I'm trying to learn some new Photoshop skills. Here is a picture I took a while back that has a serious Keystone problem. For anyone that has some time, please try your best to fix this and then post the steps you used here. If anyone else has a photo they would like people to practice with, feel free to post it here as well.

I really don't think you're going to "fix" that one. The single building (well, a sliver of another one) has a vanishing point that is just too strong. Anything you do to try to remove it will end up making the tower look absurdly squat. I'll dig up one that I fixed and see what you think.

Well that explains why I am having such a hard time with this!!!

I'll play with your photo and see what I can come up with.

Thanks!

So here is my attempt. I used the Free Transform option under the Edit menu to do this. I think the buildings turned out ok, but I didn't do the person standing there any big favor.

Yeah, the distortion in that one was a bit extreme too. Even the buildings look a little unnaturally squat. I'm not at my main PC now but I'll take a shot when I get back.

Here's my quick try.

Lost a lot in the crop, though.

Nice job stretching this back out so it retains its natural look. I've used slight corrections in a few images, but never one that was so bad to start with. I'm not sure what the "best practice" is in how much to correct. Where are Bear and Kirbic when you need them??

You mean like this?

Here is my shot at it. I used 'distort' in PSE 4 and a few more details in the details section.

Here's another good subject. This photo is an excellent example of a very good fix done simply by the edit/distort/perspective commands:
