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


That would be "I shot a roll" in English.

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?


Seems to me that's all you *can* do; otherwise, you're going to
completely lose whatever shadow detail you have, or get a low-contrast,
difficult-to-print negative.


I do not know wether this development (N+2) would be wrong because the
scene is very dark, with wooden figures that come out of the dark
background. I Will try it again. Thank you. Regards H.K.

If you are in fact able to try it again, I strongly suggest that you
bracket. If your base exposure is 200 sec (over 3 minutes!), try in
addition to 200 sec exposures of 400 sec and 800 sec.
