What does a shadow do?
A shadow is light blocked by an object. The object can block all or part of the light. Shadows change size based on how close they are to the light source.
How do you make a shadow longer?
Indoors, you can change the size of a shadow by moving your body or the object closer to or farther from the light. Shadows grow bigger and fuzzier as the object moves closer to the light source, and smaller and sharper as the object moves farther away.

2 Shadows Types: Self and Cast (Umbra and Penumbra).
Why do shadows get blurry?
The blurry edges of everyday shadows are caused by the light sources being extended objects. Light from different parts of the source are able to travel into the shadow area because they emanate from different points in space. The darker, inner part of the shadow where no light can reach is called the “umbra”.
What makes a shadow big or small?
What shadows are used for?
Shadows can be an incredibly useful tool in terms of quickly establishing the all-important focal points of a rendering, by obscuring the areas surrounding a focal point; you are effectively framing part of the image. Additionally, shadows reassure us that objects are sharing the same space.
Why do we use shadows?
Shadows add facet and meaning to an image. Without shadows the object may appear plain and boring. Lights and shadows establish the correlation of one object to another and their place in the full scene. The position and strength of the lights and shadows also set the general mood of the subject.

What makes a shadow clearer?
3 Answers. The finer light source smaller than the object casting the shadow will make the most defined shadow. If you are talking about the partially shaded outer region of a shadow then yes it would be called the penumbra and would be described as Jen says. Or like the area of a partial eclipse.
What is a soft shadow?
Figure 3.20 Hard-edged shadows indicate light from a small point source. In many cases, using soft shadows (which are less distinct and fade off toward the edges, as in Figure 3.21) for some of your lights tends to look more realistic than using only hard shadows.
