In an upcoming tutorial (look for The X-ray Brush when the Tutorial Publishing System is functional again) I retouched a photo of a church. As a final touch I wanted to correct perspective and used the Crop tool. It worked flawlessly -- I thought. When I compared the images side by side, it turned out the Crop had metamorphosed Legolas into Gimli! 
Instead of a tall, stately church I got a squat building of sorts. The height in pixels has been retained, but the ratios between the various levels is weird. It looks like a "funny mirror" in a tivoli.
I have attached an image of a ruler. It seems to me that the change in height ratio follows an unnatural curve. Real life is not as dramatic as this. This looks like an 18mm Wide.
Why? Is there a better way?
