Something like this? (Enfuse, not straight GIMP)

[Gimp-user] c2g in Gimp 2.10.12 not performing as in 2.8

2019-08-09 Thread pistikem
thank you, rich404, for this information !  i didn't know about this gmic_gimp
thing - good to know !

now, short question : the large examples you show are processed within gmic with
some manual desaturating techniques, correct ?  you are not using any c2g
algorithm in gmic as we used in gimp 2.8, right ?  one definitely sees a wealth
of more information in the small inserts or insets as compared to the big
pictures !

i am new in this forum (and also in gimp-forum and gimpforums).  how can i
contact the developers as you suggested ?

FWIW - You would have to ask the developers (Maybe you already have?)

The closest I can get is the gmic_gimp plugin and the black-and-white filter

but

It is not consistent. A darker image requires slightly different setting for
contrast and gamma than a lighter image and if you do not know what a Gimp 2.8
c2g looks like, then it is a matter of judgement.

screenshot examples have the Gimp 2.8 c2g as an inset. 

The only advantage with gmic_gimp is

1. Your can save settings to recall them at a later date.

2. It is scriptable.

best of luck with this one.

[Gimp-user] c2g in Gimp 2.10.12 not performing as in 2.8

2019-08-09 Thread pistikem
you are absolutely right, rich404, i observed the same changes in c2g's
rendering pattern with the version changes in GEGL and GIMP, via GUI or CLI.
now, this is very unfortunate. the c2g algorithm is to my understanding truly
unique and very unusual and special, as it adjust pixel contrasts in an 'organic
or neurological or physiological' way, like the original author stated that he
was influenced by neuro-physiological evidence.
i feel this precious piece of code would deserve to be properly maintained
within GIMP and GEGL, or be made publicly available, perhaps ported to Python3. 
i am not aware of any other (photo) image processing algorithm that
'intelligent' to combine data-driven(!) contrast and color information from a
pixel neighbourhood across three channels for the purpose of reducing RGB to one
layer.  i am truly desperate for getting a new c2g version to work with the
appropriate set of adjustable run parameters.  what about a python3 port ?
i still have a few linux boxes with gimp 2.8 running but i don't see that as a
good way out of this problem, perhaps as a temporary solution only...
