Scribble and scale

Pioneer polargrapher and beta tester supreme Kongorilla tested out the scale pixel routines – I think this drawing is exceptional.

Showing that pixel scaling is exactly the tonic that scribble pixel has been waiting for all these years.  He drops some science thusly:

The pixels were scaled to 1.4, if I remember correctly. I set the pixel samples to a much lower value than I would normally. I did one pass (row size 70 or 80) that looked OK, but I wanted more of a value range, so I ran it again at a smaller row size. I masked most of the higher value pixels on the second pass, and used pen lifts, to keep my brights bright.

Which confirms that the controller now has a good set of features to get around what I see as this drawing style’s biggest problem – how to add more darkness without also adding any density to the lightest areas. ┬áVery pleased with that.

Also wanted to mention he’s been using StippleGen:

I never got the hang of stipplegen, but I expect I was just being a doofus.

      • What I find interesting is the vabiarle way in which the “pixels” could be arranged with mosaic tiles whereas our primitive computers are stuck with a fairly limiting X – Y axis arrangement of pixels all arranged perpendicular to these axes. The mosaic artists were seemingly combining some a simple vector- as well as raster-based approach, giving them far more flexibility than a simple grid pattern would allow. I noticed how smooth the jaw lines were in the mosaic tiles and how the computer version leaves a lot to be desired.

    • In the early 90s I saw an article in the good old National Geographic about ciaocne. There was a closeup of a police bulletin board showing photos of various smugglers who got caught with bundles taped to their bodies, with their faces pixelated. For some reason the pixels were interesting, even though at the time computers weren’t.Anyway, I did a few of those images for practice, then tried a few of my own on non-pixelated photos. I found that each pixel contains the mix of all the colors in the pixel. It was interesting, but after 6-7 paintings it was time to try something else.Fun while it lasted, though, and they all sold!
