I regularly read how-to books for the mental composting only, skipping over the exercises. But when someone here on Newgrounds recommended Marc Brunet's "How to Draw in 30 Days!" video, I for whatever reason felt like following along, more or less in my own way.

I've so far done the first twelve days. The instructions were to draw:

1. Sphere cut in half.
2. Overlapping spheres.
3. Row of spheres in perspective.
4. Sphere with light and shadow.
5. Cylinders.
6. Complex Shape(s).
7. Floating cubes.
8. Eyeballs.
9. Pyramid of cylinders and cubes.
10. Full to half volumes.
11. Two rows of spheres to a vanishing point.
12. Bent or wiggling cylinders.

These exercises can be boring to look over. So I want to show off this filter from my image editing app.

My cheap scanner doesn't copy all the graphite, which is even harder to see when correcting for uneven lighting. This negative filter helps brings out more of the lines and shading from the scan. Isn't it neat? This view seems useful in identifying areas that don't come across as well as they could.
