Chiaroscuro: Renaissance Woodcuts from the Collections of Georg Baselitz and The Albertina, Vienna

This exhibition was well put together and the book does an excellent job of representing the images on display. The plates are in the main large and provide the level of detail that needs to be there. The supporting text is clear and concise giving a real feel for what the artists were trying to achieve.

Can't say that there are a lot of books out there on graphic chiaroscuro, but this one has a good selection of nice examples. After purusing this book and get some decent chiarascuro under your belt, then you can go on to Caravaggio.
