The circular polarizer remove reflections in water.
I used a 55mm Vinson Polarizer a well known brand.
It seems Linear behaves differently to circular.

Adjusted for Maximum Effect

My bird bath



Adjusted for Minimum effect............

Strange I have both an expensive (for me) CP and a much cheaper Linear ...both are Hoyas and I prefer the linear but seldom am I trying to remove reflections... if we get some warm weather I will give them a test.

Looks like it works well with water John. Will it do the same for glass? Jim

polarizers will remove or reduce reflections from almost any surface except metal. water and glass will become more transparent, the 'shine' on plant leaves will disappear, etc. all this in addition to deepening tbe blue of the sky, and enhancing contrast and saturation. you can see why a polarizing filter is such an important part of any photographer's kit... :G

Min Polariser effect (Circular)

Backlit no polarising

John, they both have the same effect and purpose, both will reduce reflections and glare as well as deepening the blue of the sky and adding saturation to colors. Circular polarizer were only created to circumvent some auto exposure issues some cameras had with the linear filter, but they are supposed to do the same. The FZ's work well with both. I only gota cheap linear one from Raynox. I do not know how dramatic of a change a really expensive polarizer makes.

By the way, John, isn't the first picture with the polarizer on and the second one off?

Circular one's are less effective ! but mandatory for SLR or similar cameras with optical viewfinders, not our case, keep with linear, for FZ.... and they are cheaper also, but go for High-end brands like B+W, Heliopanor Rodenstock, I have a B+W Linear oneMRC F-Pro line, superb construction and superior results, believe me, I've tested many.
