That was a nice article, @Xairbusdriver, and a good review of techniques for varying conditions. @Edouard, I'm not sure how you got a point-n-shoot bias from the article. She was talking about using depth of field, adjusting shutter speed and aperture, using wide angle lenses, and did mention using a polarizer. several things she mentioned are not features available on basic P&S cameras.
I dod have a couple circular polarizers, but use them sparingly. While they do make some scenes quite dramatic, their use is sometimes too obvious and artificial. Like any technique or tool, it has its place.
