Measuring intensity of a shadow

Click For Summary
SUMMARY

The intensity of a shadow is determined by several key factors: the distance of the light source from the object, the apparent size of the luminous object, the intensity of the light emitted, and the opacity of the object casting the shadow. Additionally, the angle of elevation of the light source can influence shadow darkness. Notably, the texture of the object does not affect shadow intensity, while the color and the amount of light reflected by the object play significant roles in shadow formation.

PREREQUISITES
  • Understanding of light source distance and its impact on shadow formation
  • Knowledge of luminous object characteristics, including size and intensity
  • Familiarity with opacity and its effect on shadow quality
  • Basic principles of light reflection and color theory
NEXT STEPS
  • Research the physics of light and shadow, focusing on the inverse square law
  • Explore the role of color in shadow perception and its psychological effects
  • Study the impact of different materials on shadow opacity and texture
  • Investigate advanced lighting techniques in photography to manipulate shadow intensity
USEFUL FOR

Artists, photographers, physicists, and anyone interested in the principles of light and shadow dynamics will benefit from this discussion.

Is there any relation to find it's strength?
I have got some raw data -
1# it depends on distance of light source of the object

2# how big the luminous object really appears from that place

3# intensity of the luminous object

4# how opaque is the object whose shadow is being formed.

angle of elevation sometimes do also influence.

By 'intenisty of a shadow', you mean 'how little light that hits the ground which we see as a shadow'?
 
by it i mean how darker the ground appears i.e how much darker is the shadow.
one more point to be included
#5 intensity/darkness of shadow is not changed by or is independent of the texture of the body.
#6 it also depends on color,and the amount of light emitted or reflected by the body on which shadow is formed.
