Richard thanks for the explanation. I got the flood filter just last week, but I need to play with it some more before I can make it do what I want lol. Thanks also to all those that posted an explanation of their P/W and everyone that has had a play. As I have already said. Some of this kind of post work isnt my strong point, so I have found this quite inspirational (oh no watch out gallery lol)

The Truth is Out There
