Further use for CPL

[Harves]

A circular polarising filter is not just for enhancing the colour of the sky, or taking the glare off water, it can also be handy for taking the glare from windows.

Example #1 is with polariser, #2 is without.

Just thought I'd share, you never know when it might come in handy.....

Great demonstration, Harves! Well worth remembering ...

[arthurking83]

LOL! good example

Also, if you're doing landscapes and the sun isn't really so affecting(cloudy or whatever!) a Polariser can still enhance colors(espcially greens and yellows) and basically render a scene more vivid and warmer too.

Yeah.... I use one most of the time outdoors, unless the light is too dull

I just love the little shopfronts, Looks good.....

Looks good Harves, great scene.

I have always been fascinated by Cross Polarising Photography, but havent ever given it a go, basically you use 2 polarisers, one on the camera, and one behind your subject (usually something plastic as the results are dramatic).

That's a remarkable difference in the window views there Harves, good tip and one I would not of thought of.

Rick, it's known as "Stress Polarization".

Certain crystals and plastics transmit light in two rays that are polarized at right angles to each other. If photographed through polarizing filters, these crystals or plastics will show interference patterns in vivid colours. When stressed, such as bending or twisting, the play of colours is quite striking.

It is sometimes used in scientific research to analyse natural stresses in certain shapes by making plastic models during the design phase.

I read the article at the provided URL and while they described how to achieve the effect, they didn’t really give any information as to what was causing the effect.

Sorry mods - double post in error - pls nuke this one.

You can use CPL's to cut out light so that you can see through water as well ....

Wow, this thread delivers!

I just learnt a few of the most useful things you would need to know in regards to using a polarizer.

Thanks guys

great example Harves. Nice shot too. I am after a 77mm cpl and I`m figuring that the hoya pro1 is the way to go for me. People say that kenko is the same but I only know the kenko is a fair bit cheaper.

Hi, wow that's interesting,I just bought a polariser and i think i will go for a walk right now and try these new tips out,Thanks.

where I've found CPL's useful :

1. As Harves mentioned : window reflections
2. Landscapes :
waterfalls (reduction of water glare from rocks),
see-through effects on water, as an additional aid to slow exposure time (not primary of course - NDs for this).
Rainbows - turning the polariser will enhance segments of the rainbow - stack a few shots with polariser in a few positions
3. Weddings : (I'll probably get caned for this lol)
- in outdoor scenes using large apertures, it certainly helps control the light on the bride's dress
- also reduction of glare brings out vibrance of colours significantly (can you remember to turn the polariser when switching from protrait to landscape though)

[stixstudios]

Great example Harves.

Thanks.

Thanks for all the tips on when to use this filter - I brought mine, had a play with shooting sky and clouds, and it hasn't come out of it's case again!

Time to pull it back out and have another play I think!

depending on needs and requirements.
A very handy piece of kit, and if not for this particular invention, I think I'd never really shoot as many images as I tend to do. The default position for my CPL's are 'on lens' ... only coming off if they have an adverse impact on the image.

[Patagonia]

nice example, did not know that application...and didin´t know they used CPL´s back in the 18th hundreds

[hark40]

And a CPL (and even a LPL) is one of the few filters whose effect can't be duplicated in Photoshop either.

[Wakaleo]

Good tip!

Gotta love the claim in the window though - 'painless dentistry'! Since when has any dentistry been painless? Even if you'd been anaesthetised for the procedure, the pain came later. These days most of the pain is felt by the hip-pocket nerve.
