Basically you use layers and your masks. You would for example have two layers, one with the green design, and one with the yellow design. Then switch on your quickmask (bottom left corner there is a box that turns the image redish), and using your favorite grunge brush and the brush tool, start painting the spots you want to delete on the top layer. After that click on the quickmask again, which will cause the area you painted to become selected - yes in the shape of your grunge. Now just delete that area from your top layer, and the bottom layer will show through. Alpha transparency also takes effect here so you end up with some areas that are kind of green and kind of yellow.

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.

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.

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

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?

Select->Save to Channel.

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