A sphere is the surface of a ball. A ball is a geometric body; the set of all points in space that are at a distance not more than a given from the center. This distance is called the radius of the ball. The ability to draw a sphere correctly is one of the basic ones for an artist, because many objects (or their constituent parts) have a spherical shape, which he will have to capture on paper or canvas. The main task here is to transfer the volume of the sphere on the plane using light and shade.
It is necessary
- - a sheet of A3 paper;
- - easel;
- - pencils of varying degrees of softness;
- - eraser.
Instructions
Step 1
Start drawing with a mental picture of the sphere on a piece of paper: determine the place and size of the future sphere on it. Draw 2-3 straight lines intersecting at one point and set aside equal segments equal to the radius of the ball from the point of their intersection. Don't press down on the pencil. In the final drawing, these lines should not be visible, they are only needed to draw the outline of the ball. It is best to use a hard pencil for this purpose.
Step 2
Connect the resulting points into the correct circle. Then determine from which side the light falls on the ball. Imagine a plane that is perpendicular to the beam of light, dividing the ball in half into the lighted and shaded hemispheres. The area located on the border of these two hemispheres is the most shaded part of the ball.
Step 3
At the point on which the light falls perpendicularly, there is the most illuminated part of the sphere - the flare. On the opposite side of the ball, there is a reflex - the reflection of the incident light rays from the horizontal surface, which gently illuminates the ball from below. Define the contours of the shadow falling from the ball onto the plane of the table.
Step 4
Now, using strokes applied in the shape of the ball, transfer smooth light transitions: from a light highlight, gradually passing to penumbra, then to the darkest part of the ball - its own shadow, and then to the shaded part of the ball, where its surface is gradually brightened by a reflex. Use the softest pencil when drawing in the darkest areas. You can use an eraser to create a highlight effect.
Step 5
Also, with the help of cut-off transitions, draw a falling shadow. It is more intense than the ball's own shadow and has a slightly blurred border. The darkest point in your drawing will be where the ball touches the table surface.
Step 6
It is important that the contours of the ball are not sharply outlined and do not "cut out" it from the general background. Achieve a complete illusion of volume with soft contours and chiaroscuro, giving the impression of a rounded ball shape.
