sketching

sketching is an unfinished work of art. There are many techniques of sketching and can be accomplished in watercolor, graphite, clay, and pastels. Many famous sketches can be seen in the sketch books of Vincent Van Gogh, Edgar Degas, and Leornardo D Vinci. The artist will quickly catch an impression with a sketch, just like a photograph ,then later they can add colors and details. Not all artists do sketches first. Hatching is a technique using parallel lines close together either light or heavy. This creates light and dark shading. Cross hatching is vertical and horizontal lines crossed by diagonal lines. This usually adds depth and interest to a sketch. Contour hatching is diagonal lines crossing to form diamond shaped fragments or curved lines crossing to add contour to a human figure. Scumbling or ramdom hatching is small scribbles or lines grouped together to illustrate a rough textures or broken surface. Stippling is small dots placed close together or far apart so that the sketch looks smooth and either light or dark in color.
