Re: Konica exposure with 29

I have been using the Konica 120 IR film and I originally started with an
E.I. 12 WITH the Red #25 filter in place.  After a few rolls I found that my
negs were too dense and I currently use an E.I. 25 with a Red #29 filter.
 The red29 is a 4 stop loss, while the #25 is a three.  So I effectively
reduced my exposure by 2 stops.

I us Tmax developer and times and temp for Plus-X.   I have not messed with
other developers as I figured this combo worked well, giving me wide tonal
range, sharp iamges and grain in line with 400 speed B&W films.  I can now
learn to control my exposure and filtering without haveing too many variables
to deal with.
