Query: This is not a book to learn by

The reviewer no one is paying attention to is the more correct one. This book is full of small photos taken during the completion of larger works. Accompanying these photos are plenty of comments, but they are NOT detailed instruction or guidance that will help if you are learning - only generalizations, broad concepts, wishy washy artsy fluff. Don't buy this book to learn to paint shiny objects, fur, cloth or folds, or any other specific material or texture. On the other hand, if you like Joseph Sheppard's style of painting and you can learn to paint anything simply by looking at hundreds of 2-3 inch square photos... this is the book for you.
