Hello, all:
Revisited G'MIC's Rendering -> Hair lock and reworked its highlighting bits, and in the course of testing it, got carried away. Not often that I post a test suite, but I like how this came out.

In rememberance of Pearl Harbor Day, I've been reading about the Womens' Airforce Service Pilots (US Army Air Force WASPs) who, in World War II delivered newly-built aircraft to operational theaters, and, as with the Tuskegee Airmen, had to fight two wars, the other being the one for simple recognition that they were physically (read: mentally) capable of flying something so complex as a B-17G - but they did, and, on occasion, straight from the production line to operational theaters without so much as an initial test flight. Many years were to pass before they got some of the recognition they deserved and some did not live to enjoy it.
The tutorial for the Hair lock filter is at The Hair lock Filter page in the G'MIC Tutorials. None of the changes I've made affect the user interface or the argument list, though I'm considering retiring the 'Variance' argument in future release, as its effect is so subtle as to be invisible in some cases and its intent can be easily served by overlaying two or three slightly different colored hairlocks.
If time permits, I might write a Gimp Chat specific tutorial based on this particular art work.

Enjoy,
Garry

Looks nice Gary. Forgot about that preset.

Very nice Garry !

@conbagui
IMO you wanted to post on a different topic...(Griatch Christmas Card?)

@grosood
I'm not a digital painter, so I can't try your filter, maybe Griatch..Moko...

Nice results!

Any chance that your technique could be turned into a tutorial?

@Wallace
Just posted this, which is about the care and feeding of the Hair lock filter. The illustration arises from a number of different techniques. If anything other than hair intriques you, post a question here.
@conbagui
`Tis an honor to be confounded with Griatch, for his is a style that I admire. Thank you. And thank you too for your many fine tutorials. I've been using Gimp since 1.0.4 (1996) first on an SGI, yet still you point out matters new to me.
@all
Thank you for your kind words.

Garry

Great thanks, and I'm sure other will really appreciate this.

Nice work here !
