These first outcomes have been applied blur by cololour - hedcut grey.

These outcomes are in blur by colour - hedcut.

The following ones are being applied blur by colour - hedcut - grey.

and three more.

I realised Garry did a very nice bumped sample. I wanted to get that look he gave to it. Finally and after some questions that my friend Dinasset solved for me, here are two new outcomes similar to the one that Garry did. I hope!

More tries in the style.

I didn't think that I would have a use for this plugin. Then I saw all of Issabella's fantastic work. That inspired me to give it a try. Hope I can get close to Issabella's genius with this.

bilbo9955 what fantastic you are in this thread too. we all learn and enjoy seeing outcomes of others. G'MIC is the best combination with GIMP. Huge thanks to who make it possible with his/her work and talent.

@OMG
I like the way the Nordic landscape fairly scintillates, a nice use of small-scale hedcut pattern. The color scheme, gold, silver and grey-black echos your signature. Another subtle way to sign your image?

@Issabella
I'm a bit shell-shocked by your output. It has been a pleasure these past few days to open this thread up, and like a box of Cracker Jacks, seeing what prize(s) has/have been left inside. The bumpmap collaboration with dinasset almost dissolves these rustic scenes into complete abstraction - but not quite! and the way they teeter betwixt the two interpretations is the charm.

@dinasset
Your winter scene also fairly scintillates. As discussed, a wider range of native scales will be in the next hedcut version; what I have also in mind is to combine step size and smoothing into a single control, that alters the pattern geometry from one of extreme turbulence to one of extreme following-of-edges. Where possible, I always try to reduce the number of user interface sliders and whatnots. Not sure when that will occur. Week or two maybe.

For my next contribution to this thread, a few more thoughts on the combination of Contours->GradientRGB, Testing -> Gmictutorials -> Blur by Color, and Hedcut, also in the testing folder.

I used this image in Finger paint testing: Ambersweet Oranges from the US Dept. of Agriculture gallery. These images are in the public domain in the US, likely in your countries as well.

A hedcut of the oranges: quite a coarse interpretation: image reduced to 800x902.

The hedgecut parameter (top down): 0.863415,0.497561,1,0.902439,1,off,on
Convert the black and white hedcut pattern to a control file for Blur-by-color

using Contours->GradientRGB. It's parameters, top down: 1.75,0,100,on,off
Apply Jerome Boulanger's Details -> Sharpen (Gold-Meinel).

It's parameters: 10,10,2,1,1,7,0,24
Apply Blur-by-color. The highly sharpened oranges are the target image; the GradientRGB converted hedcut pattern is the control image.

Blur-by-color parameters: 3,0.5
Tom Keil's Details->Highpass (for glints and highlights

Highpass parameters: 3.09735,4.98673,off,off. Further enhancement: Colors->autonormalize
Layer merge of Highpass image

layer mode: Color. opacity 17%
That's it. A Lazy brush stroke kind of oranges.

@Issabella - WOW I have just been offline for a couple of days and your outstanding productivity just astounds me. I will now need a couple more days just to catch up with you!!

@Grosood - thank you, I am still very much in learning mode, appreciate your scripts and am enjoying them a great deal. Hopefully there is more to come from me using them over the next few days!

Hope you don't mind a little play w/ your oranges G. I used an old g'mic technique that I've outlined before but it's sort of an iterative technique. I did replace the black background with another texture though. lol

I first use lylejk stencil preset followed by anisotropic smoothing (fake smudge preset that I've shared before) before feeding the result into b/w stamp.

Very cool Lyle !
What is your processing pipeline here ? Do you think this can be automated ?

You guys move on too quickly for me sometimes - I am still coming to terms with just plain old 'hedcut' and how to use it; but still, learning is often not a speedy process.

So here from one of my sculptures by the sea photos is a hedcut image using colouring options as suggested above by Grosood and I also bumped what was a shiny black marble statue with the headcut pattern.

Other then replace the solid back background, I indeed think this can be automated David. I'll just do the flow without the background change. Note, for solid color like this, you could blend noise into the image before going through the steps below to break up the clumpy result, but for this flow, I won't.

First, start with your target image and run lylejk stencil with settings below (lower radius to get the fine detail. Play with this setting gives you either wide lines or closer lines in the end:



Then, you run Anisotrophic smoothing preset. I actually have this setting saved as fake smudge but I went to the actually preset for this flow:



Finally, you run the BW Stamp preset; added just a little smoothing:

By the way, this simple flow works fine for the oranges image, but for a better added step, you can use convolution to amplify the image's essence. I use Bilateral filter for this technique. After you do the anisotrophic step (from the oranges process; not going to duplicate those steps here), you copy the original target above your already processed result and duplicate that. Then run Bilateral preset on the top layer:



You then set the layer property to Grain Extract and merge down. This is your convolution layer. You set this resulting layer to Grain Merge and duplicate several times to taste (i did so 5 times). Then you flatten and run bw Stamp. Below's that result:

Lyle, your treatment to the photo is very good. I'll have to try it too. Although I like more colourful ones, hehe.
Oldmangrumpy, your outcome is great! I think you have mixed the two methods and the outcome is superb.
Here my tries to the last version of Garry's. I hope he likes them. I have to say that I have added more light and contrast to the final outcomes a bit.

Other try.

one more.

The last try.

Wow! Everyone has gotten some great results from this filter.

When I first saw the thread, I did not realize the potential here.

Excellent results, Issabella.
