I just finished the one on Patrick Brown, Trading to Extinction. The material within and the quality of video is great! I will keep on going through these this weekend.
On a side note: The video also touched on a little bit of the atmosphere within the photographic publishing industry, and its relationship with documentary/photojournalists nowadays, and the difficulties the photographer had with getting his work out just because of the subject matter and the fact that he shot it all in black and white (he says that had it be color it would have been picked up quickly). Though all in all, there was a positive outcome as I discovered with further reading using a new startup model for crowd sourcing pre-paid printing runs, somewhat similar to the kick-starter crowd sourcing venture capital system. His book did become fully funded for printing.
