  1. Is it wise to use polarizing filters with wide-angle lenses?

    18 I've been looking into whether to use a regular UV or polarizing filter for a 16mm wide-angle lens and have found that a large number of people believe that you should never use a …

  2. Are polarizers effective against reflections from glass?

    Dec 14, 2020 · CPL filters do not differ in their photographic properties from linear polarisers; they are merely friendlier to metering and autofocus. But in essence they are just linear polarisers …

  3. What is the difference between using an ND filter versus 2 …

    A polarizing filter only lets through light with a certain "orientation" and proportionally filters out light rays with different orientations. The further the orientation is away from the orientation of …

  4. polarizer - How can I reduce reflections in a glass corner ...

    Feb 22, 2017 · I understand from questions such as this and this that circular polarizing filters can reduce a camera's view of light reflected on glass. Would a circular polarizing filter be …

  5. filters - Why don't circular polarizers reduce light transmission by ...

    8 I assume that an ideal circular polarizing filter should cut light transmission by exactly half – i.e., 1 stop – because every photon has (on average, with respect to a filter) either one of two …

  6. What is the difference between a linear and a circular polarizer?

    A polarizer works in the way that it will let through only the light that is polarized in the same direction as the filter is currently turned. It is true that many AF systems have problems with …

  7. What do I need to know about using a polarizing filter at night?

    Dec 14, 2014 · I am into night photography, and am looking at buying a polarizing filter. What particular advantages and challenges are there to using a polarizing filter at night? reflections …

  8. Is there any filter opposite to Polarizing filter, to emphasize ...

    Polarizing filters are mainly used to reduce glare on water or similar surfaces. My question is, are there any filters that do the opposite job? ie that allow the camera to capture more glare or …

  9. How do I find the right size of filters for a lens?

    Apr 13, 2011 · 26 I was looking to get a circular polarizing filter and an UV filter for my Canon 550D, 18-135mm lens. When I checked online I found these filters came in different sizes, like …

  10. polarizer - Polarizing filter - degree of polarization vs polarizing ...

    Oct 16, 2020 · The bulk of polarizing filters these days for photographic purposes are so-called "circular polarising filters", in brief CPL. They consist essentially of a proper linear polariser …
