Leonardo da Vinci beat Lambert to the punch as did Andrea del Verrocchio, Leonardo’s early teacher and mentor, explaining and diagramming the principles of modeling, which enabled the three-dimension representation of objects and people on a two-dimensional surface. But Lambert formalized the principles in more formal mathematical terms. It was Lambert who used the Latin word for whiteness, albedo. He assigned values to black and white and defined how all the shades of gray in between were to be specified. Black was 0. White was 1. Gray, halfway between was, well half, or 0.5. For those of us not enamored with decimals we can use a range between 0 and 100%, as photographers do.
