AW illustrations / photo manipulation

So I have been trawling Flickr for potentially awesome Apocalypse World portraits to use in an upcoming game -- but while I've found a bunch of awesome stuff, using actual photographs for NPCs always seems a little too specific, compared to more abstract line art or illustrations.

Ideally, I'd like to convert the photos I have into something like the AW interior art -- my impression is that these are mostly photos that Vincent has photoshopped into a particular style.

So the question is: Vincent, how did you do it? What filters, layer effects, etc. were used? Non-Vincent people who know what they are doing can also feel free to answer -- or post their own awesome AW NPC art.

(The beginning of my NPC portrait gallery can be found on flickr, here.)

I did them like this.

Great pictures you've got there!

Awesome photos, Daniel. I will be stealing.

Yeah, it's a real shame some of those aren't public domain.

You can also use the Artistic > Cutout filter for a similar effect.

Many of the pictures I used in our last game had that AW two-colour feel to them.

I made them all back in the 90s like this: I take a picture and photocopy it. Then I put another piece of paper over top and a light under my glass table, and I trace out sections of black. Then I colour them in. And done.

That's some old-school style right there, Johnstone. I'll go you one further: in the '80s, we'd tape a pic to a window, tape paper over it, trace and color.

(I think I like this computer-thing better though!)

Yeah, it's a real shame some of those aren't public domain.

Indeed. The gallery is mostly those that I couldn't download, but wanted to have around in any case.
