Ok so this was for Digits (Dave) a man so cool he may well be subjet to global warming.
So, few points to make.
1)I would normally scale the camouflage spots down another 1/3 compared toas you can see them here, but i had to do it so you could see clearly what i was doing.
2) i would water down my paint more usually, ii didn't so you could see where the layering 'falls'
3) i normally would spend more time on this, and it would look better, but i needed some pics quick!
Ok so, autumn oakleaf is simply a light spot, on a dark spot on a mid tone background.say hello to this happy chap

we will call him tom.
begin by basecoating you're model in VMC German camo. Black brown (150)

then a layer of 50:50 VMC German Camo. Black Brown and German Camo Pale Brown (144)

Next a layer of German camo pale brown alone, now, this is the 'main colour' this is the mid tone wew discussed earlier, the two previous layers are the shading.

then the camo spotting... now, here's the way to do it from my point of view, use the tip of you're brush (in this case a size 0) to apply small dots, never move the brush just spot it carefully, you will end up with rounded structures which are the idea, have a good mix of sizes of patches and small dots etc. in German camo. black brown (150)

then go over these with light brown (129) leaving a lione of the previous colour all the way around
then go over this with the German Camo Black brown again, breaking up the large light brown areas

then go over some of these with light brown again

you will need to take you're time with this, i usually spend a lot longer than this on mine (my SS themed cadian guard army;)) there is only a couple of hours work on this.
please post thoughts and comments, any questions too, i will edit the first post as i would like to make this as good a guide as possible.
