film speed adjustment 
phil sweeney  11:50 16 Sep 02 
I have a question regarding a negative development test. Using a zone board I achieved these results: zone I = 0.17, zone I minus 1/3 stop = 0.14 and zone I plus 1/3 stop = 0.21. The zone I speed is 40. If I want to increase the speed to 32, would not the resultant zone VIII density at 32 be the results at 40 plus 0.04?
