1.7 Space

Space in drawing is all about creating depth and dimension on a flat surface. It's the secret sauce that makes your art pop off the page. By mastering techniques like perspective and shading, you can transform simple lines into realistic scenes.

Understanding space helps you balance your composition and guide the viewer's eye. From overlapping shapes to atmospheric effects, these tools let you craft drawings that feel alive and three-dimensional. It's like giving your art superpowers to break free from the page.

Elements of space

• Space refers to the area within, around, and between objects in a drawing or composition
• Effective use of space helps create the illusion of depth and three-dimensionality on a two-dimensional surface
• Understanding the various elements of space is crucial for creating realistic and engaging drawings

Positive and negative space

• Positive space represents the areas occupied by the subject or objects in a drawing
• Negative space refers to the empty areas surrounding and between the positive space
• Balancing positive and negative space creates a harmonious composition and helps define the subject

• Figure refers to the main subject or focal point of a drawing that stands out from the background
• Ground represents the background or surrounding area that appears to recede behind the figure
• Establishing a clear distinction between figure and ground enhances the perception of depth and hierarchy in a composition

Overlapping shapes

• Overlapping shapes occur when one object partially covers another, creating a sense of depth and layering
• Objects that overlap appear closer to the viewer, while partially obscured objects seem further away
• Strategically placing overlapping shapes can guide the viewer's eye through the composition and establish spatial relationships

Linear perspective

• Linear perspective is a technique used to create the illusion of depth and space on a flat surface
• It relies on the concept that parallel lines appear to converge at a vanishing point as they recede into the distance
• Linear perspective can be categorized into one-point, two-point, and three-point perspective, depending on the number of vanishing points used

One-point perspective

• One-point perspective uses a single vanishing point, typically placed on the horizon line
• Objects facing the viewer directly have their parallel lines converging towards this single vanishing point
• One-point perspective is often used for interior scenes or compositions with a strong central focus (hallways, roads)

Two-point perspective

• Two-point perspective employs two vanishing points, usually placed on opposite sides of the horizon line
• Objects are drawn with their vertical lines remaining parallel, while horizontal lines converge towards the respective vanishing points
• Two-point perspective is commonly used for exterior scenes or objects with angled views (buildings, boxes)

Three-point perspective

• Three-point perspective introduces a third vanishing point, typically placed above or below the horizon line
• In addition to the two vanishing points on the horizon, vertical lines also converge towards the third vanishing point
• Three-point perspective is used for extreme angles or views, such as looking up at tall buildings or down from high vantage points

Perspective grids

• Perspective grids are constructed using the vanishing points and horizon line to create a framework for accurately placing objects in perspective
• These grids help maintain consistency in scale and proportions throughout the drawing
• By using perspective grids, artists can ensure that objects recede correctly and maintain their spatial relationships

Atmospheric perspective

• Atmospheric perspective, also known as aerial perspective, simulates the effect of atmosphere on the appearance of distant objects
• It relies on the principle that as objects recede into the distance, they appear less distinct and their colors become cooler and less saturated
• Atmospheric perspective helps create a sense of depth and realism in landscapes and expansive scenes

Color and value shifts

• As objects recede into the distance, their colors tend to shift towards cooler hues (blues and grays)
• Distant objects also exhibit a decrease in value contrast, with lights and darks becoming more muted and closer in value
• Incorporating these color and value shifts enhances the illusion of depth and atmosphere in a drawing (distant mountains, fog)

Diminishing detail and contrast

• Objects that are further away from the viewer appear less detailed and have softer edges due to the intervening atmosphere
• Contrast in both value and color diminishes as distance increases, resulting in a loss of clarity and definition
• By gradually reducing detail and contrast in distant elements, artists can effectively convey a sense of depth and space (forests, cityscapes)

Creating depth

• Creating a convincing sense of depth is essential for producing realistic and immersive drawings
• Several techniques can be employed to enhance the illusion of depth, including foreshortening, placement on the picture plane, and relative size

Foreshortening of forms

• Foreshortening occurs when an object appears compressed or shortened due to its angle relative to the viewer
• By accurately depicting the distortion of forms as they recede into space, artists can create a strong sense of depth and three-dimensionality
• Foreshortening is particularly effective for objects extending towards or away from the viewer (arms, legs, roads)

Placement on picture plane

• The placement of objects on the picture plane, or the imaginary surface of the drawing, can significantly impact the perception of depth
• Objects placed lower on the picture plane tend to appear closer to the viewer, while those placed higher seem further away
• Strategically arranging elements at different heights can create a sense of depth and hierarchy within the composition

Relative size of objects

• The relative size of objects plays a crucial role in establishing depth and scale in a drawing
• Objects that are closer to the viewer appear larger, while those that are further away appear smaller
• By accurately depicting the diminishing size of objects as they recede into the distance, artists can create a convincing sense of depth (trees, buildings)

Composition and space

• Composition refers to the arrangement and organization of elements within a drawing or artwork
• Effective use of space in composition can guide the viewer's eye, create visual interest, and convey a sense of balance and harmony
• Several compositional principles, such as the rule of thirds, golden ratio, and balance, can be applied to enhance the spatial dynamics of a drawing

Rule of thirds

• The rule of thirds is a compositional guideline that divides the picture plane into nine equal parts using two horizontal and two vertical lines
• Placing key elements along these lines or at their intersections creates a balanced and visually appealing composition
• The rule of thirds helps create a sense of depth by positioning important elements off-center and allowing space for the eye to explore

Golden ratio

• The golden ratio, approximately 1:1.618, is a mathematical proportion found in nature and considered aesthetically pleasing
• Compositions that incorporate the golden ratio often feel harmonious and balanced, with a natural flow and sense of depth
• The golden ratio can be used to guide the placement of elements and create visually appealing spatial relationships (nautilus shell, facial features)

Balance and symmetry

• Balance in composition refers to the distribution of visual weight among the elements in a drawing
• Symmetrical balance occurs when elements are mirrored or evenly distributed on either side of an axis, creating a sense of stability and formality
• Asymmetrical balance involves arranging elements of varying sizes, shapes, and positions to create a visually balanced composition with a sense of depth and movement

Spatial illusions

• Spatial illusions are techniques that manipulate the viewer's perception of space and depth in a drawing
• These illusions can be used to create intriguing and engaging compositions that challenge the viewer's expectations and perceptions
• Some common spatial illusions include trompe l'oeil, impossible figures, and optical art

Trompe l'oeil

• Trompe l'oeil, French for "deceive the eye," is a technique that creates a highly realistic illusion of three-dimensional objects on a flat surface
• By using precise perspective, shading, and detail, artists can create drawings that appear to be real objects or scenes
• Trompe l'oeil can be used to create illusions of depth, such as false windows or niches, or to depict objects extending beyond the picture plane (murals, still life)

Impossible figures

• Impossible figures are drawings that depict objects or structures that cannot exist in the real world due to their paradoxical geometry
• These figures often exploit the viewer's assumptions about perspective and spatial relationships to create visual illusions and a sense of ambiguity
• Impossible figures challenge the viewer's perception of depth and space, creating intriguing and mind-bending compositions (Penrose triangle, Escher's "Ascending and Descending")

Optical art (Op Art)

• Optical art, or Op Art, is a style that uses precise patterns, shapes, and colors to create visual illusions of movement, vibration, and depth
• Op Art compositions often rely on the viewer's perception of figure-ground relationships and the interaction between positive and negative space
• By manipulating the viewer's perception of space and depth, Op Art can create dynamic and engaging compositions that challenge the eye (Bridget Riley's works)

Depicting volume

• Depicting volume refers to the representation of three-dimensional forms and objects on a two-dimensional surface
• Several techniques can be used to create the illusion of volume, including shading, light and shadow, reflections, and transparency
• Effectively depicting volume enhances the realism and depth of a drawing, making objects appear solid and tangible

Shading techniques

• Shading techniques involve the use of value gradations to create the illusion of volume and three-dimensionality
• Common shading techniques include hatching (parallel lines), cross-hatching (intersecting lines), stippling (dots), and blending (smooth gradations)
• By applying shading techniques to objects in a drawing, artists can convey a sense of form, depth, and volume (sphere, cube)

Light and shadow

• The interplay of light and shadow is crucial for depicting volume and creating a sense of depth in a drawing
• Light sources cast shadows and highlights on objects, revealing their form and position in space
• By accurately rendering the effects of light and shadow, artists can enhance the illusion of three-dimensionality and create a convincing sense of volume (still life, portrait)

Reflections and transparency

• Reflections occur when light bounces off a surface, creating a mirror image of the surrounding environment
• Transparency allows light to pass through an object, revealing what lies behind it while still maintaining some visibility of the object itself
• Depicting reflections and transparency in a drawing can add depth, realism, and visual interest, as well as convey the material properties of objects (glass, water)
