Drawing is a type of visual art that is rendered using various drawing instruments to create a two dimensional medium. Sketches are undetailed drawings or paintings made as an introductory study or an outline. To draw a sketch of a chosen subject, the subject needs to be studied closely. The best angle and aspect of the subject is chosen and kept at eye level. A sketch begins by drawing light and thin lines. The lines drawn are broken and not connected. The sketches are made to scale. The drawing is worked slowly and details are added as the drawn sketch develops. Once the sketch nears accuracy, the broken lines are redrawn using bold and darker strokes.
Making a Draw Sketch:
Sketches are made with various instruments including pencils, charcoal, chalk, pen and ink and silverpoint. Dry media, especially pencil are most preferred since they take lesser time, even though some artists do use watercolors or clay to draw sketches or model sketches. The drawing instruments used to draw sketches are used in a particular way to moderate the look of the image. Hatches are used to create depth and perspective within a drawn sketch. Cross hatches are also used in drawing sketches to create different tones. The density of the breaks is controlled to achieve tone graduation. Pencils and drawing sticks enable continuous tone variations. To get best results the artist draws lines to follow the contours of the surface. Following contour lines creates the effect of depth.
Most artists draw sketch in a linear perspective. This gives the objects in the sketches an appearance of shrinking with distance. Depth is also portrayed by using other techniques. Similar sized objects are drawn smaller as they recede from the viewer. The textures of the objects become compressed as the objects move further away.
