Oh, such great arches and lines. :) You are correct, the perspective is slightly warped. Not your fault, it happens with these wide angle exposures. Do you use Lightroom? If so, I can offer some suggestions on how to fix perspectives in post-processing. If you don't, then I am not sure what to tell you. Also, fyi, you stood in the middle of the space while taking the shot, so congrats to you. :) Regardless, a beautiful space.
Lovely arches and so many! It definitely leans left but the only way to correct it is through a program like Lightroom that has lens correction. You are quite straight on the left lines of the arches -- probably the lean is from where you were standing. Were you centered?
@darylo@rosiekerr@taffy I did try to level and have tried again today. I do have LR. I have tried to adjust for the lens, but I don't have that specific lens in my LR. Perhaps I needed to keep at it to frame it better. Just learning this 10-20 mm lens. I posted a different angle for today. It has different issues!
