RE: [APML] Fuji HQ100 film tests - the Results

["Chris Schur" <cschur@cybertrails.com>]

Steven,

You should not hyper slide film.  The reason is the Dmin is raised thus
making what was a limited dynamic range - 4 stops- to like 3 stops.  The
background gets pretty nasty too, usually some horrible red or green color,
making color balance very difficult.  Better results can be had by pushing 1
or two stops.

No Jim.  I haven't tried hypering the 100f either.  Anyone tried this?  -s
