There's a lot of different things you can do with one grey-scale layer set with the layer mode to [Divide] over another grey-scale layer, but here is just one neat thing you can do. After working with the two layers you can then create a new layer from visible and then apply a gradient to it using [Colors] + [Map] [Gradient Map].


First make a selection on screen.


Then go to [Select] [Border]. In the Border Selection dialog box choose a thickness of 50 or whatever and put a check box in the Feather field and hit OK.


Now simply fill the selection feather with the Foreground color of black.


Create a new layer above that layer and fill it with black. Also change the layer mode to [Divide]. And make sure that you unselected or select all of the canvas area.


Now simply draw with the airbrush tool using a foreground color of white above the image that the selection feather made on the layer below. You will notice that the more you airbrush in one spot the thicker the bevel gets from the layer below. Create thick and thin spots by airbrushing more in one spot. You can also hit the X key to toggle between the white and black foreground color to draw and undo areas.


In this last step you must first create a new layer. So click the [Layer] menu and hit [New From Visible]. Now click the gradients tool from the toolbox and choose a gradient that you would like to use to replace the grey-scale canvas gradient with. With this new layer active click [Colors] [Map] and then [Gradeint Map]. And now your canvas gradient should now be replaced with the gradient you had selected earlier.

And thats it, enjoy...

PegLeg I made a PDF of your excellent tutorial and added it here. I also included the two images you made later - O

If you start with an eighty percent black screen and then create a 100 percent black [Divide] layer above it you can then draw with the white airbrush and then use the smudge tool which will work almost just like an iWarp filter but you get to use the whole canvas. This is a great way to make rounded gradient shapes.

The image below was done in this way before creating a new layer from visible and using [Color] [Auto] [Stretch Contrast] before a gradient was applied.



As far as my new avatar I wanted to do something like that Mr. Bean. I know it looks kind of crazy but I'm actually a down to earth guy who doesn't mind making a spectacle of himself.

How about a smooth neon path with a straight gradient.

Here's an image I made using this technique. A lot of techniques actually. I could post the xcf file if anybody wants to see it.

the horse picture is beautiful!

That is very cool PegLeg44. Very nice job.

PegLeg44: This is really interesting and educational. After reading your post, I invested a good bit of time playing around with two grey scale layers with the top set to divide. You are right that there are a lot of things that can be done.

I would be very interested in seeing your xcf of the horse if you decide to post it.

Ya here it is. I use layer groups a lot. Roundness kind of happens naturally doing it like this.

Very nice PegLeg. I added a PDF document of the tutorial and put it in your first post. I love the effect.
