Thanks- I really enjoyed your pictorial too

.
Short answer- Nikon and Aperture.
I'm a complete novice actually, and don't have a "system" down quite yet for post processing. I mainly go with what looks right. I try and adjust curves- very cautiously at this time. I'm reading a lot though, and there is no shortage of inspiration out there and on this site.
I use a Nikon D90 or D40x with either a sigma 150mm or the awesome (and cheap!) Nikon 50mm. If traveling or paddling I have a Nikon 18-200mm, but prefer the prime lenses for landscape stuff.
I am trying to learn/getting my feed wet (just the tippy-toes) with multiple exposures, auto bracketing, etc on some of my images-again, I don't consider myself an expert, but in this area, one person I have tried to learn from is Nepalese-American photographer Mahesh Thapa. Check out his stuff at
www.starvingphotographer.com. Simply stunning.
LostCanadian on this site turned me on to hand held grads. I like his work a lot.
