For some, a work of art in a museum or gallery can require substantial consideration. For others, a passing glance will do. One can choose to read into symbolism, coloration and more—or purely enjoy (or despise) any type of art for aesthetic reasons. For all the aforementioned, and everyone in between, acclaimed painter David Salle’s book “How to See” offers a helping hand. A series of intimate portraits of Salle’s friends (including Jeff Koons and Alex Katz), peers and other inspirational artists, the work introduces the language of art in a way that artists themselves speak it.
