How many trace layers are you using in the vector program? Playing with that number can give interesting results.

Tracing in either Inkscape or Ai creates one trace object, always in one layer. Then you can ungroup it and sent to different layers.
Is that what you mean, Odin? I've never seen an option to create multilayered trace. Am I missing something?

Sorry, my wording was not right I should have said scans. In the Inkscape options you can change the scans, I think the default is 8.

Oh, I see what you mean now. Thanks for pointing that out, Odin!

One of the earliest artistic effects that I started out with was vector simplication K1TesseraEna (back in the late 1990s/early 2000s) which sort of got me into the whole retouch bug in the first place. Looks like you are well on the way of catching that same bug too. Kudos to living with your future and lifelong disease. lol

Hijaak; believe they are still in business (not sure though). Slow as molassis when the image was bigger then 640X480 (pretty much standard back in the late 90s; lol). :)

Never heard of that program :cool But what you said before, it's not the artistic effects i'm after. Just trying to find out how good is vectorizing for upscaling small size images. What I posted here was kind of cool byproduct of the failed attempt. The original photo is about 450x450, after vectorizing with good enough tracing I can scale it up to any sensible size.
What todays software can do at converting pixels to vector paths is truly amazing.
