Wondering why the image looks concave after correcting for verticals in LR Classic. I'll attach a before and after perspective correction. Both images have the correct camera and lens corrections applied. Look at the top of the building for the concave effect. The horizontal line ofthe top of the building should be straight but it's not.
I have noticed this curvature on some of my images also, but don't know how to fix it.
Is the root cause of this problem your issues with selecting the correct lens profile, described in your other post?

It's more difficult to see, but the before image has concave horizontals too. You can see it clearly on the right side. So this is probably not a perspective correction issue, but a lens profile that is less than perfect.
Good point! I guess it gets exaggerated when corrected for perspective. I'll look into the lens profile issue. Thanks!
