    This ist a small tut on NPR I found time ago in some UK web:

    Open any photo or rendering into Photoshop.

    First of all, duplicate the current Background layer by simply dragging it down to the Create New

    Layer icon, while holding down the ALT key. You can now rename this layer to 'Find Edges'.

    With the Find Edges layer active, run the FIND EDGES filters by selecting it from the FILTER...

    STYLIZE menu.

    Bring up Levels Command Dialogue Box by pressing CTRL+L together. In the INPUT values, enter

    '0' in the far left box, and enter a number between '200-208' in the far right box. What this does is

    bring more of the white out on this level, removing some unwanted picture data.

    Now remove all colour from the layer by either pressing CTRL+ALT+U or by selecting the IMAGE...

    ADJUST... DESATURATE command.

    Once again, duplicate the original Background Layer. In the Layers Palette, move the duplicate so it

    sits on top of the Original Background layer. Rename this layer to 'Paint Brush'.

    With the Paint Brush layer active run the Median filter by selecting Filter ' NOISE ' MEDIAN. When the

    dialogue box appears, enter a value of 2 and click on OK.

    What this has done is 'soften' the image, reducing the harshness of the brickwork.

    Bring up the Levels Command box once more (CTRL+L) and enter a value of '21' in the first Input

    Range field (far left), and enter a value of '255' in the last box of the Input Range field (far right). Click

    OK to apply the new settings.

    Ok, so now we are at the halfway stage. You should have on your screen, an image that is looking a

    little darker and slightly blurred. Don't worry that you can't see the layers beneath - that is still to

    come.

    Our next stage is to add the actual paint effect:

    With the Paint Brush layer still active, run the Fresco filter via Filter 'Artistic ' Fresco. When the

    dialogue box appears, enter these values: Brush Size = 10, Brush Detail = 2, Texture = 1. Click OK to

    apply the new settings.

    Once the Fresco filter has been applied, change the Blend Mode of the Paint Brush Layer to Soft

    Light. Simply do this by clicking on the Black arrow that is just under the word 'Layer' on the Layers

    Palette. Select Soft Light from the sub menu.

    Click on the 'Find Edges' layer in the Layer Palette to activate it. Change its Blend Mode to Soft Light

    Click on and drag the 'Paint Brush' layer on the Create New Layer icon in the Layers Palette to

    duplicate it.

    Remove all colour from the duplicate layer by running the Desaturate command from the Image '

    Adjust menu, or by pressing the key combination Shift+CTRL+U.

    Run the Find Edges filter from the Filter ' Stylize menu.

    When the filter has been applied, change the Opacity of this layer to somewhere around 63%.

    Final part now. Bring up the Curves dialogue box. When it appears, alter the diagonal line until it

    looks something similar to the one provided here:

    Optional: You don't have to stop there. Why not add a canvas to the painting to give it a little more

    texture? Flatten the painting image, and then rename the Background layer to Painting. Change the

    foreground colour to #EAC578, and then run the Texturizer command (Filter menu, Texture...

    Texturizer). Change the opacity of the layer to about 63% and the blend mode to Soft Light.

    Add more effect by running a program such as Extensis Photoframes to add a border around your

    image, or create one yourself.

              Thanks for this tut. I'll find it very useful.

              You may also want to check out this Photoshop action. With a little tweaking, I have had good success with it.

              http://www.deathfall.com/download/mels/EDGE.atn

              It was attached to a tutorial for cartoon edges using RAT (Renderman Artist Tools) written by Stefano Tabacco. The action is an independent file, RAT is not needed for good results. Credit goes to Stefano for this action.

              I might try to find time to turn the tut you posted into an action for PS in the meantime.
