Hard Light
Hard light sources cast shadows whose appearance of the shadow depends on the lighting instrument. For example, fresnel lights can be focused such that their shadows can be "cut" with crisp shadows. That is, the shadows produced will have 'harder' edges with less transition between illumination and shadow. The focused light will produce harder-edged shadows. Focusing a fresnel makes the rays of emitted light more parallel. The parallelism of these rays determines the quality of the shadows. For shadows with no transitional edge/gradient, a point light source is required.
When hitting a textured surface at an angle, hard light will accentuate the textures and details in an object.

Famous quotes containing the words hard and/or light:
“We read that the traveller asked the boy if the swamp before him had a hard bottom. The boy replied that it had. But presently the traveller’s horse sank in up to the girths, and he observed to the boy, “I thought you said that this bog had a hard bottom.” “So it has,” answered the latter, “but you have not got half way to it yet.” So it is with the bogs and quicksands of society; but he is an old boy that knows it.”
—Henry David Thoreau (1817–1862)
“The press is no substitute for institutions. It is like the beam of a searchlight that moves restlessly about, bringing one episode and then another out of darkness into vision. Men cannot do the work of the world by this light alone. They cannot govern society by episodes, incidents, and eruptions. It is only when they work by a steady light of their own, that the press, when it is turned upon them, reveals a situation intelligible enough for a popular decision.”
—Walter Lippmann (1889–1974)
