I love outdoors and love taking landscape photos. However, I take 99.9% of my pictures with a polarizer. Other than evening shots, is there a reason where a polarizer is not always recommended for landscape photography? When do you not use a polarizer? Cloudy days, sunrise, sunset? |

It seems to me that there are two basic reasons to use a polarizing filter. First, to reduce reflection. Second, to deepen the contrast in the sky and produce deeper blue skies. One additional reason would be to use the polarizer as an ND filter. You are paying a price when using the filter. Mainly, it is forcing you to use a slower shutter speed or wider aperture. Also, many believe that any time you put a piece of glass between the subject and the film you reduce image quality. You have to decide if what you are trying to achieve artistically is worth the price you pay. |

If you are going to take several images to stich into a pano you might want to take off the polarizer. In my experience it makes matching the images very difficult. |

ultra-wide lenses sometimes do not take well to polarizers, since there is so much sky in the picture, with a wide variety of lighting/angles so that the sky might end up looking wrong.. |

I only use a polarizer when i think i need to, mainl to reduce reflections in glass and to deepen the sky, however i don't usually use it on any wider than about 28mm. It has been working fine for me but i would never ever leave it on all the time!!! |

Someone might disagree but I keep polarizer on only when there's use for it. Afterall extra stop or two doesn't hurt, even when it's enough light. Another thing is that extra thing infront of your glass makes more problems, so in case if there's no use for polarizer it's better not to use it. When it comes to ultra wide lenses, it will make sky on one side different color then on other. Some people like this, some people hate it. It depends on your personal taste. |

1) Sometimes the sky gets too blue (almost black) when using a polarizer, but as the previous poster noted, it's personal taste. |

If you point the camera directly at or directly away form the sun, the polarizer doesn't do anything, except block light. The effect of the filter reaches a maximum at 90o to the sun. |

Thanks for all the replies. I am aware of most of the things that was written. I carry a tripod all the time when I go hiking/backpacking. So the lose of light isn't too much of an issue. The polarizer is also acting as my dust protector when hiking. Have you ever encounter a scene where you decided that using a polarizer is doing more harm than being useful? |

It might be a stupid question but why would you use a polarizer on a digital SLR unless you want to remove reflections? The blue sky should be possible to accomplish by use of software filters (Photoshop). For lens protection use a UV filter. Another effect of polarizer filters is the lowering of the colour temperature ("colder" pictures), which not always wanted... You can get polarizer filters with build-in warming filter (81A), but you still loose 2 stops of light. |

Henrik's got it right. The only need for a polarizer on a DSLR is to reduce reflection in glass etc. and expecially in water, allowing that 2 ft trout to be seen. |

Henrik, at least for a no-good photo manipulator a polarizer does the trick better than Photoshop. I really can't just darken the sky, without affecting everything else. |

Lens cap is of limited use as a protection when hiking/backpacking, unless you are not taking a picture. The moment you take the lens cap off, the front element is naked to the elements. There lots of dust, sand, etc.. outdoors. At the end of the day, my polarizer sometimes has accumulated enough dust to warrant cleaning of the filter. Sometimes, I have to clean the filter every couple of hours due to dust. |

Henrik you can not get the clouds to have the same contrast in using PS |

I haven't tried them myself but you can get PS plugins that emulates real filters (Nik Color Efex Pro), including polarizer and UV filter, it might be worth a try? |
