I was just listening to The Art Of Photography video pocast by Ted Forbes
http://theartofphotography.tv/
It is a great source of info on the art photography world
I listened to the specific video podcast on the Fine Art specifically below and have copied the links from this podcast
https://www.youtube.com/watch?v=_Pa2XgsJS3I
It contains links to a trove of the greatest Photographers that are shown in galleries, both old masters to contemporary fine art.
I would recommend this as a great source for inspiration.
