Separation of Light and Shadow

  • Lighting Ratio: reducing the unflattering effects of harsh or dark shadows
  • the value of a color is a measure of its lightness or darkness in comparison to a scale of grays
  • Rule of thumb; "In bright sunlight, a newspaper in shadow is darker than a black shirt in the light

Cast Shadows

Cast Shadows

  • when a form intercepts a parcel of direct light, it projects or casts a shadow onto whatever lies behind it
  • the patches of light determine the lightness and color temperature of the shadow
  • a soft light will cast a shadow with a blurry edge, a hard light will produce a harsh edge
  • the edge of every shadow gets softer as the distance increases from the object that casts the shadow
  • the parallel pattern of light and shadow is an effective device to create depth in a painting

Sunbeams and Shadowbeams Sunbeams and Shadowbeams Sunbeams; shafts of light made visible in dust/moisture laden atmosphere occur in rare conditions which must be met in the painting if you want them to be convincing 3 conditions:  a high screen of clouds, foliage, or architecture is punctured by a few openings air is filled with dust, vapor, smoke, or smog the view is towards the sun sunbeams usually shine through uneven apertures using traditional paint, brush a light, semi opaque tone over the dry background where the beams appear Shadowbeams occur most often when a jet contrail aligns with the line of sight the darker beam is usually only visible when there is a light, hazy sky behind it both sunbeams and shadowbeams should be used sparingly because they attract a lot of attention Dappled Light Dappled Light as sunlight passes through the upper leaves of a tree, it covers the ground with circular spots of light each space acts as a pinhole pro...

Premixing

Mixing Color Strings Color string: group of prepared blobs of a given hue mixed in a set of steps from light to dark saves time when painting observationally Free mixing where you use the brush to mix each new stroke from the tube colors Premixing batches of colors prepared in advance Colors should be carefully mixed from observation Advantages: uses less palette surface you can premix generous batches with a palette knife rather than a brush saves time The Reilly Method mix several color strings and use 10 tonal steps for each hue (10 value steps are more than you really need for most paintings) 4 or 5 is a good place to start Gamut Mapping Gamut Mapping the entire group of possible colors for a given painting shown as a polygon superimposed over the color wheel good color comes not just from what you include in a composition, but what you leave out of it Subjective primaries the cleanest mixtures between any two of the starting colors...
