Hello all,
I have brought a second hand Cokin screw on polarizing filter, Once screwed to the lens the glass will rotate, as I've never used one before am I surposed to rotate the glass to get the affect ?
I have tried it quickly it takes a stop of light away but does not seem to make a lot of difference if rotated !
