Circular Polarizer - Orientation


When will a circular polarizer have the most effect on the blues in the sky? I've not quite made the connection when out shooting; sometimes the results are very pronounced, with extreme darkening of the blue as I rotate the ring, and other times, I can see absolutely no change when rotating the ring completely through 360 degrees... I recall reading it has to do with the angle of the camera/line-of-sight to the subject, and the location of the sun. Thanks!

  When you are standing facing your subject, if YOUR shadow is to your right or left, the polarizer will work. If your shadow is in front or behind you, it will work very minimally or not at all.

  For the biggest effect, you need to be perpendicular to the sun.

  Thanks, guys! (I believe you're both saying the same sort of thing!) Will definitely try it out on the next sunny clear day...

A handy polarizer info I used when I got my first polarizer.

  Wide-angle lenses are not recommended for polarizing skies, as a part of the sky will be decidely darker - more saturated - than the rest, and you'll end up with a 'patchy' sky.

  yep, 90 degrees to the sun

works best generally around midday when the sun is directly above, or when the sun has just risen or set, and then shoot 90deg from where it is.

  Chris -

One other thing to remember about the polarizer When shooting in the mountains the higher you go the less polarization you need to use. A little goes a long way.

  Also when shooting panoramas don't use a polarizer or the sky will come out decidedly uneven, as I discovered.

  Going with the panoramic issue,

i think sometimes the uneven effect can be quite effective, especially if its subtle.
Depending on lighting (time of day) and whats in the sky, ie clouds, you can get some really nice tones through the horizon, rather than just a simple saturated blue/white.

My opinion anywayz, who says perfect is perfect :)

  Thanks for asking, Chris and thank you all for responding. I will also keep your suggestions in mind when next time I go out shooting with a polarizer.

UB.
