Thanks for the discussion. I'll follow up on Perry and Cramer.
Yes, your book on Cradle Mountain is the area I was referring to. It's an area I've done some shooting too.
The absolute master of Tasmanian Wilderness photography is Peter Dombrovskis. His studies of the wilderness have had huge political impact as well. Google for him, I think you will like his work.
I understand how you are using long exposures for simplicity - it's why I was wondering about just how long your exposures are. Are you using density filters as well?
My own style is all over the place from Street photography to Landscapes. Abstraction and ultra simplification are passions of mine as well and there is one of mine in this mood over in the Abstract/Experimental thread this week.
Your shots certainly caught my eye. Looking forward to seeing more.
