Brush fading/manual stippling in Gimp 2.8

Brush fading/manual stippling in Gimp 2.8
Hello,

I'm a paleontology student and in my work I have to create reconstructions and pictures of fossils, most of them stippled (similar to http://24.media.tumblr.com/tumblr_lq6vd5...1_1280.png , http://people.oregonstate.edu/~sidlausb/...tipple.jpg , or http://qilong.files.wordpress.com/2012/0...ippled.jpg ). I used to work with Gimp 2.6, using paintbrush fading set to 1 px (i.e. every click of a mouse making one, perfect dot). I'm using a mouse, because I find it more comfortable and precise than a graphic tablet. Unfortunately, after Gimp update to 2.8 the brush options changed, the brush fading ceased to work as it used to, and I can't find a way to turn it on (tweaking the dynamics settings would probably work for a tablet, but I find it useless for a mouse). I know there are some plugins for automatic stippling/halftoning, but unfortunately they are not what I want, as they obviously mix information about shape (shading) and color, while I need my pictures to show only the shape of the specimens. Is there any way to make the paintbrush fading work in Gimp 2.8 as it worked in Gimp 2.6?

RE: Brush fading/manual stippling in Gimp 2.8
While this is not a stipple brush, I dug into the archives (remembering a similar effect)

Someone was making a video game map & wanted a certain bump-mapping speckled effect.

You can maybe achieve the effect you want in those photos you linked by drawing normal duplicating the layer, adding the effects in the below thread & changing the layermode.

Believe me, when you have to fill a large area with stipples (and pictures are usually quite large), with hundreds of dots, nothing helps more than possibility to drag the mouse all around the field while clicking like crazy Wink. Of course, I can do it slower and stop to put every dot, but that would take much longer and be much more tedious.

Thank you, I'll check it out, but I'm afraid it won't be as accurate, as I would like it to be. While drawing manually, I can control the density of the dots better, showing every character of the specimen adequately. The effect in that thread is more rough and random. It's fine from the artistic point of view, but I'm not sure if I'll be able to make it more subtle.

I was going to post this yesterday but I could not reconcile the one-pixel-per click with the example images, where the dots are anti-aliased and visibly more than one pixel.

However. One pixel per click (or more if you want)

For a single pixel, it has to be the pencil tool.

The size is no problem set the size to 1.

To stop the pixels running into each other by inadvertent mouse movement, set the spacing to a large value. More than three or four hundred enter the value from keyboard.

That gives 1 pixel per click but if you hold the mouse button down you can also paint separate, spaced out, single pixels.
