I'm a newbie, I noticed when you do head modeling, you need two picture, one for the face, and another for the side of the face.
What if I want to create a 3d model of someone and I don't have a picture of the side of his face, or maybe not a symmetrical picture, I mean what if he's smiling but the side picture he's not smiling.
Can you create a head model of someone using only one picture? How?
For instance, this tutorial and many other, use two images.
And finally, say you want to practice by modeling the faces of celebrities or whatever, is there a website that would provide you with two pictures, one for the face and another for the side of the face?
