How do I create this effect?

[Bernhard S.]

Hi guys.

I've been staring at this image for ages, trying to figure out how to do
this.

Basically, its a splotchy streak of pain. But, where the paint is present, a
pattern can also be seen.

http://www.helikopterdesign.com/wp-content/themes/default/images/backgroundtop.png

The image is a background png from the beautifully designed page at
http://www.helikopterdesign.com.

I'd like to know how how to make the pattern visible only where the
brush-created pixels are.

Any advice on this is appreciated.

Thanks.

Thank you.
I'll play around and see what results I can get.

Cheers.

pull out the camera.
the "paint"ed bit looks like it got
a bit of flash towards the left
(could be intentional).
but i agree with the basic outline mentioned.
cheers.

I've been playing with this technique. I'm getting quiet excited about what I
can achieve with it.

I'm also wondering - is there a way to save the selections?
Usually I save my selections by saving them to a path. Of course, I recognise
that paths are solid, so they won't save the gradations in alpha values.

So, is there a way to save my selections, maintaining the different alpha
values in them?

Thanks.

Select->Save to Channel.

Then to reload, right-click the saved channel and do 'channel to selection'.
