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:
“There’s a line between love and fascination that’s hard to see on an evening such as this.”
—Ned Washington (1901–1976)
“I climb to the tower-top and lean upon broken stone,
A mist that is like blown snow is sweeping over all,
Valley, river, and elms, under the light of a moon
That seems unlike itself, that seems unchangeable,
A glittering sword out of the east.”
—William Butler Yeats (1865–1939)
