I follow the steps as advised previously;

Colors -> Auto White Balance
Colors -> Linear Invert
Filters -> G'MIC-Qt -> Color Temperature -3.5

Quote:That gmic setting does not work for you, not a problem, do not complain and use something else.

You could answer one question though, do you have have python working on your Gimp. Look in the Filters menu. Is there a Python-Fu entry ? (near the bottom of the menu, if it there).

No, Python-Fu entry. Script-Fu is here.

On Terminal run;
$ apt policy python

Code:

python:
  Installed: (none)
  Candidate: (none)
  Version table:
     2.7.15~rc1-1 -1
        100 /var/lib/dpkg/status

Neither Python is on Ubuntu 20.04 repo.  I don't know whether it can run on Ubuntu 20.04.  I can find it out later.  If Python-Fu plugin is necessary then I'll install it.

In case Python unable to run on Ubuntu 20.40, I also have Ubuntu 22.04 and Windows11 running here.  Ubuntu 20.04 is running on my daily working PC

1- G'MIC - Repair - Unpurple (default values) - Due to the purple tone of your negatives
2- Colors - Linear Invert
3- Colors - Levels - Auto Input Levels

In this case, I think you followed the steps in post #33, so as rich2205 commented, it won't make any difference to re-apply Auto Input Levels, as it's been used before.

Follow the steps on #33

1- G'MIC - Repair - Unpurple (default values)
2- Colors - Linear Invert
3- Colors - Levels - Auto Input Levels

Screenshot attached here.  Still it looks slightly different

Steven Lui wants this:

Quote:My planning is;
1. No setting before and after scanning. Download the negative images on PC
2. Batch Post-editing - with 2/3 steps on GIMP (not too many adjusting).  If possible run command-line operation.

So it is a batch, preferably command line. I am no good with command line. Many of the suggestions are GEGL procedures, not easily scriptable.  Lets have some suggestions for a batch.

I'm not knowledgeable on GEGL

GIMP also has Batch Mode

I'm interested to do batch editing running ImageMagick commands
