THIS PRESETS NEED THE LAST VERSION OF THE FILTER UPLOADED A FEW HOURS AGO.
i added the code at bottom of this message
##################################################################
The filter is really versatile and may be used for very extrem and dramatic effect as for more soft retouch

To give a idea of the different possibilities i post some examples, for most if requested i can make a preset

But remember that what can have a very cool effect on a old man face could also have a devastating effect on a girl
portrait

For most devastating Fx scroll to ! VAIOLO!

The last 3 appeal to me, because my realm is on the dark side. Vivid contrast and darkness with some texture = "Perfezione!"

CHIAROSCURO PRESET (thank for the correction ljelyk)

{GN- CHIAROSCURO}{Graphic Novel FX}{gimp_photocomix_booost2}{gimp_photocomix_booost2}{1}{4.36364}{10.4727}{5}{20}{0.12}{14}{0}{0.54}{2.9}{9}{0}{0.93}{1}{0.5}{0.54}{0.78}

Definitely like the CHIAROSCURO; what are the settings for it PC? Makes for a pretty good sketch result.

So maybe you may like

SKIN DISAESE



WORMizer

NOSTALGIA and CHIAROSCURO, I like.

Skin disease would work perfect for my zombie images (Zombie fan). A lighter version of WORMIZER would be more to my liking. Vivid works. Good job, PC.

lylejk i discover that is possible RESURRECT the setting used (if the image was saved as XCF ) when using gimp

The first part of the secret is always use the "new layer" output option, the second is just...copy the layer names

I show
this is a preset of the same filter / a different preset, is for VAIOLO , it make the skins awful and a bit melting away )
{GN- Vaiolo}{Graphic Novel FX}{gimp_photocomix_booost2}{gimp_photocomix_booost2}{1}{7.89474}{6}{5}{20}{0.738462}{14}{0}{0.58}{0.54}{3.59649}{6}{1}{1}{0.5}{0.894737}{4.47368}

This is the layer name of the image you chosed

[G'MIC] Graphic Novel FX : -gimp_photocomix_booost2 1,4.36364,10.4727,5,20,0.12,14,0,0.5,0.54,2.90909,9,0.936364,1,0.5,0.54,0.78

SO... CHIAROSCURO PRESET ( ready to be added to your Gmic_faves if you wish ) is

{GN- CHIAROSCURO}{Graphic Novel FX}{gimp_photocomix_booost2}{gimp_photocomix_booost2}{1}{4.36364}{10.4727,5}{5}{20}{0.12}{14}{0}{0.54}{2.9}{9}{0}{0.93}{1}{0.5}{0.54}{0.78}

Now will be cool a script to get and automatically transform in preset the layers names

THIS PRESET NEED THE LAST VERSION OF THE FILTER ;UPLOADED A FEW HOURS AGO
I ADDED NOW THE CODE IN THE FIRST MESSAGE


CHIAROSCURO is in my previous message ,if is clear how to recover preset from the layer name i may simply upload the xcf, if not...well i will use NOSTALGIA as second example

Good work PC!! NOSTALGIA & FLASH LIGHT are my faves :-)

IMHO it may not be a good idea to apply the disease/worm effects on other people portraits as it can hurt the person.

Pranav i considereted the point but here i clearly used the images for test, testing very delicate and soft effects as more extreme and i show
the original

Anybody is free to apply the restritions he wish on his images i chose that because available for derivative works and i assure no offence to the model were intended and displayed in the first photo of each series
