It is not DOF that is desired to be controlled but shutter speed. If you want the sea or water to blur then you need 1/4 or 1/8 second at ISO 100/200 at normal f8 aperture for best sharpness from lens. You need to use ND to get these shutter speeds. I find I need ND of 4 stops. This would mean changing to ISO6/12 (not possible on current cameras). Many variable NDs are two polarisers working in opposition but these give colour casts (brown/green) also polarisers ate not good when used on wide angle lenses. Many landscape photographers use flat ND filters but these are expensive for a superwide angle 14mm as you need a 150x150 or 150x175mm. Going later in the day may be impractical or the light angle changes so the photo does not work.

Many people make the mistake of photographing them in full sun when the contrast range is to high to retain detail in the water. Even when it's meant to be blurred it shouldn't be burnt out or even spectacular white. 😉

Yep, I know the problem. I managed to just about get it right here but it is not perfect.  Shooting upwards also means that even with HDR the dynamic range is huge. This is not HDR and I didnt have a tripod with me that day.

This is a fail. I need to repeat this image as I was there at midday on a sunny day. I will return on a cloudy day in September. This is HDR and still it is not right.

I like that second one , as I appreciate when some movement is shown, and looking forward to you returning there to " do it over " just to see what you have in mind...is this in Cornwall ?

I suppose this is where tastes differ. I too prefer the second image. I would have just masked the area in shade, adjusted the white balance to get rid of the deep shade blue cast and lightened the mid tones like this....

The first shot, to me, exhibits the sort of white out that I don't like to see. It loses definition by virtue of over exposure rather than movement. Areas I've greyed out.  Incidentally....you've left a black masking outline around the sunlit rocks. 😉
