For what it is worth that script in action, not so good it is just an example: https://i.imgur.com/UT5BOoK.mp4  The little original negative image shown in viewnior viewer.

What I expect to know is how to enhance the quality of the positive image on GIMP? 

There are so many options HUE, Brightness, Color Balance, Color Temperature etc. What will be the steps?  Which of the option should be edited first?

It has visualization, but if you change one setting it will apply to the thousands of picture or the whole directory you dropped in it..

For what is worth

Thanks for your advice.

XnConvert is NOT on Ubuntu 20.04 repo

$ apt-cache policy XnConvert

Code:

N: Unable to locate package XnConvert

I ran Flatpak to install it

Steps performed on Terminal;

Code:

$ sudo apt update
$ sudo apt install flatpak
$ flatpak install --user https://flathub.org/repo/appstream/com.xnview.XnConvert.flatpakref
$ flatpak --user update com.xnview.XnConvert

    
Start XnConvert

Code:

    
flatpak run com.xnview.XnConvert

Pls refer to attached screenshot.

Kindly advise where can find XnConvert Tutorial?  Thanks
