Proper way to use a circular polarizer

This is probably a dumb question, but it will be dumber if I don't ask. I just got a Hoya Digital Pro1 Circular Polarizer. It's got an outer rotating part (where the filter is mounted), with a little arrow in one spot. I see that the effect changes as I rotate the filter. The "indicator" is not always up, so I end up rotating it slowly until I find the position with the most contrast or least glare. Makes sense, kind of like polarized sunglasses. However, it's a major pain. Of course, I can't adjust the filter with the hood on. So the hood comes off. Second, it just takes time.

Am I using it wrong? Is there a simple technique to make this a bit easier? Thanks!

Nope, you're doing it right. It is a pain with a hood, but that's about the only way to do it - look through the viewfinder while rotating the ring to get the effect that you want.

Thanks. Did a bit more searching and found this thread... https://photography-on-the.net …+use+a+circular​+polarizer

tamron now makes a lens hood with a thumb screw that adjust the polarizer via the notches on the side

A polarizer is helpful when shooting cars right?

Possibly. It will reduce the glare on the paint and on the glass, increase color saturation, but reduce the overall light reaching the lens (so not so good for indoor shooting). It won't reduce flare/glare on metallic objects.

Okay, thanks.
