Introduction<\/h2>\r\nObservational drawing is about learning to see. In our busy and fast-paced society, we are constantly bombarded with imagery. Consequently, our visual attention span seems to only last seconds.\r\n\r\nObservational drawing is about slowing down and spending time learning a new way to see. It is the practiced skill of paying attention to the subject matter in front of you, then figuring out how to accurately convey observed forms in an organized and well-composed fashion on a two-dimensional picture plane.\r\n\r\nThe various components discussed in this chapter are tools to help you better understand and draw observed subject matter. Good observational drawing takes practice, patience, and a few simple techniques that help you draw more accurately. Over time, this technique will become second nature, helping to make the drawing process more efficient.\r\n\r\nIn this chapter, we will go over a few of the most essential skills and techniques that can be used to help your drawings look more realistic and well-proportioned. In addition to techniques from earlier chapters, such as gesture, contour line, and linear perspective, this chapter will explore visual tools and techniques, including sighting<\/strong>, organizational line<\/strong>, plumb and axis lines<\/strong>, and the use of simple tools to aid in proportion and composition. These concepts might seem complicated and cumbersome at first, but they will make a significant difference in your drawings once you build up your confidence with these techniques.\r\n

Visual Tools & Techniques<\/h2>\r\n

Sighting<\/h3>\r\nSighting<\/strong> is a technique used to achieve accuracy and realism in drawing. It is sometimes referred to as measuring, mapping, or sight-sizing. It is one of the most important techniques to master in order to draw from observation. Think of it as a more user-friendly shorthand for drawing in linear perspective, a term we covered in Chapter 5, Perspective Drawing.\r\n\r\nTo sight, an artist uses a simple handheld object as a measuring device to realistically depict subject matter and achieve more accurate perspective without the need for special drawing accessories like long straightedges or large drafting tables. Sighting is a broad term that includes the use of measuring devices such as a viewfinder and sighting tool (skewer stick, pencil, etc.)\r\n\r\nA viewfinder is a frame with an open window that artists use to help translate a three-dimensional reference onto a two-dimensional space. This measuring device also helps artists consider multiple orientations and compositions before starting the physical drawing. This tool will be discussed in depth later in this chapter.\r\n\r\nWhile a viewfinder is helpful, many artists solely use a sighting stick to accomplish all of their measuring needs for comparing objects and creating drawings with accurate proportions. A sighting tool can vary, but many artists use a pencil, a trimmed skewer stick, or even a knitting needle. Whether you're sketching a human figure, still life, complex interior, or a landscape, sighting provides a reliable method for achieving realism by turning the artist's eye, in coordination with a sighting tool, into an effective means of creating accurate drawings from observation.\r\n

Why use Sighting?<\/h4>\r\nThere are many practical reasons to use the technique of sighting when planning your composition, such as:\r\n
