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:
“Although I mean it, and project the meaning
As hard as I can into its brushed-metal surface,
It cannot, in this deteriorating climate, pick up
Where I leave off.”

“Stern Daughter of the Voice of God!
O Duty! if that name thou love,
Who art a light to guide, a rod
To check the erring, and reprove;”
