How to correct wide-angle distortions in Photoshop

Hi.

I just got back from a trip to Europe and have a bunch of architecture shots I

took with my wide-angle lens from the ground. There is a lot of distortion

where the buildings all seem to lean in toward the center from the outsides

going up. See attached. What is the best way to correct this in Photoshop CS2?

Thanks,

Matt

perspective correction option in the crop tool.

Thanks. I also read about "Transform/Skew". Is that better or worse as far as quality loss?

BTW, this is not a wide angle distortion but comes from tilting the camera<br>Regards<br>Martin

They all work the same way as far as quality goes.

 

For best results, use a shift lens. But then you need a tripod and are limited to certain focal lengths.

It's best to plan for use of this tool when you're making the photograph by including more in the photograph than you plan to print. As you can see from Ellis' correction, a little of the original photograph is lost at the bottom and the sides because of the correction. Not that it's a big deal with this particular photograph but if the edges were important to the photograph it would be.

Ronald is right about the shift lens, the 24mm by Canon is what I use for architecture. You

can, if necessary, shoot without a tripod while using the shift if the parameters are within

normal hand-held requirements, but it requires making last second adjustments through the

viewfinder to align the verticals properly.

Here is my 5 cents. I always use Distort tool instead of Skew.

Shift lenses are expensive. Obviously this is a vacation shot, and you do not want to be switching lenses all the time just to shoot one photo. Next time, just make sure to shoot more of the panorama, so you could crop it later. You have to crop it no matter what technique you use. Cheers
