I shot the photos on vacation, so I can't redo them now!
I thought the perfect level panning was needed to make merging easier, before nice software that stitches automatically. But... maybe I should do a lens correction to the image before merging? (Does Photoshop's feature do that? I would think so.)
The horizon was not undulating. It was a neat curve.
Here it is with the filters turned off:

that might be affecting me here. But I don't need a perfect reproduction, but something artistic, to show that you are standing on the edge of the precipice. I don't like the extended "apron".
Do you mean the tools are better at stitching together with the desired perspective to begin with, as opposed to having to clean up after Photoshop's Panorama Photomerge? When I read up on software, Photoshop built-in was one of the top choices! I guess it got points for "easy to use", and I want something with all the knobs and buttons to play with. [edit: maybe Cylindrical would do what I meant, instead of Auto.]
Hmmm. I tried using "Arrange" (only) on the same set, and it's not a nice two rows like I thought. PS did a great job of making sense of it, actually! Here is a better grouping, just one row (so no foreground or bottom of the middle distant part).

I think a piece of advice would be to know how the photos really fit together just plainly, rather than eyeballing separate images in a library view.
