A ghost grid is a guide for organising thoughts, information and sketches, that doesn't compete with content.

Content itself can also be the ghost grid to highlight changes and help draw comparisons — as when you might sketch options for extending a house or designing a garden.

A grid is useful for structure and creation but needs to fade back from content or disappear when no longer needed. Like freeing data from its data prison, a ghost grid emphasises content and information without non-data-ink taking attention.

I learned the term ghost grid from Edward Tufte's Seeing with Fresh Eyes: Meaning, Space, Data, Truth.

I rarely buy other notebooks for work than a dot grid, preferably in a funky colour. Some of my favourites: Leuchtterm dot grid hardcover, Moleskine dot grid softcover, Moo soft cover dotted journals

One of the best things we did when on a significant traveling trip was to make our journal as a mindmap. There are all sorts of reasons why we found it better and more enjoyable to do at the time and better and more enjoyable once returned.

The little things like these make all the difference. Comic artists can only draw realistic bulging muscles because they know what muscles are actually where. Thinking through an object carefully, not superficially, makes a huge difference in being able to represent it well.

Think through the whole object

It’s very easy to draw what we think something looks like, rather than what we’re actually seeing. One of the things art classes teach you is to measure what you’re seeing to not let your eyes be fooled by your common sense. An art teacher in a class at Berkeley once, memorably, sat on the classroom floor to illustrate foreshortening like I’ve shown here. It has stuck with me.

Draw what you see, not what you think

In two-point perspective, we draw our vertical lines, vertical. In three-point perspective, our vertical lines are at an angle, converging on our third vanishing point above or below. 

The simplest way to experience third-point perspective is to stand at the corner of a tall building like a church tower and look up. Not only will the sides of the church converge to vanishing points to either side, but the parallel vertical lines of the tower will appear to converge at some point high in the sky—our third vanishing point.

Three-point perspective makes for a more realistic scene but only becomes apparent when there's enough vertical relief, either up to the sky or below, in what we're viewing. As a result, we most commonly see it in views of downtown skyscrapers, perhaps with a caped or swinging superhero.

Three-point perspective

Lines converge to two points on a horizon.

Perspective can be tricky to get your head around. In drawing and art, using perspective creates the illusion of three-dimensional space on a flat surface. The simplest form to understand is one-point perspective. You will have experienced one-point perspective when standing in a corridor or looking down the center of a street. If you continue the parallel lines of the walls and ground toward the center, they would appear to converge at a central point in front of you at eye level, known as the vanishing point. When real-life features are parallel like this, you can use a central vanishing point as a guide to help capture the scene accurately.

The simplicity of one-point perspective makes it impactful. Leonardo Da Vinci, a personal hero of mine, famously employed one-point perspective in his painting of the Last Supper in the Santa Maria delle Grazie monastery in Milan. The vanishing point, carefully placed behind Jesus' head, draws the viewer's attention to the main subject of the scene.
