Don't you just hate it when you're trying to get a good picture of, say, a
beautiful European castle, and here comes the sun spreading its glory unto your picture? The next thing you know, you have that irritating glare line on the photo you were supposed to show off to friends. Argh. I hate that.
That actually happened to me, except the setting was on the beach. Of course, I quite anticipated already the glare and shiny reflections due to the water and all. That was when I just received my own camera and I did not know how to play about the polarizer or the
camera filter that could take away the glare.
It was only later that I learned about the types of polarizer I could use for my different cameras. Basically, there are two kinds. There's the linear polarizer, the cheaper filter, is great for my film camera. Then, there's also the circular polarizer, which is found on most modern cameras since they have the autofocus feature. Both filters work with a partly silvered mirror so that it can get rid of light captured by the lens. No wonder it's similar to
polarized sunglasses, huh?
