Simply Magical

The last camera filter that I will mention is the polarizer. This filter is used primarily to reduce reflections and darken a blue sky in scenic landscapes. Even though the polarizer works like magic, it needs to be used with care. It is easy to over-polarize a sky and make it too dark. Also with a wide angle lens the sky is often not polarized evenly making it look unnatural. If you forget your polarizer, there is a Photoshop trick that will somewhat simulate the effect of a polarizer to darken the sky. That's a subject for another time.
