Can I ask, what's the use of a ND filter? when I have a circular polariser. I know the ND filter is suppose to stop down the exposure so that u get silkier water etc. but won't the polariser do the same?

The main purpose of using neutral density (i.e., ND) filters is to reduce the amount of light that can pass through the lens. As a result, if a shutter speed is kept the same, after adding a neutral density filter, a larger aperture must be used to obtain the same exposure. Similarly, if an aperture is kept the same, after adding a neutral density filter, a slower shutter speed must be used to obtain the same exposure.
The 'silky water' effect actually is a motion blur of the water, when ND filter is needed, it means you can't get a shutter speed long enough.ConnorMcLeod said:Let's say I wanna shoot a waterfall with the 'silky water' effect. I want everything sharp so DOF is max, hence I can live with small aperture.
My question is, would ND filter vs use a long shutter time + tiny aperture produce the same effect in this case?
