    Maybe it's because it eliminates the need for a complany to offer a 100 and a 200 speed film. 160 is pretty much in the middle.

    Wouldn't 141 speed be closer to the middle of 100 and 200?

    It's twice as close to 200 as it is to 100...

    For me with a film such as Portra 160 serves the purpose of a 100 and 200 speed film. If I need faster I go faster.

    They're rebels without a cause. Society wants their film speed to be a multiple of 25, but they say NO.

    Before there was Portra at ISO 160, there was Vericolour III at 160 (IIRC). Before that, there was Vericolour II which was ASA 125 (IIRC).

    Just progress, I guess .
