During the last days I revelead to my friend Issabella my lack of new ideas.
So I remembered that I started my scripting life by translating into a filter a tutorial posted by Issabella. And also during this time I did it another time.
I asked then Issabella whether she could represent a "source of new ideas", which I could then try to translate into scripts.
She accepted.
This is the thread of this "Joint Venture".

She will send me a tutorial, I will try to script it.

Then, if we succeed in producing something nice, she will post the tutorial, I will post the script.

Once done, each GC visitor will have by this way two possibilities:
- lazy people -like I am- can download, install, play with my filter,
- more creative people can download, personalize and apply her tutorial.

There is also the possibility to extend this Joint venture by asking us for new editions, both for the tutorial and the script.

Let's see how this evolves.

Good morning Dinasset and forum Gimp Chat. I must thank how nicely Dinasset has explained the process of this idea.
I wish you all to find the following images nice and it becomes in another new style to follow or play with.
Well, here are the first images. Dinasset and I'll wait for your oppinions

Ah, the power of two
Some great images there Issabella so good luck to you both in this venture and i look forward to the coming scripts/plug-ins.

Where is the tutorial, Issabella?
(note on post #1: she will post the tutorial, I will post the script)

Posted in the first post. Sorry I had a little problem.

OK, Issabella.
Here my filter and a couple of outcomes.
(filter removed because updated in the next post)




note: I will change Plasma to be more random

Updated:
- here the filter updated (random Plasma)

removed, it goes into a loop with certain images; fixed in post #23
- here an outcome

Omg, Nidhogg thanks for your nice comments.
Nidhogg, you did a nice start. Thanks.

After going through the tutorial, I was curious to test the difference if you would use Color to Gray (12-6-6) instead of Sobel.
This eliminates desaturate and invert, shortening the process.

These look awesome.

Thanks to you both for a new view of where I live and best of everything on the launch of your new JV.

Nidhogg, it's interesting what you say. Dinasset and I will check it tomorrow.
Lyle, Thanks
neurolurker, I like your result a lot. A nice view where you live.
