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. :) :bigthup
Oldmangrumpy, your outcome is great! I think you have mixed the two methods and the outcome is superb. :hi5
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. :)

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

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

Excellent results, Issabella. :jumpclap

Its certainly easy to get hooked on this thread! I was having some problems with the blur function, so I went and reread the instructions ... makes a difference sometimes by helping to overcome those 'seniors moments'!! Anyway here are some more attempts at hedcut/blur by colour and two with some bumping using the hedcut image, all with some tweaking of course!!

... from a photo of a wallpainting in Tasmania ...
Image

... from a photo of one of my grevilleas ...
Image

and another exhibit from a statues by the sea photo, a lifesize wooden carving cut from the (boring) photo background ...
Image

I obviously need to do further learning on the 'blur by colour' topic, it confused me the first time I looked at it :( but thanks again Garry for these scripts, terrific entertainment.

Nice results Dinasset. Hopefully David will be able to automate this soon. :)

Well one small step for Dinasset, one giant step for OMG.

Lyle I think I followed your BW Stamp/convolution method (whatever that means!) using kiwi fruit not oranges and ended up with this ...

Image

Now to try it out on some portraits; thanks for the methodology Lyle.

a new experiment with Lyle's setting
at the end added a "replace-color" to get the look of a "sanguigna"-drawing

Hi Lyle,

I've played a bit with your pipeline, and this is indeed fantastic :)
I've already added a new filter 'Black & White / Engrave' that reproduces the look of what you've done, with a small script.
I really think I can go one step further and use this as a basis for a 'image to drawing' filter. Here are the results I've got so far.
This is not fully automated yet, but this is only a matter of time.
What do you think about it ?

Definitely some good results so far David. Looking forward to what you come up with the color version. Will check out b/w engrave soon. :)
