I explained my examples are not good choice of ND filter use. ND grad and ND hard have similar use, I use both. Also look Big Stopper link for ND hard before and after example. Hard ND filters also increase capture of Dynamic Range of whole image, not just for slowing shutter.
Hard, in addition to soft, is a type of ND grad filter. Its refers to the transition of the ND portion, be it a subtle transition, useful for most scenes, or a hard edge, which is very pronounced, but that works well for things like seascapes where the horizon line is distinct and flat across the frame.
It sounds like your calling a basic ND filter, not a ND grad filter, hard ?
It furthermore sounds like your suggesting that using a ND filter, not a ND grad filter, will increase the dynamic range ?
