Any interest in Mathematica code for Sanity Check ? 
Harold Cohen  20:11 15 Jul 14 
Since my darkroom is a changing bag, I am testing my understanding of BTZS by doing a bastardized exposure/contrast test and analyzing my data with Mathematica code I am developing. So far (1 roll of Ilford Delta 100 70 deg D76 1-1) produces a H-D curve that fits well re BTZS's sample plot.
The problem with working alone is that it is easy to go off in a stupid direction and not see it! Is anyone interested in interacting?
