Hi everybody,


I recently purchaced my first polarizer, a B+W 77mm MRC Slim Circular Polarizer Filter. First I wanted to verify that I am using it correctly. To acheive its maximum effect, if the sun was directly above me I should set the notch in the filter to the sides (3 o'clock or 9 o'clock), if it was to my sides I should set it to the top or bottom (12 o'clock or 6 o'clock), is that right?



Next, my friend accidentally bumped my lens /w her hand and now I have two big finger prints right on the front of the filter. I'm wondering what is the best way to clean those off? Do I need some special liquid to clean it off? I have a LensPen here, I don't know if I should use that or not.


Thanks a lot (Btw, this is my first post, excited to get involved in the community!)


Best,


Nick
