But, any of the other options allows you to create a ring. These
options actually determine how you control the size of the ring.
But, the greater benefi t is that options other than None allow you
to access the Feather Outer Edge and Feather Inner Edge prop-
erties. These feather properties can be adjusted independent of
each other. This facility allows you to create things like an eclipse
more easily than you could with shape layers (Fig. 9.26).

Edge value.
The Ellipse Effect
With default settings, the Ellipse effect creates a circle, simi-
lar to the Circle effect. The difference is that Ellipse allows you
to adjust the width and height of the shape independently, cre-
ating an ellipse instead of a circle if you want. You also have
control over the Inside Color and the Outside Color, as we saw
with Beam. Unfortunately, although the Ellipse effect does have
a Softness (i.e. feathering) parameter, it does not allow us to
feather the inside and outside edges independently. Also, the
Softness property tops out at 100%, which is not always enough
to make this effect look impressive. This effect typically looks
better with a small Thickness value. When the Thickness value is
high, you can see fl at edges on the outside of the shape, which
looks dreadful.
Why Ellipse and Circle were ever created as separate effects,
and not just one mega “round shape” effect, I will never know.
Still, the Ellipse effect can be useful for a quick halo or plan-
etary rings. It's not the best, but creating this kind of object
with the Ellipse effect is much quicker than with shape layers
( Fig. 9.27 ).
