Whereas a CPL actually polarises, meaning only allow light in certain planes to pass through. I prefer a CPL because rotating before taking a picture produces interesting effects. xc

Here's a practical example of how it's used (Cokin grad grey ND8): Without the filter, there won't be the blue gradient in the sky. In fact, the sky would likely be blown out white/grey.
