Straight line drawing plus shading
This week's drawing class was exhausting. The teacher had set up a stack of boxes and pointed some lights at them. Then we talked about "straight line drawings" (which are somewhat easier, supposedly, when your objects have straight lines), points of intersection, how to get perspective right and how to get relative sizes right. Later, he showed us some ways to do shading for the shadows and the relative light and dark sides of the boxes. I felt like I got the shading okay, but the shadows were fairly vague and I made them too dark. Still and all, I can tell they are boxes and I learned a lot.
