Hi Guys.

I recently caught the bug (ok maybe 9 months too late) for getting a black lens (10 stops) and exploring it since I have seen a few gr8 images lately using the ND400 or equivalent from B +W or Lee from people like Kane and JP on Flickr and others here so I ordered the B + W version and then went looking for tips on how to use it.

I came across this excellent, wonderfully detailed explanation with fantastic tips which you could apply to use of any ND or GND filter by an Aussie no less. It is well worth a look over even if you have been playing with NDs for ages.. the images themselves are inspiring. Here is the link.
