Draw an accurate elipse by eye
Knowing how to draw an accurate elipse "by eye" can be an extremely useful tool...i.e., from rendering vases and teacups - not to mention its use in portraiture.
Here's how it is done:
Determine the outside dimensions of your elipse with a rectangle.
Connect the corners of the rectangle with straight lines (CC)
Where these lines intersect is the center, point B
Divide line BC into thirds by eye and mark with dots.
Point D is the outermost dot and will be moved verrrry slightly outward so that it is a little less than 1/3
Mark the center of the sides of the rectangle (Point A).
With a dotted curved line, the elipse will only touch the rectangle at Point A and pass through Point D.
