Books on art can help improve an artist's skills both by giving insight into the history of different artists and movements and by providing step-by-step instructions. If you aspire to create a work in the style of Cezanne, you might check out an instructional guide like Paint with the Impressionists: A Step-by-step Guide to Their Methods and Materials for Today's Artists. For those who draw, exploring a book like Perspective Made Easy can help to build confidence in the sometimes tricky aspect of perspective.
