how do I use Digital Optice adj. polorizing filter?

[GTO_Dave]

Hi all,

I just got a Digital Optics 3 pc kit form E-bay for $10. the outer ring on the polorizing filter is moveable. My friend says its an adjustable filter. But there are no marks of any kind to show that is is 90 degrees or whatever. Are all polorizing filters adjustable? IF the rng spins, is mine adjustable? If so, how do I use it? thank you all for your help

Well, mine is. There's usually a white line on the adjustable ring that acts as a guide.

As for the degree of polarizing, I depend on the LCD to judge... If you shoot on, say sunlight reflected off a car's windscreen, you can see the polarizing effect by adjusting the ring.

COLL! thank you so much. I was having so much trouble. No matter what I did I couldnt see a difference. But when I tried the sunlight reflection I could actually see the diff. thanks again
