Hey guys, I've recently started drawing (I'll post some of my portfolio soon) and I've been reading the various Loomis books and the related discussions on this forum. I've been a bit obsessed with the ball and plain method and how to construct a head correctly. I found this thread especially helpful, but I've bastardised it a little and come up with my own.
So I thought I'd share the method that I've come up with, partly because I have some questions but mainly to get your opinions on whether or not its complete bollocks.
I'm not too sure if the measuring methods I'm using are correct? Also, I never know how much of the ball to slice off and how to measure it?
The instructions on the method are below the attached image, please let me know what you guys think, and if you have any suggestions. Thanks!
1. Draw a circle and establish the centre point.
2. Draw a horizontal and vertical line across the centre point.
3. Establish the brow - decide if the head is looking up or down and by how much, then place a horizontal line.
4. Establish the centre of the face - decide if the head is looking left or right and by how much, then place a vertical line.
5. You now have the brow point.
6. Establish the correct angle of the face. To do this we need to understand that the brow point is a flat cross fixed on the sphere, and that however much it is titled up from the centre (for the brow line) this is how much the face plane is angled. So take the distance from the centre of the circle to the brow line (6.a) and (from where the vertical face line intersects with the bottom of the circle) place a point an equal distance in the direction that the head is looking (6.b).
7. Draw a line from the brow point to the point made in step 6, we now have the correct angle of the face.
8. We now establish the ellipse for the brow line. This is based on the principle that if you place two points on opposite sides of a sphere with 180 degrees between them, however much you rotate one point in one direction, the opposite point rotates by the same amount in the opposite direction. So take the distance from the vertical centre line and face line (that we established in step 4) (8.a) and place two points on the horizontal centre line the same distance inwards from the edge of the circle (8b) (8c). These two points are the places where the normal of the brow line ellipse penetrates the surface of the sphere, the one furthest away from the face line is the one we can see, the other is hidden behind the sphere.
9. Now draw a half ellipse from the brow line to these two points, remember that one point is on the opposite side of the sphere, and we can't actually see it.
10. Extend the angle face plane line and mark the chin point, nose point, brow point and hair line. Remembering the principle from step 8 about rotating points, so in this example the hair line will be just out of view.
11. Slice off the sides of the head and mark a cross on the new oval. I've had to estimate here because the hair line is out of view, also I havant worked out what Im doing here…
12. Connect everything up.
