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).
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...
What is this triangle indicator on my circular polarizing filter?
2018年3月3日 · Many polarizing filters have a marking like this — either a triangle or a dot or something. You'll get maximum effect if you align the camera so you're pointing in a direction roughly perpendicular to the sun in the sky and the mark is pointed at the sun. This doesn't need to be exact, but it's an easy starting point.
Is it wise to use polarizing filters with wide-angle lenses?
However, polarizing filters should be used with caution because they may adversely affect the photo. Polarizers dramatically reduce the amount of light reaching the camera's sensor—often by 2-3 f-stops (1/4 to 1/8 the amount of light).
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 ...
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.
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 the polarizer, the less light makes it through, up 90 degrees where no light makes it through.
