I think they are all good pics but #3 would be a wall hanger for me. Love the brilliant blue and the details in the clouds and the surrounding rocks give it a built in frame. I might clone out the "UFO" because it is a little distracting. It looks a little surreal and makes you wander for a sec if it is a digitally alterted scene; you can tell it is water but it makes you pause long enough to look carefully and I think this gives it a good deal of interest.
I like #7 as well but I think it may have been a tad better with a neutral density filter and a longer shutter to blur the water.
Thanks! I would have loved to try that, and actually thought about doing it, but I was worried I couldn't get a sharp picture since I don't have a tripod yet. I'll probably go back in a month or so, and I hope to try that than.
How long of an exposure does it take to get that effect?
