  • Quickly Move A Circular Polariser Between LensesJanuary 23

    I have sausage fingers and often shoot in cold and wind. I have a 77mm circular polariser and rings that I leave on my lenses that step them up to 77mm. I find screwing and unscrewing the polariser an absolute nightmare. Sometimes it sticks. Sometime

  • Polarizing filter works only by rotating cameraJanuary 22

    I have an olympus E-PL1 mirrorless camera. I recently got a Hoya HD circular polarizer for use with a wide angle lens. Using it, I initially found that there was no varying polarizing effect as I turn the ring, irrespective of my orientation to the s

  • Circular polarizer works great at shorter focal lengths, but significantly degrades the image at longer lengths. Why?January 13

    I bought a cheap CP recently to play around with, and noticed an interesting phenomenon: Using it with my 24mm lens on full-frame, images turn out tack-sharp - there is hardly any difference in sharpness/clarity with and without the filter. However z

  • Do circular polarizer gels for creating left and right handed polarized light exist? December 21

    This question already has an answer here: Gel circular polarising filter 1 answer I am looking for a polarizer gel for our lights, but specifically one for creating left or right handed circular polarization. I can find linear gels all over the place

    Can I use a polarizing filter as a neutral density filter to create motion blur on airplane photos?October 10

    Context Looking at the answer on How do I take pictures of planes flying at an airshow? I see that many of the shots have blurry rotors. I'm currently shooting at (210mm (1.5x crop), ISO 100, 1/800, f8). A sample shot is listed below. Question From t

  • How to prevent reflections from overhead lighting?October 3

    I was taking pictures of a desk in an office with overhead lighting. The light reflected off the desk and created shiny spots on the desk so that it wasn't uniform. Is there a way to prevent this? Would a polarizer work? --------------Solutions------

  • What are the Hoya circular polarizer types?August 31

    I have a Canon 18-55mm lens. I want to buy a new polarizer for it. The diameter of my lens is 58mm. I want to go for Hoya. But there are 5 or 6 different circular polarizers of Hoya for 58mm diameter. I'm confused about which one should I go for. Can

  • In what type of conditions do I use a polarizer on a 300mm lens?July 13

    I found the questions relating to polarizers, but haven't found any info on a 300mm zoom lens with a polarizer. Is this because it is not suggested to be used on 300mm zoom lenses? I use this lens to do close-ups indoors and outdoors with a tripod. I

  • How can I use a polarizing filter with my Canon Powershot G15?June 22

    I am about to be in Utah for about 3 months for work, and rather than lugging my full DSLR kit I am only going to take my Canon G15. However with the landscapes and skies I expect to see, I know that I would want to use my (circular) polarizing filte

  • Gel circular polarising filterJune 21

    I am contemplating buying a lens that only takes rear gel filters. Is it possible to buy a circular polarising filter in gel format? If so, who can supply them (preferably UK based)? --------------Solutions------------- You can get sheets of polarizi

  • Why do phase-detection focusing sensors not like linearly polarized light?

    Why do phase-detection focusing sensors not like linearly polarized light?May 22

    I learned that polarizers did not work with autofocus and we had to get new "CPL" filters, 27 years ago. I even understand how they work and the nature of the light produced, which was a lot more effort in those days. But I never found out why p

  • Polarizing filter causing soft, hazy shots?

    Polarizing filter causing soft, hazy shots?May 4

    I'm having a problem with a polarizing filter that's I've used for years. I have a Nikon D7000 w/18-200mm lens. I keep a UV filter on the lens, and on occasion I add a circular polarizer, which just recently began giving me images with exactly the op

  • Recognize dry areas by separating diffuse and specular reflections February 26

    This is a machine vision/imaging sort of a problem where we wish to detect dry areas on mostly wet surface. In order to reliably do that we'd like to optimize the imaging side of it. At the moment we're going for making use of the specular reflection

  • Add an orientation mark to a polarizing filter's rotating ringFebruary 21

    I love the effect a polarizing filter can have when used appropriately; less so the need to rotate the filter around to work out its current orientation. I like the idea of adding a clearly visible notch or dot to the top and bottom of the rotating r

  • While stacking filters, can polarizing filter be placed behind ND filters?

    While stacking filters, can polarizing filter be placed behind ND filters?January 27

    I have a ND filter (10-stop, 100mmX100mm square size) with a filter holder. The filter holder (similar to LEE or Formatt-Hitech holders) connects to the camera with a screw-in adapter (77mm and 82mm). This particular adapter has a rotating element wh

  • What do I need to know about using a polarizing filter at night?December 14
