I am new to this forum, but I can see that it will take some time to dig into this mountain of knowledge.
I teach film classes with an International School in Hong Kong for primary students (The Harbour School) #THS_Photo_Club (Instagram) and do other various photographic activities. I also host a blog on my website. I have about 7 film cameras and one digital.
I look forward to learning and contributing to this vast universe of film photography knowledge.
You live in a fascinating place for a photographer.
I know HK quite well, my visits were during the 90's.
