Mitch,
Not really anything new here compared to the previous posts, but this is a real world example of when I had to resort to "stand" development to get a printable negative.
I once accidentally overexposed Tri-X by 3 stops (I forgot to set the ISO rating on my meter after shooting a different film!) in a scene that was normal, meaning that the brightness range was normal and normal development was called for i.e., there was not 3 stops worth of latitude given the contrast range of the scene (remember, film "latitude" is very dependent on the brightness range of the scene; the more gray scale that is used to expose the film, the less latitude there is for exposure error).
To deal with it, I developed the roll (120) in highly dilute HC-110 i.e., 1:119 from concentrate for 22 minutes and I reduced agitation from the standard cycle of 4 inversions in 5 seconds time every 30 seconds to 4 inversions in 15 seconds time every 3.5 minutes. The negative turned out good and printable. This would not have been the case if I had used a normal development time and a normal strength of the developer; normal dilution would have had way too much developer activity in the high high values of the way overexposed negative, as well as the low values, making the the negative so dense at to be, commonly known as, bullet proof. It called for a weak dilution and longer development time, but the key to the succes is the agitation cycle. Allowing the film to "stand" in contact with a weak dilution for a long time will exhaust the developer activity in the more exposed parts of the negative while the less exposed parts will continue to develop. In the end, the goal is to have a negative with a density range that is still within the printable density range of the paper where detail can be presented in the final print where desired.
Hope this helps.
