Photographic camera film containing a high chloride tabular grain emulsion with tabular grain {100} major faces

A photographic camera film comprised of at least one radiation sensitive halide emulsion layer unit and a film base in a roll satisfying the formula ##EQU4## 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, where, when the film is rolled on a spindle, the spool diameter is the diameter of the spindle and, when the film is rolled on itself, the spool diameter is the inside diameter 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 containing a silver halide grain population comprised of at least 50 mole percent chloride, based on silver, at least 50 percent of the grain population projected area being accounted for by tabular grains (1) bounded by {100} major faces having adjacent edge ratios of less than 10 and (2) each having an aspect ratio of at least 2.
