Finding in-game "characters"

[Vectif 380]

I assume mostly everyone here knows you can have an in-game custom skin (profile character). I was wondering how to extract "character templates/face skins" from the game's "core". 
I've got most of them since I found them around on the internet, I'm trying to get WhiteHead_20,, mostly known as "Walsh". Does anyone posess the skin template for this character, or know how to get it?

Thanks!
--edit: changed to proper name

Hm, Walsh is actualy face WhiteHead_20, its texture is here: \A3\Characters_F_EPB\Heads\Data\m_white_20_co.paa. Is that what you're looking for?

I can not seem to find the folder containing the faces. I tried accesing from the documents and from Steam. 

Which would be the right way to access it?

Steam route: \Steam\steamapps\common\Arma 3

Documents: \Saved\A3 (but "Characters_F_EPB" doesnt seem to appear here.)

I can not seem to find it with the "Start" search either.

Thanks in-advance.

Another question (this one's unnecessary but would still appreciate an answer.)

Put it under a spoiler since it was mostly off-topic I'd say; is there a reason for custom faces to not look exactly the same (let's say I took a template from in-game and customized it) as the original? The hair (and other parts often) are always a lot brighter when editing, or seeing from profile than ingame, and sometimes it's just skin colour - making nearly no difference. Is there a certain technique or method to follow, or is it just the game?

You can use BankRev app in Arma 3 Tools to extract characters_f_epb.pbo from the Arma3\Addons folder. It's wherever you installed Arma to, so likely it's Steam\SteamApps\common\Arma 3\Addons.

Not sure about the custom faces question. Could be material-related, I guess; I don't know of any intentions to differentiate custom faces.
