Hello,
Its a while that I’m creating an adventure game and now its time to make the final graphics, my goal is to have graphics like the game Samorost made by Amanita-Design.
But I have a problem understanding the structure of its graphics. in some shots, they look like digital painting, like this one:

In some other, they look like real photos from very close views of rocks or woods or metals, mixed somehow with each other:

Or this one, it can’t be painting ! but what is it ?

My confusion is because if they are all paintings, why you see so much collage like scenes, if they are all collage, then how on earth you can make something like the first shot !
I searched all the web, spent yesterday in google searching for a clue, but found nothing. can anybody show me a way to do this kind of graphic ? I can do digital painting but not with textures ! these graphics are made with real textures and wrapped perfectly as you look closely, but even in Photoshop when you wrap a picture, it’ll loose so much quality :
what do I do … brain explodes
