If you wonder why nobody replies it's just because we are green with envy. Beautiful pics! Hope you shoot some video as well, you could make back the money through a stockshot site in no time.
BTW, I am taking videos, but I am new to the medium. I have been taking photographs since I was a teenager. For many years I shot 4x5. But video has been my kid's plays with a camcorder. Almost all my videos with the GH1 have been keeping the tripoded camera still and let the waterfall, or whatever, do the moving. When I pan it looks jerky. But I am having fun.
There is a Davis and Sanford model and a Monfrotto by Bogen both for around $70. My whole tripod only weighs a little under 3 pounds. I'm not sure it can handle the weight of a fluid head and the camera. I just got the tripod for hiking. I'd hate to get a new one.
Also, Google Shopping returned a lot of fluid sunscreen for my head as well. Not a bad idea on my hikes. I don't have much hair but I always ware a hat. Ah, the joys os searchology.
Today I was on Trail Ridge Road. Great views and I got to meet some of the locals.
I learned something interesting. I knew that mjpeg was limited to 2GB and that the length would depend on the size and how much the image changed. But I had no idea how much. On HD (720p) it usually takes segments of a bit over 8 minutes. I took a video of the clouds slowly changing over Longs Peak (see 1st image above). The video lasted over 21 minutes.
