Leon Battista Alberti Light Quotations

I prefer you to take as your model a mediocre sculpture rather than an excellent painting, for from painted objects we train our hand only to make a likeness, whereas from sculptures we learn to represent both likeness and correct incidence of light.

I would have artists be convinced that the supreme skill and art in painting consists in knowing how to use black and white... because it is light and shade that make objects appear in relief.

It seems obvious that colors vary according to lights, because when any color is placed in the shade, it appears to be different from the same color which is located in light. Shade makes color dark, whereas light makes color bright where it strikes.
