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:
“I don’t pity any man who does hard work worth doing. I admire him. I pity the creature who does not work, at whichever end of the social scale he may regard himself as being.”
—Theodore Roosevelt (1858–1919)
“But seldom the laurel wreath is seen
Unmixed with pensive pansies dark;
There’s a light and a shadow on every man
Who at last attains his lifted mark—
Nursing through night the ethereal spark.
Elate he never can be;
He feels that spirits which glad had hailed his worth,
Sleep in oblivion.—The shark
Glides white through the phosphorus sea.”
—Herman Melville (1819–1891)
