Well, good grief, Ron. No stones from me. The Light Farm is dedicated to collaborative and cooperative learning and teaching (although, in truth, I can get testy about obfuscation.) You have been invited to participate many times. Mark's articles are valuable contributions. I wouldn't have posted what I did except to address as honestly as I know how the comment that there is "silence" on the subject of dry plates.
I still don't see that you understand the influence of the repetition of the word "I" in so many of your posts about emulsions. Please consider that it might be daunting to newcomers. Also, I draw your attention, and perhaps your memory, to this thread, http://www.apug.org/forums/forum205/...n-house-3.html, particularly post #23.
