Pros and cons of circular polarizer filter vs a linear one
The polarizing filter works by selectively allowing light waves that vibrate in only one direction to pass. The photographer is required to fine tune the effect of the filter by rotating it for best effect. The net effect is the polarizing filter darkens clear skies causing white clouds to stand out.
What do I need to know about using a polarizing filter at night?
2014年12月14日 · To be honest, the advantages of using a polarizing filter at night are limited. The vast majority of people who purchase a polarizing filter are using it to darken the sky for landscape photographs. Others may also use it to remove reflections in glass or water (or general glare from photographs).
Is it wise to use polarizing filters with wide-angle lenses?
That makes for pretty strong polarizing effect, and as the lens is a wide angle (18 mm on a crop sensor body) it means the angle of light is 90 degrees only in the middle of the view. The angle of sunlight is far from the optimal 90 degrees on the sides of …
How can I fix a sticky polarizing filter? - Photography Stack Exchange
2017年4月25日 · I took a gamble and bought a used B+W Circular Polarizer off eBay. The filter looks great but the adjusting ring is a little bit sticky. Is there some way to lubricate this?
How do I find the right size of filters for a lens?
2011年4月13日 · 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 62mm, 67mm, 72mm, 77mm...
Is it possible to use a polarizer and a ND filter at the same time?
2011年6月30日 · The front element of the 18-55 rotates when focusing, which makes using polarizing filters a bit irksome. But other than that, yes, it should work, although using multiple filters on a lens is something that should be avoided as far as possible on general principles because of the added risk of flare, internal reflections, vignetting and other ...
Why do polarizers cause vignetting? - Photography Stack Exchange
2017年8月16日 · The polarizing filter reduces reflections from glass depending on the angle which is 57° for glass and 53° for water. When it comes to blue sky, the angle of maximum effect is 90°. Since the wide-angle lens envelopes a super wide view, much of the expanse of a mundane sky will display different levels of strength as to the effect of ...
Is it possible to safely disassemble a polarizing filter?
2013年7月2日 · I just purchased an Hoya PL-CIR filter off craiglists (I'm starting photography and it was cheap) and it looks like there is some dust/dirt between the two lenses. Is there a way to safely disasse...
Can the effects of a polarizer be replicated in post-processing?
Any easy solution using these Softwares ? or is it better to buy a polarizing filter itself ! I use Canon EOS 1000D , and mostly use 50mm 1.8 and 70-300sigma lens. photo-editing
Can I stack ND Filter and Polarizer together?
2018年4月30日 · The ND filters do not polarize the light, unless they are also polarizing ND filters (there are a few of those, but they are not common). * Caveat: I'm assuming you're not using variable ND filters. Variable NDs achieve their affect by stacking two polarizers in the same filter, that can rotate independently of each other.
