We've been having some nice sunny weather, so last weekend I dug out my good sunglasses (Maui Jims) and suddenly the world looked wonderful. Deep, clear, gorgeous colors. And I thought, "if my eyes like good polarized lenses so much, wouldn't my camera like them too?" The result, of course, is that I now think I might be in the market for a polarizing filter or filters, depending on which lenses I decide I'm likely to use for landscapes, and how much the price hurts. Am I right that a polarizing filter will do the same thing for my pictures that good sunglasses do for my eyes? (Except for the "looking cool and fashionable" part, which frankly I don't.) Is it useful for anything other than making landscape colors pop on sunny days, and reducing reflections from water? I haven't found myself taking a lot of pictures of water, but who knows whether that will change. What should I keep in mind when I'm shopping for one? I suppose I'm looking for something in the "acceptable" range. I don't have pro quality lenses (or pro quality skills), but I don't want to slap something on my camera that will make my pictures even worse than they currently are. Specific recommendations -- either to buy or to avoid -- are welcome! I've read through some threads here, but they tended to get acrimonious, and weren't particularly helpful to me. I don't want to reopen any cans of worms -- just asking for a little advice for a clueless noob. Thanks!
