Neurobiologist Margaret Livingstone addresses these and many other questions in Vision and Art, a lively look at the science underlying art. She writes accessibly, but with plenty of technical depth, on such matters as the nature of light and the visible spectrum, the organization of visual-image processing, the structure of the vertebrate eye and brain, and individual and culturally conditioned perceptions of color. Using well-known works of art as case studies, she offers fascinating bits of trivia (on, for instance, how pastels are made and why purple dyes are so rare) alongside practical information for artists (for example, how high-contrast contours and evenly distributed luminance attract the eye).
The result is a literate, lucid blend of art and science that will appeal to artists and connoisseurs alike. --Gregory McNamee

"Why do Claude Monet's fields of flowers seem to wave in the breeze?"
"What is the secret of Mona Lisa's smile?"
The first two chapters cover some scientific fundamentals- how light and the human vision works. While this is all very scientific, every effort is made to make it understandable, with plenty of full-color diagrams illustrating the concepts. While these 2 chapters are not the easiest to read, they're not rocket science either, and provide a valuable foundation for the rest of the book. Not essential but VERY useful.
Things start to get interesting toward the end of the 2nd chapter, when we start to understand what a red/green colorblind person sees. But the best stuff starts to come in the third chapter ("Luminance and Night Vision"). Plenty of interesting illustrations are provided in this chapter (like red cherries in a blue bowl, where the cherries appear brighter or darker than the bowl depending on the ambient light, or flickering polkadots), and continues until the rest of a book, making it a truly fascinating read.
Oh, and the explanation on Mona Lisa's enigmatic smile is very convincing.
I definitely recommend this book to anyone interested in both visual art and science.
I also recommend it to anyone who's interested in science and how things work- you'll appreciate some art pieces a lot more after reading this book.
The author gets to the structure of our visual systems, makes them very clear, and tells us things that are lasting and verifiable. Her spirit of personal experimentation shows in the book, and makes us think that looking inquisitively at the world will pay off.
