Your question and request will prompt me to write a long-overdue journal article on moth photography. The answers to your query are “out there” but widely scattered. My Texas mothing pals and I have been coaching individuals when the opportunity arrises (at bioblitzes, etc.) and I offer suggestions routinely in comments on observations, but that’s obviously not getting out to the wider population of moth enthusiasts. When I get that journal entry ready, I’ll post a link to it here (and probably elsewhere).
I’ll take this opportunity to point once again to a book review I did of Dave Barker’s “Moths and Mothing, Featuring The Moths of the Devils River”(@ptexis). He has an excellent chapter on moth photography.
