making a black/white vector kind of video or just black shadows from a green screened face
I was wondering about something, I got this idea after seeing a music video from some german rapper (no idea who it was) anyway he had his face greenscreened and pasted on a wall but all the highlights were removed so there was just pure black on the shadowed areas, just like a graffiti vector where you spray over a cut out made vector on paper or hardboard. Now I was wondering how I could do this effect, I got my friend’s face green screened, but then what?
I removed the bg of course and now just have his head, what I hope to accomplish is to get a vector version of his head in either only black or have his entire head in just 2 colours gray and black to put on top of a plant mutant that’s smoking but I’d like to know how I can do the colouring

the threshold and cc threshold effects will create something similar to what it sounds like you want… just a high contrast black & white face. to further colorize that (to make it black and gray) you could use the tint effect.
you could probably get smoother results by using the tint effect (to make it black and white) and the levels effect to make it high-contrast and tweak the ‘output white’ value to make the whites gray.
if you needed true vectors from this, you’d then have to try layer>auto trace, setting the channel to luminance, then tweaking the settings and applying auto trace to a new layer. you’d need to auto trace again on the alpha channel, so you have the luminance traced layer key over the silhouette of the head…

I sincerely hope you have the chance to reshoot this. I suspect that once you get the footage starting to look the way you want, following Kevin’s suggestions, you’ll discover that you will need to relight it to get it to look the way you want.
Of course, it’s just a guess. We haven’t got a picture for reference of what you shot.

thank you the threshold surely helped =D
I even managed to get out the white by just adding a colour keyand sorry if this was supposed to go into basics >:

Yes. You need to shoot with this sort of thing in mind.
The shadows need to be placed where you want, by moving the lights into the right position. To preview the effect on set, squint at the talent. This will reduce the visible detail in the shadows to your eye.

I’ll surely keep that in mind if I do this again, the footage however was good though as mentioned next time I would move the lights to create moving shadows, we had 3 lights when making the footage, 2 on the sides one straight forward. It was a small school assignment about basic green screening and since our teacher showed us the clip of that rapper I merely got curious and decided to use my friend’s head for a smoking caterpillar like Alice in Wonderland
thank you all for the quick responses =D
