Jeffrey, are you saying that the one drop method will produce similar
contrast adjustment through the use of a lesser concentration than that
which is used in the two solution method???
I'm only trying to understand how the chemistry is different - we all seem
to agree that the answer to the quiz is something just greater 16%.
However, you are saying that a solution of .5%-2% will effectively render
the same contrast adjustment and therefore the effective equivalent
concentration (using a 1% norm) is 1/16 of .33%.
Pardon my ignorance.
Many thanks,
Nick
