| I just bought a wide angle lens for my camera and it kind of distorts buildings by making them point inward. Is there a way to correct that with the camera or with photoshop? |

If I'm not mistaking, it sounds like you're talking about pincushion distortion... I don't think you can correct that with the camera... generally the higher quality lens you buy, the less barrel/pincushio distortion...
In Photoshop, try Filter->Distort->Pinch...
Enter a negative percentage to push the image outward instead of inward and see if that helps...

If you shoot a lot of architecture or plan to, you can buy a perspective correction lense. It is a split lense and can do perspective corrections while shooting.

Or else see the above links. Photoshop is the most obvious option..
Hope this helps.

Shift lenses are great having had the chance to use them myself, but they are so expensive, unless all I shot was architecture, or was filthy rich, I would never by one :)
If its perspective that's causing your distortion, there's a Perspective correct option in Photoshop 6.0 and greater....
Select a cropping area, then Edit -> Transform -> Perspective...
You can then move the top bounding corners outward to correct buildings that slant inward...

you can resize/crop htem in photoshop and check the 'perspective' check box to redress lines.
You can as well 'defish' using panotools. Available for free and that would show as a plug in in photoshop. You mind fight a little to find the right values (there is 2 anfle of view parameters to give) bu tother than that, it works like a charm.

Best advice - don't stand so close to the subject, the effect will be less noticeable.
