{i} nuance, slight variation; markings used in a drawing to represent varying degrees of light and darkness
A change in the appearance of a carpet due to localized distortions in the orientation of the fibers, tufts or loops Shading is not a change in color or hue, but a difference in light reflection
A technique used to prevent light from the enlarger reaching certain parts of the printing paper so that the exposure can be modified locally
Apparent color shade differences between areas of the same carpet caused by normal wear and/or random difference in pile lay direction It is a characteristic of cut pile carpet It is not a manufacturing defect
This is the art of representing the third dimension of your subject by emphasizing the contrast of illuminated form with dark regions In a portrait study, it relies on keen observation of the light shapes and dark shapes on the face of your subject It is also important to truly represent the edge-line where light and dark shapes share a line Shading is the secret we use to represent a three-dimensional subject on a two-dimensional surface your sketch pad
An effect that can sometimes appear along the seams of no patterned or textured wallcoverings due to heavier ink coverage at one edge than the other during printing
A machine, resembling a well sweep, used in Egypt for raising water from the Nile for irrigation
Shading is the process of determining how the light reflects from an object depending on its shape, orientation, and location with respect to the light source(s) Aladdin employs Faceted, Gouraud, and Phong shading processes, as determined by the user
Slight differences in shingle color that may occur as a result of normal manufacturing operations
Shading is a change in pile direction that results in an apparent change in color due to the light reflecting in different ways Solid color cut-pile carpets will exhibit this more often than textured or patterned carpets This is normal Severe cases of shading are also known as pooling or watermarking This results in a permanent pile reversal that occurs after installation It has no known cause and is usually confined to only certain areas of an installation Pooling or watermarking is not considered a manufacturing defect
(v) A rendering technique simulating the effect of light on the surface of an object The angular relationship between the light and the surface results in a variance in the value (darkness/lightness) of the surface Abrupt changes in value typically indicate an edge between surfaces (faces)
Shading is the protection from heat gains because of direct solar radiation by permanently attached exterior devices or building elements, interior shading devices, glazing material, or adherent materials Permanently attached means (a) attached with fasteners that require additional tools to remove (as opposed to clips, hooks, latches, snaps, or ties); (b) required by the UBC for emergency egress to be removable from the interior without the use of tools
