What are the three ways to achieve gradation?
Artists use a variety of methods to create gradation, depending upon the art medium, and the precise desired effect. Blending, shading, hatching and crosshatching are common methods. A fading effect can be created with pastels by using a torchon.
What is the result of gradation?
In a gradation and size analysis, a sample of dry aggregate of known weight is separated through a series of sieves with progressively smaller openings. Particle size distribution is then expressed as a percent retained by weight on each sieve size. Results are usually expressed in tabular or graphical format.
Why do we do gradation?
The grading or size distribution of aggregate is an important characteristic because it determines the paste requirement for workable concrete. The more these voids are filled, the less workable the concrete becomes, therefore, a compromise between workability and economy is necessary.
What is gradation value?
Value gradation is used when the edge disappears and the transition from one value to another is smoothed out over a convex or concave surface. Here’s an illustration of a sphere with smooth gradations of value from light to dark.

What are the two types of gradation?
there are two main gradation types categorised by aggregate morphology, namely continuous gradation and gap gradation, or three types by air voids, namely dense gradation, open gra- dation and semi-open gradation.
Which type of gradation is poor?
Poor graded : Poor-graded aggregate is characterized by small variation in size. It contains aggregate particles that are almost of the same size. This means that the particles pack together, leaving relatively large voids in the concrete. It is also called “uniform-graded”.
What is still life drawing?
Still life drawings are drawings of non-living objects, arranged in a specific way, to create meaning or a visual effect. Common still life objects include things like flowers, fruits, vegetables, and other foods and beverages. Dead animals (like wild game and fish) can also be included in a still life drawing…
What is the difference between value and gradation?
Simply defined, value is the gradation from light to dark across a form; it is determined both by the lightness and darkness of the object and by its natural color- its local color – and by the degree of light that strikes it. Value is the range from white to black as seen in a grayscale scale.

What is gradation in principles of design?
GRADATION: A principle of design, it refers to a way of combining the art elements by using series of gradual changes in those elements. Unlike contrast which stresses, sudden changes in elements, gradation refers to a step-by-step change. A gradual change from dark to light values or from large to small shapes would be called gradation.
What are the agents of gradation?
Gradation and Types Gradation is the process of removing unevenness of the land surface and making it a level land. Agents of gradation are running water, wind, glacier, waves, and underground water. Degradation is the process of denudation. It involves weathering, mass wasting and erosion. Aggradation is also known as deposition. Eroded materials are deposited in the depressions or lowlands and these areas rise up.
