Re: My circular polarizing filter doesn't seem to have a very wide change spectrum?

It occurred to me the other day that if the 90 degree angle rule to the sun is always applied, one can only get good blue sky effect faceing North or South....youll never be 90 degrees to the sun facing East or West?

 

I find some of the best use for polarizing filter for seeing though windows or removing glare from surface water.....

 

 


You can get dramatically blue skies during the golden hours, too.

I followed the method you have posted and it did not work out for me and I am a user of canon error b200 and I purchased it 2 months ago.

Do circular polarizing filters come in various strenghts or ranges of change?  ARe all C-polarizing filters the same?  Yes, I know how to use them. I know the 90degree angle to the sun and all that ...I feel that I should be able to rotate the filter and see through the lens excactly what the change will be...frankly I find it very difficult to see the amount of change in the blue of the sky using the filter that I have....shouldn't you be able to rotate the filter and observe the change gradations?  Shouldn't they be obvious as in a ND filter?  Should I ask for a "stronger" polarizing filter?

I look through the lens and turn it  how much I am affecting the "blueness of those patches".  I thought you were supposed to be able to see those changes as you rotate the lens...but I have not found much success noting those changes using the LD display or through the lens

Remember that when you're looking through the lens, the lens is at full aperture, which is not necessarily the aperture at which the image will be captured. You might get more accurate results by using the preview button.
