Aerial perspective on Concentric Rings
You are in the center.
Ring 1 is about 10 yards out, you should
first notice a value difference 10 yds. out,
find some objects to mark this distance.
Lots of objects in a row are nice.
Within this first ring are the
darkest dark shadows,
not to be repeated
in any other ring.
Magenta and Green
make the darkest neutral
shadows in the foreground.
Ring 2, 15 to 25 yards out.
Ring 3 is 25 to fifty yards out.
Ring 4 is 100 to 500 yards out,
here starts the split analogous
Green and Purple mixed together,
for the bluer distant shadows
of objects and cloud cover.
Ring 5, is 5 miles away. The mountain
shadows are completely made of Dioxine. Purple and Thalo Green and White.
The highlights in this fifth ring are made
by mixing a tint of Purple and Green with the local hue from a closer ring.
Ring 6, Is five to ten miles away.
Purple and Green change to a tinted Ultramarine
Blue.
Ring 7, is from 10 to 20 miles away.
Ring 8, is 50 miles away, a tint of ring
7.
Ring 9, is 50 to 100 miles away, a tint
of ring 8.
Ring 10, is more than 100 miles away and
very close to the sky color.

Rings.
THIS CHART SHOWS 10 COLOR
PROGRESSIONS OF LOCAL AND SHADOW COLORS FROM THE FOREGROUND TO THE BACKGROUND
AND SKY
All Ring 1 foreground noonday shadow
colors change from a
Magenta-Green to Purple-Green shadow
in the middle ground.
Change colors to a tint of Ult.Blue
for the background.
Nine A/M morning shadows are a
neutral dark mix of
Bt.Umber and Ult.Blue.

4 Point Lineal Perspective
The horizon line is 25 miles out at sea if you
are 6-foot tall standing at sea level, it's 200 miles out if you're
on a 10,000 foot high mountain.
The pictures blue line is the horizon line around
you in three 60 degree chunks.
The center section is the only undistorted section
of the three. It can be seen with both eyes at the same time.
This section should be the maximum and normal
width of your landscape support. The dimensions of this support would
vary depending on how far away the support is away from you. |
|
| Each eye is aimed 30 degrees off center, each
eye sees 120 degrees. The full visible horizon in front of you, including
all of your peripheral vision of both eyes is 180 degrees.
For top accuracy use only one eye and keep your head in the same place
and only use that center 60 degrees of overlapped vision.

I made another example drawing - of the same bar tool
| Here is the straight horizon line used in conjunction
with the surrounding concentric ring horizon line.
See how hard it is to relate the 90 degree angle
of a box turned at this angle on a straight horizon, the straight horizon
line would have to be a very long gentle curve. It's simple on a
concentric circle horizon line and the Horizon Bar Tool.
|
| Every square object has a right and left vanishing
point 90 degrees apart on the horizon line. This puts one of the vanishing
points 30° out of any normal 60° painting. |
The box is where your feet are, the horizon line
is where your eye level is.
