My wife and I went to Parke County Indiana on Saturday, October 25, 2014 to photograph covered bridges and rural Indiana scenes with fall colors. Parke County, Indiana, is known as the Covered Bridge Capital of the World with 31 covered bridges.
While photographing Phillips Bridge, I saw an opportunity to include my Jeep in the picture and take both non-polarized and polarized images. As can be seen, the reflections in the Jeep's metal and windows are greatly reduced while the saturation in the reds are increased as well as in the side of the bridge, the grass and tree leaves.
These Photos were taken as camera RAW images and processed in Adobe Photoshop CS5 using identical color balance and adjustment settings for each so an accurate comparison could be made.
Following is the camera's metadata recorded each time I tripped the shutter.

The difference in shutter speeds above, is because the polarized image required a slight adjustment to compensate for the slight loss of light being transmitted to the sensor when the front ring of the polarizer was rotated.
These images were taken with a full-frame Nikon D700 camera mounted on a tripod with an AF-S Zoom-Nikkor 24-120mm F/4G ED VR lens with a B+W circular polarizer filter attached.
