What is the best software for fixing wide angle distortion

[spiroq8]

I heard there is software that can fix distortion of wide angle pictures (and some not so wide). Does Canon software come with something like that tailored to Canon lenses. I have the Canon EF-S 10-22 mm which is a very useful lens but has a lot of distortion. I heard there is a software you can buy to fix that ... but maybe Canon already has its own solution? Also if Canon does have a solution tailored to its lenses, does it work better than the commercial sotware?

By the way I have PS CS3 and I read several sites which had info on fixing that such as this

But I was hoping that there would be a specialized software that can be specially tuned to each particular lens similar to how Noise Ninja where you have a profile for each camera. I was hoping I could use a software to just input the particular profile of my lens and it would give me a direct corrected output. This would be much more useful since I could batch process it instead of doing it manually picture by picture.

The type and range of a zoom lens' distortion changes with the focal length... so the software would have to work by focal length and not just apply a general correction to every image produced by a certain piece of glass. I'd be interested in hearing about other solutions but I'm pretty sure there is no automatic correction software that is quite so smart yet.

edit: I'm not sure I'd want to batch process all images like this anyway -- with super wides I will usually do additional cropping in post. Often the cropping in post will remove some of the edge distortion -- and every time you process an image (say to remove distortion) you are warping the base pixels of the image -- adding some pixel-level blur and loss of detail that can never be recovered. So best to only correct images that need it.

Try DXO optics...http://www.dxo.com/intl/photo

DXO is indeed highly regarded for the correction of geometrical aberrations, but if the wide angle "distortion" you are thinking of is actually the faithful reproduction of the perspective of the scene from the viewpoint of the camera with the field of view offered by the lens, you may be trying to "correct" something which is not a fault.

If you want to distort the true image to give the semblance of an image taken from a different distance with a different field of view, probably the best you can do is with something like the "spherize" or "pinch" distortions in Photoshop. However, I can't see any way of performing an accurate transform without having a complete three dimensional description of the scene.

Maybe someone else sees it differently.

I think the very latest version of Canon DPP has a lens correction facility, but it may just be for vignetting. I'm not at home, so I can't verify this.

Take a look at PTLens - works very well and is inexpensive ($15). It is delivered as both standalone and PS plugin. It has a database of lenses and cameras for automated corrections but manual adjustment is available as well.
