Thanks guys, v. much appreciated.
Alas, tis not all. I have indeed understood about defining, but as to the state the image needs to be in before you define it, I am still unsure. I'm not talking solid shapes here, I mean where you're playing around with opacities and contrast. Here is a link to
the image I'm working from - (

and what I've done/looking to do -

Of the second image, in the bottom left and top right, the one's in blue, are prints of the brushes I've come up with. Same define, just different levels of contrast. The one's in grayscale, top left and bottom right, are the one's I'm looking to make a brush similar to. And If you've seen, as I mentioned before, Biorust's "Ancient Maps", then it's that I would like to make a similar brush to.
Once more I put a question forth. What state does an image need to be in, and how would you achieve such a state?
Many thanks to anybody who provides an answer.
