Re: [Gimp-user] Shadows/Highlights

[Guy Stalnaker <jimmyg521 gmail com>]

Julie,

Welcome to the GIMP. The Shadows/Highlights controls in PS/Lightroom are
pretty nice. As you've discovered there is not an exact equivalent for
GIMP. And as Alexandre indicated, we are on the cusp of a long-worked on,
and long-anticipated new version release, 2.10, that promises significant
new features.

Attached to this reply are two files, one a .scm script file, the other a
.zip file of more .scm files (just easier to send the two :-) These script
files are vintage 2012, so somewhat old (though algorithms used for image
calculations don't really "age"). The standalone file is a
Shadows/Highlights adjustment -- it gives only one parameter, opacity, so
it attempts to modify both shadows and highlights in one go. It may serve
your needs. The .zip file contains a collection of script files one of
which is a shadow recovery script. Also, there is not a highlight analog.
See if these give you acceptable results until we GIMP 2.10 is released and
a more modern tool becomes available.

Use the information here:

https://docs.gimp.org/en/install-script-fu.html

to find out where to put these .scm files so they appear in GIMP for use,
usually on the Filters menu, sometimes on a Filter submenu.

Also, you may find

Regards,

Guy
