Well to give one quick example, were all the test films developed to the same contrast?
Again, I'm not saying great work can't be done with stand-developed negatives. Of course it can.
All I'm suggesting is, if you were a Rodinal user and were considering using stand development, and you came across this thread, wouldn't you want to know what kind of tonality to expect? What kind of film speed to expect? What kind of local contrast compression (if any) there is? Etc.? Wouldn't you want to know how adding Sodium Chloride changed things vs straight Rodinal?
