What a CPL can do

[ecobo]

Hi!
Do you like polarizing filters? I do. I like the effect they can produce.
This is a shot with a circular polarizing filter (CPL) I've shot the last weekend. There's no PS-ing except the usual - the photo was shot in RAW format and it was processed and saved as JPG in PS CS.

How did u get the dark to light gradient so even across the sky? with my CPL, it's more like a circle distribution, where in the middle of the sky is dark and gradually outwards, it gets ligther.

The most important for producing a strong effect is the position of the sun. It must be positioned 90 degrees from the axis of the filter.
About the type of the gradient - I don't know. It may be a matter of the production process. I use a cheap SUNPACK filter.

I LOVE my Polarizer. It has made some medochre scenes absouluely breathtaking. I use it almost continuously for outdoor shots. I will start paying attention to my angle to the sun more and see what I can do with it more. Thanks for the tip!

That's absolutely right.
And even without a CPL filter, it is at 90 degrees from the axes of the sun that you'll get the deepest blue sky.

The axis of the filter is a straight line, perpendicular of the plane of the filter's glass. Or (let's say it easier) think of the axis as a line that enters your lens and passes through the centers of all the lenses of your lens. (wow, it's hard to explain :roll: )
So, the strongest effect of a CPL is obtained when the sun is positioned 90 degrees from the filter's axis. Got it?

got it ecobo
thanks :wink:

Thank you for spelling that out as I was confused too. Good point to know. I use the CPL (Corporal?) all the time but really don't know what I'm doing with it.

You mean to have the sun on the right or left relative to you.

[yikes]

Im not following either, can anyone post a diagram?

No matter. Just 90 degrees (or less).

if you look at it lke a clock, your subject is at 12 o'clock, the sun needs to be at 3 or 9 o'clock.

Point your thumb at the sun and rotate your pointing finger in an arc while keeping your thumb "on" the sun. The arc will be approxamately 90 degrees. Also looking through the viewfinder while turning the Circular Polarizer wll show the darkening and lightening effect
