What is Additive and subractive process in art?

Answer 1

In subtractive processes, the sculptor begins with a mass of material larger than the finished work and removes material, or subtracts from that mass until the work achieves its finished form. Carving is a subtractive process. In additive processes, the sculptor builds the work, adding material as the work proceeds. Modeling, construction, and assemblage are additive processes.

Answer 2

Subtractive art is made by taking something away from the art piece to create the interest. Carving a sculpture is subtractive because you take away pieces of the stone. Using an eraser to draw on a graphite-covered surface is subtractive because you are removing graphite.

Answer 3

An additive process in art involves adding material to the piece. A subtractive process involves taking material away from the piece. Coiling a clay pot is additive because you add clay. Carving a stone statue is subtractive because you take away stone.

This is a second answer. I noticed that this question was categorized under color, so if you mean the additive and subtractive process in color mixing, it's a different answer.

The additive color mixing process involves light. The primary colors in light are red, blue, and green. Each of these colors represents one third of the color spectrum. Buy combining red, blue, and green light in varying amounts you can create all colors. This is referred to as additive because you start with black (darkness) and add parts of the spectrum until all parts are present and you have white light. Your computer monitor uses the additive color mixing process, because it has red, blue, and green pixels.

The subtractive color mixing process involves paint, ink, dyes and so on. The primary colors in these media are magenta, cyan, and yellow. Each of these colors absorb one third of the color spectrum. By combining these colors in various combinations, you can in theory create all colors. In practice, because there are no perfect subtractive primary colors available, you will not actually be able to make all colors. Combining all three primary colors makes black in theory. This is referred to as subtractive color mixing because you start with a white surface which reflects the full light spectrum, and you subtract portions of the spectrum by adding magenta, cyan, and yellow color. Adding all will in theory produce black because they would absorb the entire spectrum. Your printer uses the subtractive color mixing process because it has magenta, cyan, and yellow ink. It also has black because as I said, there are no perfect subtractive primary colors, so black helps create a wider range of dark colors.

Answer 4

A subtractive process requires you to take something away from the material. If you use an eraser with charcoal, it is subtractive because it removes charcoal. If you carve a piece of linoleum it is subtractive because it removes linoleum.

Answer 5

Subtractive drawing is a process where the drawing surface is completely covered in graphite or charcoal, then erased to make the image.
