Art layers are a feature in digital art programs that allow you to separate different parts of your artwork onto individual, transparent sheets, much like traditional cell animation. This division gives you greater flexibility and control over your drawing.
Here's a breakdown:
-
Division of Artwork: The primary purpose of art layers is to divide your artwork into manageable, independent components. You might put the outline of a character on one layer and the color fills on another.
-
Flexibility and Control: This separation allows you to:
- Edit Specific Elements: Change the color of a character's clothing without affecting the outline.
- Reorder Elements: Place a background behind the character, simply by reordering the layers.
- Apply Effects Individually: Add a glow effect to one layer without affecting others.
- Create Animation: Animate different elements separately and then combine them.
-
Analogy to Traditional Cell Animation: In traditional cell animation, artists painted different parts of a character or scene on separate clear sheets (cells). These cells were then stacked and photographed to create the final image. Art layers in digital art software mimic this process.
-
Example: Consider drawing a tree. You could have the following art layers:
- Layer 1: Sketch: A rough sketch of the tree. (Often used as a guide and later hidden or deleted.)
- Layer 2: Outline: The clean, final lines defining the shape of the tree.
- Layer 3: Leaves: The individual leaves, painted or drawn.
- Layer 4: Trunk: The trunk of the tree with shading and texture.
- Layer 5: Background: Sky and any other background elements.
By using separate art layers, you can easily adjust the color of the leaves without affecting the trunk, or move the entire tree in front of or behind other objects in the background. This non-destructive workflow is a core benefit of digital art.
In summary, art layers provide a powerful, non-destructive way to organize and manipulate different elements of your digital artwork, leading to increased flexibility and control.
