Curves and gradients for Digital Toning

jamac4k · **Posted:** Mon Apr 06, 2015 4:55 pm **(#1)**

I got a set of .acv curves and converted them to gimp .crv using the acv2gimp.py plugin. These curves are the classic paladium, selenium, silver, sepia, silver gel, platinium and cianotype effects. Some of them are repeated, sorry!.

Gradients was converted from the PSCS6 Photographic Toning suite using cptutils-online from cpt-city.
You can notice that converted .ggr shaws a large name. Any one of you know how rename them. I tried it failfull.
Thanks! and enjoy!

P.S. Gradients must be applied with Gradient Map.

The gradient's name is specified within the file on the second line. I was able to remove all the text between the $$$ and = with the following SED command:

Code: Select all

sed -r -i.bak 's/\$\$\$.*\=//' *.ggr

If you don't mind, I uploaded all of your gradients and curves to my Mediagoblin site. I will remove them if you want me to.

Could you please explain how and where to use that code? Thank you.

- Open a terminal/console/command prompt
- Navigate to the directory with the gradient files
- Copy paste the command (to paste you can likely use the middle button of your mouse, or shift-ctrl-v)
- [enter]

If everything is fine delete the *.ggr.bak files

Thanks Saulgoode and Ofnuts!!!

# Saulgoode: You are free to upload these sets to your host site, but I think that would be better named them as curves and gradients instead my nick. As you like.

Changed dirs to the folder with the gradients, ran the command in the Fedora 20 terminal window and nothing happened except the addition of .bak files. Names remained the same.

The filenames remained the same. Within each of the files, the name of the gradient was changed. To verify, run:

Code: Select all

for i in *.ggr; do diff "$i.bak" "$i";done

You should see output such as:

I did run

Code: Select all

for i in *.ggr; do diff "$i.bak" "$i";done

I guess I was expecting shorter names. This is from within GIMP. Platinum #4 and Platinum #5 are the only two simple names.

I suspect that you missed a step, or that your copying of the renamed gradients into ~/.gimp-2.8/gradients failed for some peculiar reason.

Well yours certainly look better than mine do. I'll start from scratch and see if that makes a difference.

Well now they look fine. Started over. Dunno what caused the mess.

Thank you, saulgoode.
