Correcting Perspective Distortion

[Myphotosoft]

Sometimes camera lens distorts image perspective. The effect can be easily remedied with Photoshop CS2 Crop tool. [details]

Thanks. An excellent demonstration of an often overlooked feature.

Thanks. I had noticed that check box there before and had wondered what it was for. I immediately went to play with it. By the way it works in CS too.

At the risk of stealing your thunder, I might add that making a copy of the picture to be straightened and correcting it with free transform is a nondestructive way to make the correction. That way if you goof, as I often do, you still have the background layer (original) to revert to. This technique has helped my cropping and straightening tremendously.

There is also the Distort->Lens Correction filter. It allows for vertical and horizontal perspective as well as barreling corrections. It also has a scaling capability to increase the size of the corrected picture to fill in the "lost corners" that are often the result of standard rotation.

Thanks for introducing more clarity. It's something so automatic, I didn't think of
reminding others of this step
