Hi everyone! I feel like the "lost son" who arrives only when something is needed. But it's nice that I know I will be helped!!!

Well at last I've got a circular polarizer for my DX7440. Like with most compact cameras the polarizer is screwed in the lens adaptor and that in the camera's body. So it's time cosuming and not so wise to screw it on and off all the time.

My question is: does itallways give onlypositive effect when shooting outdoors, or are there circumstances, situations when it should be better screwed off.

I used it all the time in my first try, and I noticed no problems, but may be that's not the right way allways? It reduces the exposure by as much as -2 f/stops, but that's not the problem when shooting in daytime.

I will be gratefull for any suggestions, advices!!!:?

Thanks!

Maris.

Welcome back Lost Son!!! LOL I keep one on alsmost all the time outside! Sometimes when shooting into a shadowy area I remove it but that's not that often! It will always work best and give the most benifit when the light source is 90 degrees to the subject you are shooting!

Thanks for the nice picture. I couldn't paint so beautifull.:-)

Should Iadjust the degree of the polarizer regarding what I see in the LCD display, or regarding the degree of the light source to the object? I haveturned the polarizerby 90 degrees on the lens.

When you turn the polorizer 90 degrees from the most polorization, you have removed all the polorization! Since most polorizers have a tint you will still have a change in F-stop from a normal lens because the tint will darken the light entering the camera! I mark my polorizer with a white fingernail polish at the point where I get the most polorizing effect! Then a 90 degree turn will drop the effect quite easily! That way there is no guess work as to where the most effect will occur!

Happily, I haven't mistaken. May be I described what I did not clear enough. At first I did test shooting at my car's windscreen and noticed the maximum polarizing effect. And it was "what I called at turning the polarizer marks (there are such small) from vertical position to horizontal, that is by 90 degrees.

I will post 2 pictures as well.

First Nissan unpolarized.
