hello

yesterday, in a dark church, where i photographed some
dark choir
stalls, i underexposed a kodak 125px (3 stops). normally i
push it to
get good grey values, which is not so bad because i
shooted a roll of
120-film (6x6). but when i made the photographs i exposed
very long time
so contrast will be enhanced a lot because of the effect
of reciprocity.
i exposed 45 sec instead of 200 sec.

normally i develop in kodak hc 110 - b, n+0: 6,5 min. n+1:
9 min, n+2
12,5 min. what do you mean? should i take n+2, loose 2
stops, so that
zone v falls down at iii, whith a contrast of 3 zones,
enforced by this
long-time-exposure?

regards h.k.

First of all using a developer like Xtol, T-Max or
T-Max RS, DDX, or Microphen will gain a bit of speed over
HC-110, perhaps 3/4 stop. Increasing development time to
"push" film just increases the contrast. Where the exposure
is mostly on the toe, which has lower contrast than the rest
of the film curve, the increase will make this low contrast
image more easily printable but will result in very high
contrast for anything which has received more exposure. Your
exposure error is around two stops. If its based on the
normal film speed you can probably pull out printable
negatives but forget the zone system because the tone
rendition will be a bit distorted by the reciprocity failure
plus you are getting very near the limit of exposure which
will register on the film. Again, I suggest using a
different type of developer for this roll and trying to push
a couple of stops. Plus-X responds fairly well to pushing.
