Tilt Shift iPhone Photography

OK, so I am a little obsessed with the tilt shift application for the iPhone. I checked out Silver Creek today and it was cold with a slight but raw east wind. I did not take a single image at the creek. I was hoping for a final shot at a few baetis images and did not see one. Browns are still spawning and nobody was around. I then checked out Cedar Bend Preserve on the Wood. I took three images there with the iPhone and edited them with the tilt shift generator application. That's it...  Keep in mind while the title of the application says, "tilt," the application is only capable of a shift effect.  Additionally, the app lets you control saturation (you can desaturate to black and white), contrast, brightness and vignette.
