Help w/aspect of 12mm lens in PS

[FatDaddy]

I shot this with the 12-24 Tokina and think it needs to be fixed a little (seems squeezed). What is the best way to do this? I have Photoshop, but am not sure what to do next beside just expanding it by eye (which makes me nervous since I am judging it by eye).

Any thoughts and suggestions?

Thanks,
john

In PS do filter, destort, lens correction. If you ignore my crappy crop I did a +7 adjustment on it. You don't really want to go much further than that in any direction.

Cool beans.

Thanks Dan.
