Cornice Moulding for Shaded Drawing
This is a photo of the cornice moulding from class. It is lit from the front and about 45˚ from above and off to the side.
You recieved the cornice profile. Extend the profile lines and shae the drawing with a soft pencil. I have cropped the photo to eliminate the nosing from the very top—you should do this too.
At sharp changes of plane, the edge of a highlight or shadow is crisp. On curved surfaces, the edge of the highlight or shadow is softer and graduated.
- The "local" color is the natural colorand value of the object.
- The "light" color is a light value of the local color used for the most lit portions of the object.
- The "shade" color is a darker value of the local color used for the less-lit portions of the object.
- The "highlight is a very light, opaque value of the local color, mostly used for edges and gossy surfaces.
- The "shadow" is a darker, usually cooler, transparent (thinned) value often painted over the local color as a glaze. The shadow is cast upon the object or another surface. The color of the ambient, or "fill", light is taken into consideration when mixing the shadow color.
In the example above, the dark transparent area below the top highlight is a shadow: It is cast by the overhang and has a shape. The area below the shadow is the local.
Depending upon the object, the angle of light, and the glossiness of the surface, not all values are necessary in all situations. In the example above we see local, shade, and light, but no highlight or shadow.
