Thank you for a really awesome article ! 
My father started taking photos of our villages and the old folks back in the 1940's. He continued doing this until his eye sight got too bad. He is 92, almost 93. He has two books of his photos and the University of New Mexico bought all of his negatives about six years ago. He is considered to be one of the best contemporary American Indian Photographers in the US.
His work can be found : http://www.leemarmongallery.com/gallery.html
About 15 years ago. A pile of old glass photographic plates were discovered in the land-fill on Annette Island. They contained amazing photos of the early life at the Metlakatla village. The museum in Ketchikan hosted a showing of the photos which were "curated" by Mique'l Dangeli, who is now has a doctorate degree in Indigenous Art History.
I would love to see the movies and all of the work that  the folks have done to help preserve the language and culture. They were very forward in their thinking !
