This Tutorial should be still revised, some illustrations are missed and some tips may be added
Anyway is taking too long to update and since many complains that was anymore available i move temporary back in the Tutorial forum.
But i hope to replace soon with a newer version

is released under CC you may want download the original size ( http://www.flickr.com/photos/vonbergend ... 488065788/ )for use in this tutorial
here is a possible result

(others sizes http://www.flickr.com/photos/photocomix ... 729454484/ )
Is also possible boost the effect as here with a simple additional step

(more sizes on http://www.flickr.com/photos/photocomix ... 728628849/ )
HOW TO
1 duplicate the layer
2
Filters/artistic/photocopy..

the setting i used are visible in the screenshoot but give more attention on the preview:
different images may need some change in the filter settings while result should look in the filter preview similar this image.

3
Now start Greycstoration plugin ( Filters/enhance/Greycstotration)

with default values you should get in the preview something similar

we DON'T want that we want much more smoothing and we want the smoothing follow and respect imagine edges and structure ..so
A
LOWER " contour preservation "value till the imagine do not start to look blurred (just on that edges not too much more)
B
Now "noise scale" push up the value that will add more blur (but a different kind of blur) here blur. bit too much ... overblurred but still readable
C
here the trick now increase Anisotropy value and you will notice immediately that will compensate the blurriness...
(well not exactly..blurriness remain the same but Anisotropy apply that blur along imagine edges and structures ..so details are regained)
D now that you notice the interaction between "noise scale" and "Asinotropy" you may fine tune the results
(Now ,In this condition you may try some different setting of "Geometry Regolarity " according to the imagine it may change the type of smoothing structure..)
To confront this was the result with default values

while here are the values i chose (quite different from default)you may see how much the effect change confronting the filter preview

with same values on same image you should duplicate exactly mu results.. but my point was also to explain how to adjust that values for different imagines, for that i explain how that value interact
5
Now simply change the layer mode of this duplicated layer in SOFT LIGHT (with till the bug in Overlay mode will be fixed, also mode Overlay will give you same effect..but that may change in the future)
(to check at original size http://www.flickr.com/photos/photocomix ... 4/sizes/o/ )
DONE
Using same values on same image you should duplicate exactly my result: THIS "EFFECT LAYER"

while what i write above on greycstoration settings should help to adapt that values to different imagines

for another confront this http://www.gimptalk.com/io_images/31801 ... kippe.jpeg will be the result if skipping the greycstoration step
No too bad , more sharp and detailed then original but ...less graphic and with less texture and effect
See for example the mountain or even the street and foliage the Greycstoration step allow to give them..hmm..some flow ,that is missed in the skipped version
####################################################################################
HOW BOOST THE FX
DETAIL

to get this instead is very simple

original size http://www.flickr.com/photos/photocomix ... 9/sizes/o/
As additional step just duplicate the "effect layer" (as default duplicate will be in the same layer mode, in this case Soft Light)
HOW TO SOFTEN THE FX
as my nick may suggest i love cartoonish effect, but i know many photographer will prefer something more subtle
Well soften the effect is simple as lower the opacity of the "effect layer(s)" with the opacity cursor in the layer window
############################################################################################
POST SCRIPTUM-(another sample+original xcf+screenshoot of settings + more tips)
ok i think the best if upload another example and also the original xcf file, i should be able to do in a couple of hours
here is a zip with the xcf file http://www.box.net/shared/7q7vqb59ey , the original is in the BG, there is also a copy of the photocopy ( with visibility switched off)
and screenshoot of settings used are here
1

2

3 Effect Layer

Note 1° left default but with i duplicated the layer effect(2 instead then one)- 2 left 1effect layer only in grain merge mode( 100% opacity)


in this case grain merge mode give maybe a more pleasant effective results, but often overlay work better that depend of the imagine
PS
Fencepost i run greycstoration on the photocopy not on the final result...
( but has experiment i did here as ADDITIONAL step, greycstoration was applied first to the photocopy, as explained.
then visible was pasted and i apply greycstoration again to the merged
Also that is interesting Fx but maybe quite strong strong ..may seems the reproduction of a painting
anyway
ORIGINAL
http://farm4.static.flickr.com/3044/272 ... f33e_o.jpg (i do not add here img tag is several MB)
LEFT Default "graphic novel fx"
RiGHT, some greycstoration applied to the merged (with same setting as for the photocopy) and a crop


A last point: as start i used large originals (most 1600x1066 )at quite good resolution
All original are from volterbingen.net except this last, "Market" from http://www.flickr.com/photos/clobrda/ )
