Perspective Issue

[Royal Jayhawk]

Hi Damien - 

I read up on your article on perspective corrections and am just having a heck of a time fixing this image.  The building has a lot of vertical lines that I am trying to align to a grid so that all of the vertical sides of the windows and building match up to the vertical gridlines.  I also drew a line on a new layer from the left edge of the roof to the right edge of the roof and noticed the whole image is bowed like a "U".  I think I understand how I would pull the image if it were in front of me in the format of play dough... but I am not sure how to achieve my desired result in photoshop.  Haha.  

Thanks!

Hi Kris, may I see a screenshot of what you've tried so far?  With the grids turned on and the transform handles active?

Bah!  I gave up and trashed my edit earlier before I posted.  I'll try again and post my progress for your guidance.  My wife needs our computer for a bit tonight for work, so if I cannot post something tonight, I for sure will tomorrow.

I just tried it, and got no "U" shape.

I just used Perspective, then Skew.

Hi Damien - 

Got back to this one tonight.  I think I got the perspective correct but didn't use skew because this looked right to me.  Do you think this needs skew?  Admittedly, I have not dabbled a ton with perspective tools, so this has been a learning experience.

Thanks!

Oh, right.  Yeah, you used perspective on both axes, so no, you don't need skew.

I only used perspective on the x asis.
