    I think Vaughn is right when he says developing for longer than the recommended time probably doesn't do much because of the reasons stated. In fact, it may reduce density in the negative and make the positive darker, as it could allow more silver to move from the negative to the positive.

    All please genuflect... a reading from book of St. Ansel

    Polaroid Land Photography, pg. 228.

    "Effects of development changes: Essentially none, since the print and negative develop to completion. A very slight decrease of the base-plus-fog density of the negative occured at 60 second. Insufficient development must be avoided, since it produces discoloraton of the negative when it is exposed to light."

    "Tested optimum development time: 30 seconds at 70 deg. F"

    "A very slight decrease of the base-plus-fog density of the negative occured at 60 second." That actually sounds nice...

    At least with LF landscape, a bad day of photography can still be a good day of exercise.
