<p>Bill and William - thank you both for the links, they were very helpful.<br>
William, <br />I see where you are going with this, it will be hard to know which effects I want to achieve, as I haven't photographed waterfalls successfully. <br>
I went to Plitvice Lakes back in 2012 without the ND filter, and right away I knew that I needed one. <br>
I am really considering the idea of a variable filter. <br>
If I only get one filter, are you recommending a good starting point is ND64? </p>
