Using a desensitizer isn't required. According to Michael A. Smith and
others, the film becomes desensitized to anemic exposures of light after
half of the total development time has elapsed.

That may indicate that you could be partially color blind, not uncommon for
our male population.

Photography can frustrate us all at times.

Pretty valid since you are measuring the results of a process. Do you mean
would it be consistant? Repeat the test several times and measure.
My two cents worth,
Don Bryant
P.S. I've enjoyed reading Shannon's posts regarding film processing here and
on other lists. She has raised some interesting questions. I don't think her
questions about the testing reports being vague and confusing from the VC
Store are that unusal. I have a friend that tried them out and did not
receive an answer about what the suggested film speed either.
