- polarizer - How can I reduce reflections in a glass corner . . .
About circular polarization: Most cameras will work just fine with a standard polarizing screen In modern times, especially with digital cameras, the internal mechanisms can be defeated if a polarizing filter is mounted We mount a circular polarizing filter This is two filters sandwiched together The first is an ordinary polarizing filter
- Why do polarizers cause vignetting? - Photography Stack Exchange
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?
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
- In which situations should I use my circular polarizing filter?
A polarizing filter, particularly circular polarizers, are a great tool to balance out and enhance a scene They do reduce the rate at which light flows into your lens, so a slight exposure adjustment is usually necessary to compensate They are generally worth it, if you have one, and can help improve your shots
- Why do polarising filters only work in one direction?
Because mounting a polarizing filter is often desirable, we need one that will not do mischief The polarizing filter we use is actually two filters sandwiched together The front facing filter is an ordinary polarizing linear screen This one does the job It mitigates reflections, cuts haze, and increases saturation
- filters - Why dont circular polarizers reduce light transmission by . . .
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 circular polarities ("right" or "left) Yet "standard" circular polarizing filters cut light transmission by 1 5-2 5 stops
- filters - Can a circular polarizing lens (CPL) be rotated to end up . . .
From what I've read and watched, a CPL can cut reflections glare and increase saturation (mainly the blues) Also, these effects can be adjusted by simply rotating the fil
- How do I choose a polarizer? - Photography Stack Exchange
As Guffa notes, you'll want a circular polarizing filter (abbreviated CPL) as linear polarizers are incompatible with most autofocus systems Other good brands include B W and Hoya Be sure to get a multi-coated filter, to cut down on reflections For the Marumis, this is the DHG or Super DHG lines
