.3 is at least 1.2. The invention results in increase in speed (or light sensitivity) of a light-sensitive silver halide photographic material while maintaining good graininess in the mid- to high-exposure regions.
