Some mountain and rock photos, industrial stuff, random bits from here and there. The idea is to get some texture out there fast, and then paint over it whatever you want to have in the picture. So a good understanding of values and basics is still required, photos are just another tool for me, and that's how I want to keep it. I don't know how much you know about digital working, so it's kinda difficult to now from what point to explain. And yes, I use a tablet.I have some timelapse videos in Youtube if you want to check them out, you might find them interesting -> www.youtube.com/user/Vablo/vid…
