I like the first shot. You and I differ in framing on some of the
others though. However that is just a matter of preference (like the
rock in the foreground of the one -second shot?, I'd have left that
out)
I hear what you are saying, however.. I am trying to capture the many angles of Mesa Arch during the changing light of sunrise. Unfortunately for photogrpahers, not every angle at Mesa Arch is going to have an unobstructed view of both the Arch and of the canyon floor below. I have literally a hundred shots from that trip alone (not counting the trip in May) with unobstructed views through the Arch with the changing light but posting those would have been boring. I also have many with these kinds of views. For the purpose of my memories of the trip, the semi-obstructed views tell the larger story.
One of my favorite shots at Angel's Landing in Zion NP was taken with the Zeiss 21mm @f5.6. F5.6 is the sweet spot for the 21mm Distagon across the frame with the right subject matter. Most of the frame was far enough away that f5.6 handled the DoF well except for a bush in the front left which was too close for f5.6 and was a bit OOF. When I posted the image here, someone commented about that bush. I went back and looked at my f8, f11, & f16 shots and just felt that my original instinct was right for me. Most of that frame except for this one thing was sweet at f5.6, f8 didn't bring the bush into focus, f11 helped a bit but the center no longer had the crispness of f5.6, and f16 was clearly degrading the center (degraded relative to f5.6, not that the frame was so degraded as to appear that it came from a P&S).
btw, I always shoot a scene with f5.6, f8, f11, f16 so I have my choice of DoF with each.
The last shot bothers me. What were the settings? There is a lot of
noise in the sky of it, and I was curious if that is from the camera
or from sharpening the entire image instead of just the rock
formations. I'm learning here too, and would like to know which it is.
If you can bear with me until next week, there is a story to tell. I just needed to bring forward this one photo for my Mesa Arch "Exhibit".
btw, I will have Internet access next Sunday from my hotel room, for the rest of the week I will be at the Grand Canyon North Rim and other points of interest where there is no Internet access. If you could be so kind to get this thread started on Sunday so that I can post the aforementioned story and images.

I'll be meeting Ben Egbert at the North Rim on one of those days.
