I know what an ND filter does. I know what a polarizer does. I also know what two polarizers stacked together and rotated properly do. So the question: why should I use an ND filter to achieve a ...

I have the Tiffen 0.9 ND filter which gives me approximately 3f stops reduction. I like to really slow things down and although it's sufficient in low light it just won't do in daylight. Should I ...
