with pola on, cause in any case you loose about 2 exposure steps...
so is polar=ND filters?
(i know they are DIFFERENT.but can a polar act LIKE a ND considering 2 stops loss?)

yes, you got that right, at certain angles (for example with the sun in your back, or straight into the sun) the pola acts like a ND.so is polar=ND filters?

ok because its you, your thumb and index finger actually form a 90 degree angle when stretched out. so point the index to the sun, and look where you thumb is pointing too.... and if you are observant you would say now that the thumb can point in different direction depending on how you twist your arm or wrist... correct, the 90deg apply to a circle or plane 90deg to the sun's direction.... got it or do you need a practical session?you know me.i want the full details.i dun wan to learn 1/2 1/2 bucket of water.:bsmilie:
so HOW do i measure 90degrees?
:dunno:
actually you got to be careful even with wide angle lenses that cover more than 90deg....Also you cannot use a Pola in a panorama sequence. You can with an ND.
Are you sure?hav commercial plugin 4 that.
Can explain more?actually you got to be careful even with wide angle lenses that cover more than 90deg....
as mentioned above, the polarization effect is biggest when pointing the camera at 90deg to the sun. So lets assume the following example: you have a lense that covers 180deg (a fisheye), you point the camera/lense at 90deg to the sun, then the edges of the opening angle covered by the lense will be in direction of the sun and directly away from it respectively. So the centre part of you pic will have max. polarization effect and the edges will have none at all... so if you have a blue sky then it would be dark blue in the centre and light blue at the fringes of the photo.... some may like it some not....Can explain more?

Well, then.... pray tell... how do you replicate the effects of a CP-L when you're shooting at surfaces of water and trying to capture the fishes just under the surface without the CP-L and using CS... :think:
I think you have to use photoshop and the use the plugin (pictures of fish in your case) and then superimpose under the existing picture.

:dunno:
Do show me a photo when you have done so... frankly I dun think it's possible to replicate the same thing at ALL.

For Nikon CPLII will lose 1.5 stops exactly...with pola on, cause in any case you loose about 2 exposure steps...
Usually the polarizer come with small manual that will tell you the lose light number in stops. Does it come with Nikon CPLII? If yes, how much Nikon put there?For Nikon CPLII will lose 1.5 stops exactly...
If you ask me how do i got this value???
i say is from my camera.
