A photographic camera film comprised of at least one radiation sensitive silver halide emulsion layer unit and a film base in a roll satisfying the formula <IMAGE> in which FBT is the thickness of the film base in micrometers ( mu m). L is the diameter in mu m of the film roll; SD is the spool diameter in mu m of the film roll; and TU is the number of film turns in the film roll; wherein at least one emulsion layer unit is comprised of a radiation sensitive emulsion is disclosed containing a silver halide grain population comprised of at least 50 mole percent chloride, based on silver, wherein at least 50 percent of the grain population projected area is accounted for by tabular grains bounded by {100} major faces having adjacent edge ratios of less than 10 and each having an aspect ratio of at least 2.
