Thanks, Dave. It seems to be losing less in real estate than LR auto correction. What did you do?
Ah, that would be a secret..!
No of course it isn’t
All I did in PS, was to first try using puppet warp, but that just seemed to smear the detail, so I Ctr;+Alt+z’ed my way back out of that, then I duplicated the background layer (Ctrl+j), put a selection over the part of the shot that seemed to be effected by lens distortion on the main part of the building to the right, but that also included the top right and all way down to the bottom of the shot, to end up with a selection for about a third of the shot on the right. I then used Ctrl+t for transform and skewed the selection on the upper layer to the left (Ctrl+shift+ top middle transform handle) until the building edge to the left looked straight, then using the bottom right corner handle with Ctrl+shift to pull the right side of the building straight from the bottom. I then applied a mask to the corrected upper layer and blended it back into the background layer in a way that kept the best of the detail form both layers. I then cropped out your sig from the background layer, as it had now moved and distorted a little on the upper layer and pasted it onto the upper layer after doing a selection and content aware fill over the old distorted sig first to remove it. I then flattened the image, selected all (ctrl+a) and levelled out the horizon by pulling the top left hand handle with Ctrl+shift to the left a little and then stretching the bottom left corner down a little to square everything back up.
Not a great explanation I know, sorry! But I suppose it does go to show that the old 'do it yourself' methods can still beat the 'auto' methods some of the time
