Abstract:
A silver halide emulsion comprising silver halide grains, wherein at least 30% of total grain projected area is accounted for by tabular grains having an aspect ratio of 5 or more; said tabular grains further having dislocation lines of 30 or more per grain in a fringe portion of the grain, and said tabular grains each contains silver iodide, the content of which gradually and continuously varies from a center to an edge of the grains so that each said silver iodide content variation in a direction from the center to the edge is within a range of âˆ’0.03 mol %/nm to 0.03 mol %/nm, where each said silver iodide content variation is a difference of silver iodide content between two adjacent measurement points divided by a distance therebetween, each said measurement point being at an interval of 5% of a length of a line which is drawn vertically from the center to the edge of the grain.
