Nice and interesting set! 2, 4, and 8 could use some centering and/or straightening, but that would be a fantastic place to spend some time shooting.
I think the problem is that I’m not using an ultra wide angle lens correctly. I did some tests on random subjects and it’s really dependent on the angle I’m pointing it. It’s the edges that get so weird and distorted. 90% of my photography has been through a telescopic lensDefinitely need to correct the lens distortion. The lens software doesn't always work to correct but you can use perspective, warp or distortion control in PS.
It’s really amazing. Some of them are bigger than my house!Nice set and what an interesting place! I can’t imagine what those monuments must have cost.
