Alfried Stieglitz Documentary
Ansel Adams Documentary
I haven't been making night images, but rather watching documentary about those well known classic artists, watching their documentary is like a brainstorming to me, I don't think I will be able to absorb all of them.
We all love to learn about photography techniques and rules, as it is important to know the technique in order to take things in control and work rapidly. But watching this kind of documentary is truly eye opening as we can study about their thought and approach on photography art throughout entire of their life.
Interestingly though, while both of them are not night photographers, they have taken impressive night photos that should be studied by night photographers.
Be warned, it's quite a lengthy documentary.
