Rendering in Pen & Ink is a neat book, although not all of it pulled me in. The first few chapters were particularly useful, but I lost interest on the chapters regarding composition, drawing from photographs, etc. I've included a few useful quotes.
"The beginner, lacking guidance, is almost sure to purchase things of more diverse types and in larger quantities than is essential. You surely cannot become an artist by the simple expedient of collecting art supplies. If you buy but few things instead, and learn to master them well, trying others only after this mastery has been attained, you will eventually become partial to certain things especially suited to your own individuality. You should not, however, be too hasty or overconfident in condemning or rejecting materials. You cannot heap blame upon a musical instrument simply because you found yourself unable to play it at the first attempt. Like such instruments, materials often have hidden qualities that take long practice to bring into evidence."
“In Chapter 1 we mentioned that actual objects have no true outlines, no definite edges or profiles bounding them that appear as lines. We see one object as distinct from others only because it is lighter or darker, or of a different color, or has shade or shadow tones upon it or about it, or other effects of illumination that define it or detach it from its surroundings.”
“There is perhaps no better way for students to acquire, almost unconsciously, a fundamental knowledge of composition than through practice in arranging and drawing still life objects.”
