Thanks! And I'll have to look into that tool.
Do I understand correctly that it's only for the CC?
I'm one of those oddballs who still uses the software native and loaded onto my computer.
I don't blame you for not going the subscription route.
I think the Guided Upright Tool is CC only but the Crop Tool in PS will get you pretty close. ( Check the 'Perspective' box in older versions or use the Perspective Crop tool in more recent ones ).
It's fine as it is though: I'm one of those oddballs that needs perfect verticals in an image - like the real world is anything like that.
