No blur was added, it was achieved by using a shutter speed of 2 seconds, longer on others. I did have a polariser with me that day, but didnt think to use it tbh. Thinking about it now, it would have helped quite a bit! I'm only a newcomer to Digital Photography, and would like an ND grad set at some point.
Thanks for the other pointers, I just feel they dont have that umpff to them...
Maybe its just because it was overcast, and not a great time of year...I will re-visit in a month or so, and see if my skills improve by then...and remember to take my mat!
