cheers Chris no didn't use the polariser just the lens for these and yep have thought about ND filter and blurred smooth sea especially at sunset thinking of staying down there overnight one weekend to do it, These are using canons landscape setting and manual mode, all I have really done to these is sharpened slightly and re-sized they came out like this on camera, was nearly midday and the sun for once was slightly behind but above me couldn't have timed it better really. The area really is something special want to try from various vantage points on next visit its only about 30 mins away from house so pretty close too,.
cheers Tim
