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:
“They wore the expression men always wore when they watched you dance, staring real hard but locked up inside themselves at the same time, so their eyes told you nothing at all and their faces, in spite of the sweat, might have been carved from something that only looked like flesh.”
—William Gibson (b. 1948)
“Spades take up leaves
No better than spoons,
And bags full of leaves
Are light as balloons.”
—Robert Frost (1874–1963)
