OK - you took a photo and the room is leaning or tilting. What do you do? Skew it!

Before starting, I find it is easier if I enlarge the "canvas" to gain some working room. Grab one of the edges or corners of the window holding the image, and drag outward.
Next:
In Photoshop Elements 5 hit Select -> All. Then hit Image -> Transform -> Skew
In Photoshop Full Version hit Select -> All. Then hit Edit -> Transform -> Skew
Grab the lower right of left corner of the selection box and drag outward. Grab the opposite corner and drag outward. Keep dragging until the predomoniant vertical lines look straight. Hit Enter to finish and "Apply the Transformation".

The Skew tool is a very easy tool to master. Learning of its existence, and learning where to find it are the difficult steps.



Cheryl ~ no excuse to get skewed anymore! Haha couldn't help myself. Good series, very helpful, thanks!

Cheryl,
Once again, I thank you for the handy tip! I've been doing it the long way of rotating % by trial and error.
Lucky :)
