I never thought I would say this, but I can now see why one may have use for a ND Grad filter!

The white sea here is not white because it was choppy, in fact quite the reverse, but because it is over exposed. With an ND Grad I could have exposed the rocks correctly and also the sea, retaining detail and reducing the glare. I suppose I could have used a circular polariser as well/instead because that is good for -1EV or there abouts.

So new shopping list! I will go for Cokin P-System filters owing to the price/performance issue I need the following:-

2 adapter rings, one 52mm for the nifty and one 58mm for both the telephoto and the kit 18-55mm
1 P system Filter holder
1 ND Grad 4 - good for a couple of stops of exposure.

The trouble with using this arrangement is that the slower shutter speed will increase the water blur, which in turn will prevent one from seeing the spiky effect as the water crashes (!) over the rocks.

Another suggestion has been that I take an equivalent picture but in landscape orientation. next time I get over to Kimmeridge I will try that as well - after all I have a tripod and I am not really afraid to use it!
