Canvas painting is made by stretching canvas over a frame, preparing the surface, and then applying paint to create an image.
Here's a more detailed breakdown of the process:
-
Canvas Preparation:
- Stretching the Canvas: The canvas, typically made of linen or cotton, is stretched tightly across a wooden frame, known as a "stretcher." This frame provides support and prevents the canvas from sagging. The canvas is often secured to the frame using staples or tacks.
- Sizing (Optional): Some artists apply a "size," traditionally rabbit skin glue, to the raw canvas. This helps to seal the fibers and reduce the absorbency of the canvas.
- Priming with Gesso: Gesso, a white acrylic primer, is applied to the canvas. This creates a smooth, uniform surface for painting and prevents the paint from sinking into the canvas fibers. The gesso layer also protects the canvas from the potentially damaging effects of oil paint over time. Multiple coats of gesso may be applied, with sanding between coats, to achieve the desired smoothness.
-
Painting:
- Underpainting (Optional): Some artists begin with an underpainting, a preliminary layer of paint that establishes the composition, values, and color scheme. This can be done with acrylics, oils, or other media.
- Applying Paint: The artist then applies layers of paint to the prepared canvas. Various painting techniques can be used, including layering, glazing, blending, and impasto (thickly applied paint). Artists use brushes, palette knives, or other tools to manipulate the paint.
- Mediums (Optional): Artists often use mediums to modify the properties of their paints, such as their viscosity, drying time, and gloss.
-
Finishing:
- Varnishing (Optional): Once the paint is completely dry, a varnish may be applied to protect the painting from dust, dirt, and UV light. Varnish also enhances the colors and provides a consistent sheen.
In summary, canvas painting involves preparing the canvas by stretching it and applying gesso, then applying paint using various techniques to create an image, and finally, varnishing the finished painting for protection and aesthetic enhancement.
