HDR with Photoshop

After playing around in Photoshop today, I discovered the HDR Toning option!  I've always loved the appearance of HDR, but the few attempts that I made to try and create my own while I was taking a photography class in college were not successful. :(

Jump to a today: I figure out that Photoshop gives you the ability to quickly and easily give your photographs the HDR effect.  I tried it out on a few of my pictures from Peru.  So far, I've just been playing around with the different settings to try and make a somewhat interesting picture.  At some point I'd like to actually research the process more to know exactly what the crap I should be doing...

Anyway, here are the "before and afters"
