i was a bit afraid to open the thread when i read the title

but the results are very cool, PhotoComix !

photo comix: good results! have you tried jayprich's specular bumps filter in g'mic? i think that could give some nice highlights to the silver plate one. and i liked the title .

Very nice, PhotoComix. I like it.

Cool effect, PC. You've given some good depth to those images.

Funny title. too.

i tried it, but my result looks bad in comparison to yours, PhotoComix....

so i blurred the original by 10 and then Levels -> Auto

used an aluminum gradient for the EnviroMap



what am i doing wrong and why is my light way too strong ?

Thank Esper

No i didn't try yet ,but now i will do soon

I uploaded both xcf here
https://docs.google.com/file/d/0B3PfZ2r ... sp=sharing
https://docs.google.com/file/d/0B3PfZ2r ... sp=sharing
(Consider only the visible layers, not those with visibility switched off , neither the "negative")

1) i didn't use environmental map at all, i quoted the GnuTux tut because some of his tips on using lighten effects filter, as switch from the default to the lower value possible when use when bump mapping.

Looking the preview with only bumpmap i noticed that was exactly what i wished so i skipped E. map :
: only used bumpmap with 0,01 value


Other differences here i did not use blur at all:
i know gaussian blur is in the steps of the first example of my tutorial ,
but if you scroll down the tut till message 4 you will found the same skeleton image used as example of a slightly different process , even more simple) :

I did not use Gaussian blur but 2 different Gmic Filter Smooth- Anisotropic and Dream Smoothing
Each used on a darkened duplicate of the original layer

Then i changed mode of the upper layer to overlay ,100 opacity, and the combination was already fine, didn't required editing with the level tool

So first i darkened the darker gray of the original,
and yes if i remember well here for some reason automatic level didn't do much, but correct manually was very simple because were almost not intermediate gray tones to take care , and was no need to modify the white tones, only to make the darker gray in the original closer to black
result was



in the tut i posted also the presets i used in Gmic (... as example i change in Dream Smoothing the merging mode )
BTW in case you found complex install preset : from the xcf , in the layer names is embedded the gmic command used , that you may copy and paste in GMIC> Various> Custom Code the disadvantage is that "Custom Code" filter doesn't allow to finetune or modify the values with sliders but only editing the code in the text field .

Nice work on the images.

Hy sorry for the late replies yesterday i could not connect

yes flowers come out really well
For the rest maybe the original incision pattern is too much evident in the children torso and few other details more pre-smoothing (or use as source the gmic-anisotropic layers ) maybe would enhance the silver-engraving effect
I may try later also because before i forgot to kept track of the layer used for bumpmap, i may do now also to explore the differences :
i apply the Lighten Effect plugin always to a "new layer from visible"
for sure the original not edited layer is the less adapt as bumpmap source , and its duplicate with raised contrast and darkened lines looks too sharp
But which of the other layers (Dream Smoothing, Anisotropic Smooth, or their combination ) would work well is not beyond experimentation

@ Akros
come out nice , maybe also here as in graechan example a bit more smoothing would enhance the effect

BTW for me silver and chrome are the most difficult of metallic effect :
for gold, copper, bronze , colors give a great contribute to the final effect and a adapt environmental map may
solve or at least do most of the job
Instead silver and chrome are just gray ,and all the metal effect come from reflections, shininess and the alike ...
