A very good primer on this style of painting, with many examples and beautiful illustrations. Probably better as a full-sized physical book than as an ebook, as the pictures are a little small on a device, but it's still perfectly readable and has a lot of useful information. I'm an extreme novice at painting, so the step by step examples of how to plan and paint particular pieces were very helpful in getting me to think about composition and how I'd go about getting certain effects. It was also very practical in that it takes you through everything from the different brush and paper types (and where to get them and how to tell if they're good quality) to how to mount and display paintings.
