Navajo bridge is
the only roadway that enables travelers crossing the Colorado
River's Marble Canyon to access Grand Canyon North Rim. The
picture was taken by a wide angle lenses and thus the bridge
appears to be curved. At first I attempted to straighten the
bridge using Barrel Correction, but later I found that it is
more interesting to go to the opposite way. Instead of fixing
the curve, I used the Pincushion Effect to "bend" the bridge.
