Ever wonder why sunglasses manufacturers polarize the lenses? Polarization makes things looks better: skies more blue and clouds more white. Also, reflections are greatly reduced on shiny dark surfaces.

I took these photos today at Bay View Beach in Saco, Maine. Both of them are straight out of my iPhone 3GS’s camera without post processing. The one on the right was taken through polarized sunglasses.

I keep a circular polarization filter on my two most used camera lenses. With them I can dial in the amount of polarization I need for the look I’m trying to achieve. The difference can be dramatic, depending on the conditions.
