Cast shadow is the shadowed area on adjacent surfaces where the direct light is blocked by the form. It is darker than the core shadow. Its edges are clearly delineated where it is closest to the form, and softer as it stretches away from the form. The shadow is darkest where it is closest to the form.

What is the difference between the shadow and cast shadow when drawing light logic?

If a single light hits a cube, it will make a square shape – if a single light hits a sphere, an ellipse shape. This is called ‘light logic’ and the shadow produced is called a Cast Shadow.

### Which direction are shadows cast?

Shadows will move in the opposite direction of the sun. In the Northern Hemisphere, they will move from west to east, and will point north at noon.

Both cast and self-shadow has different brightness value. Shadows brightness depends upon the reflectivity of object of which they are cast as well as their illumination from other sources. Self-shadow has more brightness than cast shadow since they get more light from surrounding illuminated objects [5].

Why is it important that there is a contrast between light and shadow in artworks?

The depiction of light and shadow is an important technique to represent illusory space in painting. Without light, nothing can be seen but with shadow and shade objects and the space surrounding them can be realistically defined.

## How far do shadows cast?

The length of shadow to your height is proportional to 1/Tangent (sun’s altitude). If the sun is low in the sky (10 degrees), your shadow would be 5.67 times as long as your height. The corresponding ratio at 5 degrees is 11.43 . (So an average height person (5.8 feet) would have a 66 foot long shadow).

Shadows will move in the opposite direction of the sun. In the Northern Hemisphere, they will move from west to east, and will point north at noon. In the Southern Hemisphere, shadows will indicate south at noon. With practice, you can use shadows to determine both direction and time of day.

### What color are cast shadows?

What is a cast shadow in art?

#### What does the strong contrast between light and dark do to a painting or an artwork?

For those of us who love visual drama in painting, an explosion of color against darkness creates an almost entrancing effect and draws in your eye. This contrast of light and dark is one of the powerful ways to bring attention to your focal point.

Core shadows are shadows on the object itself, while cast shadows are the result of the light being blocked by the object. The shadow is then “cast” onto surrounding objects or surfaces.

## Do shadows ever face south?

What is the shadow tip method?

The shadow-tip method is a simple and quick way to determine directions without a compass (see the Shadow Tip illustration on page C-4). Step One. Place a stick or branch into the ground vertically at a fairly level spot where the sun will cast a distinct shadow. Mark the shadow tip with a stone, twig, or other means.
