Elements of Design – Space

Space

Space is the interval of distance or area around or between objects. Space on a page is 2 dimensional, but 3 dimensional space can be implied by overlapping elements, changes in size, using perspective, using diagonals or using color and tones. Space contains background, middle ground and foreground. One can perceive space as positive (figure) or negative (ground) depending on its use.

In relation to the Elements of Design, positive space describes the object or subject within the frame. Negative space describes the area around the object or what remains.  Space also refers to the area that a form or shape contains.  Use of space is most recognizable in 3 dimensional objects including sculpture.

 

In the image above, the positive space is the blue squares or figure, the negative space is the dark orange ground. The space an object appears to reside in can be influenced by its placement within the frame. An object placed higher in the frame appears to reside farther from the viewer than an object near the bottom of the frame. In a case like that, the brain creates its own perspective accepting the higher object as more distant.

In this image by Paul Stand, title unknown, we see effective and expressive use of space. If you first view the image as an abstract, the dominant feature in this image is the flat expanse of water stretching into the distance, filling nearly 2/3 of the frame. By focusing on the water, and not the trees, the water and fog appear as a higher-valued (lighter toned) figure or positive space. This allows the brain to see the image as an abstract of darks and light and makes for an interesting tone map.If you find it difficult to perceive the image in this way try squinting your eyes until they are about ½ closed. By removing the detail, the forms, tones, shapes and spaces become more apparent. You can use this technique with most any image. I have also included a tone map of the image just below. The tone map, by itself, is interesting enough, visually, to use as an illustration.

Viewing the Strand image by focusing on the trees and spit of land create a more literal reading of the image and enhance the sense of place and time. The bases of the trees are flooded and convey a sense of isolation and vulnerability within the expanse of the water. By placing the trees to the far left of the frame, Strand has isolated them in their space, further affecting the impact. This impact would have been greatly reduced had he included more land to the left or less water in the fore ground.

Space as we can now see has expressive qualities that enhance our purposes.

Using small spaces between objects can connect them through proximity.
Surrounding an object with lots of blank space or white areas will draw attention to the object.
Overlapped objects or perspective creates a depth of space.
Unequal spacing between similar objects is more dynamic than regimented grouping.
Blank spaces or white areas also create a visual place of rest for the eyes, just as rest intervals in music are the quiet intervals in between notes.

It should be evident by now that most of these elements of design, and the Gestalt elements, do not singularly occur on their own. In most images, you will observe multiple elements at work in concert with one another. This means that attempting to create an image based solely on any one element will be next to impossible.

Elements of Design – Shape and Form

Shape

Shape describes two-dimensional space. The actual defining of shape is done by other elements of design: line, space, value, or color. In combination, these other elements form the shapes we see in a work. Shape occurs when tone or color fills the area between lines. Shape is the brains attempt at resolving an object as recognizable (logical) to one’s experience. In the two-dimensional world, there are three simple geometric shapes – the square, the triangle, and the circle. All other geometric shapes are some combination of these three.

There are also more the more complex organic shapes we see in natural and man-made objects, such as the silhouette of leaves, trees, cars or other everyday objects. Shape is the foundation of form.

Form

Form is the three-dimensional counterpart to shape. Shape is to form as a square is to a cube. In the three-dimensional world, the basic geometric forms are cube, sphere, pyramid, cylinder and cones. Form is shape with dimension or volume. To change a shape to a form, dimension must be created by the addition of tone or color transitions within the shape. This results is the illusion of three-dimensions in a two-dimensional space.

In the first decades of the 20th Century photography was moving away from Pictorialism, the trend of photographers attempting to imitate painterly effects in photos, mostly through soft focus and romantic subject matter.  Some of the influences drawing photographers away from Pictorialism were Dadaism, Cubism and a move toward images in sharp focus. It was during this transitional time that Edward Weston took this early masterpiece of composition, Attic, Glendale, California, 1921. This is clearly a transitional piece borrowing from Pictorialism and touching on elements of gestalt. It also seems to  echo some of the modernist notions of space that were explored in the two decades leading to the production of this image.

This is an image that uses shapes almost exclusively in its design. The framing of the image presents the viewer with an ambiguous space where we don’t know if the central dark form is projecting forward into the space or receding toward the left due to the the figure-ground flip-flops. Is the woman, Betty Katz, leaning against the wall? Or is she looking at it head-on, while being separated from another space on the far side of the projection? A third reading could be of the entire wall being perfectly flat with an abstract design painted on it. The woman’s organic dark form counters the geometric lines and lighter tones of the space. Her size and placement within the frame balance the otherwise expansive mass of shapes and tones.

In this image, Weston is obviously playing with the shapes as geometric planes in space. Texture is non-existent and  any volume in the image is generated by tonal changes determined by the angle of the surface.  The tone map indicates a simple, yet appealing set of lines and tones.

Below is another famous photograph,  this time by the Master Photographer Arnold Newman, Igor Stravinsky, 1946. Even if you don’t know that Stravinsky was one of the 20th Centuries greatest composers, the shapes within the frame leave no doubt that he was connected to music in some way.

This is a very graphic design and just an outline of the shapes would be interesting. Here is another instance where creating a tone map breaks the image down into a collection of shapes without any form or other information. The arrangement of shapes within the frame is interesting for its own design.

Below is another Newman portrait, this time of Alfred Hitchcock, the famous film director/producer and master of the psychological thriller and suspense genre in the middle of the last century. Newman, master of the environmental portrait, has him sitting quite far forward so that his body seems detached from the head in a way that the head seems magically attached yet ready to roll down front by its own weight. Notice the simplicity of the image with only 3 objects in the frame: the forms of the body and head, and the background shape. The graphic quality of the image being obvious.

Returning to Weston, during the middle of his career Edward Weston’s work often concentrated on finding the “essence” of is subject matter. His work by then had evolved from the Pictorialist soft focus image to the sharp, maximum focus practices of the F-64 Group. Now everything possible was in focus and finding the composition leading to a deep connection with the subject was paramount. Form now became important when photographing a subject and the details found in the local contrasts of objects became important. The essence of the object itself became the subject, as well as what the image by itself could elicit emotionally.

In this shot of sand dunes in on the Central California Coast, we see a study of lines, shapes, forms and textures. Weston is using nature’s ever-present design as a subject of its own. This image can be viewed in numerous ways. It can be seen as a realistic study of the land, with all of its details sharply delineated from the foreground to the mountains in the far distance. Alternatively, it might be viewed as a counter-comment to a realistic reading of the image, abstracted into nothing more than a study of shape, form, line, and tone. Still others may see it in a spiritual sense, as an equivalent to a deeply felt personal event or other experience from life. Regardless of Weston’s original intent, he was highly aware of the formal elements of design within the ground glass and used them to his advantage.

The image above, Imogen Cunningham, Leaf Pattern contains some of the elements we have discussed over in the past few posts. See how many of the items you can pick out.  Include any Gestalt elements you might recognize. As a starting point realize the photo is a picture of leaves in front of a white wall and the shadows they cast on that wall.

Don’t think that all of this discussion about line, form, shape etc. is just “old bunk” that no longer applies. Practiced every day, the Elements of Design still hold true and in the worlds of design, publishing, photography and Art. Familiarizing yourself with, and utilizing these concepts, but not letting them control your vision, is one of the best ways to improve your photography. As an exercise, spend the next few photo outings looking for designs in nature or at man made locations, they exist all over. When you find them, spend some time considering the best way to frame them in a way that the design becomes  part of the subject of the image. You will find that over time, your brain will start to connect more with design and you will be utilizing it naturally without effort. The end result will be improved vision and better photographs.

Elements of Design – Line

Line

In his popular art appreciation book, A World of Art, Henry M. Sayer writes:

One of the most fundamental elements of art is line. If you take pencil to paper you can draw a straight line or a curved one. Straight lines can be vertical, horizontal or diagonal. Curved lines can be circular or oval (or segments of circles and ovals), or they can be free-form. Lines can abruptly change direction, in an angle or a curve. They seem to possess direction – they can rise or fall, head off to the left or to the right, disappear in the distance. Lines can divide one thing from another or they can connect things together. They can be thick or thin, long or short, smooth or agitated.”

A line is the mark a moving point describes. A line can vary in weight (heaviness of the mark) and width. A line can also vary in shape, it can have smooth edges, or jagged edges, they can be sharply pointed or blunt. Lines create psychological and emotional responses in the viewer. It can communicate as a symbol or as a motion, by way of its direction. Each of these qualities contributes to the expressiveness of the line.

Lines vary in width. In a pencil drawing, lines are measured in both length and width. A line separating the sky and the edge of a building or horizon I measured by length, it has no width. It only delineates a border. These lines are created by contrasts, changes in color or value.

Martinique, Andre Kertesz, 1972

Image Source

An example exists in the image above, you see a photograph composed entirely of lines, shapes and tones. The line created by the horizon has no width, it is a boundary line, a line delineating two shapes. As mentioned above it is created by a change in contrast.

The wedge shaped strip of ocean above the handrail creates its own flat toned shape and becomes a line. The verticals just below the handrail create a counterpoint to the preponderance of horizontal lines and create a rhythm contrasting with the other flat toned areas in the image. The lines of the handrail and the thin cloud in the middle of the frame both converge toward what is assumed the subject of the shot, a human form behind the glass. It could be argued though that this image is not about the human behind the glass, but purely a study in design. Imagine removing any one element in the image; the glass, the railing the human form, the sky or the ocean.  Would it have the same visual power?

Ask yourself, what would you do to improve on the image given the subject matter? Squint your eyes and look at it as a collection of darks and lights. Does the image seemed balanced in use of line? Also, notice how the image does not seem to use the “rule of thirds” as a compositional device, instead Kertesz successfully uses an “L” armature for the placement.

Lines can be explicit or implicit. A traffic lane line in the middle of the street is explicit. It can be seen, and is an object within the space. A line that is “suggested” by placing objects near each other is an implicit or implied line. In the illustrations above, an implied line exists between the circles. In the first instance, there is an implied line between the two circles. In the second instance there are implied lines running between all three circles, creating a triangle.

An implicit line might also be a line suggested by “motion” within the frame as you see in the image below.

Major line map in Cartier-Bresson image

Major line map in Cartier-Bresson image

In this Cartier-Bresson image, Hyères, France, 1932, the bicyclist is in motion creating an implied line from right to left. The handrail sweeping in from the right reinforces the implied line and directionality of the motion. The bicyclist seems to be in a frenzied hurry. This frenzy is accentuated by the swirling of the handrail starting on the left and connecting visually with the spiral pattern of the steps and the handrail coming in from the right. The steps coming up from the street visually appear to run down to an unknown lower level. All of the swirling lines create a vortex shape enhancing the frenzy. The white line sweeping along the curve of the curbing in the upper part of the frame seems to pen the bicyclist in and hurry him along, squeezing him out of the frame.

Types of lines

Horizontal lines express repose or rest, weight and gravity, and can become the dominant lines in a composition.

Vertical lines express lightness, soaring, spirituality and grandeur, illustrated by looking at both the outside and insides of gothic cathedrals.

Perpendicular lines strengthen the feeling of grandeur and can overpower adjacent horizontals. Combining vertical and horizontal lines create stability, permanence, safety and solidity.

Both horizontals and verticals  create a solidity relative to gravity, as seen in this image by Frederick Evans, A Sea of Steps – Stairs to Chapter House – Wells Cathedral, 1903. Here the massive steps leading to the portal heavily anchor the image. The open archways and vertical relief columns add height to the overall feel, yet retain the solidity needed in the ”sea” of undulating and foot worn steps.

Curved lines express qualities dependent on the amplitude of the curve.

Low amplitude, slow, shallow or soft curves evoke feeling of calmness, relaxation, comfort and safety. They can be familiar and comfortable like old friends. We see these types of line in the natural world on animals, landscapes, plants and ourselves; they are familiar and sensual. They suggest calmness, like a calm sea.

High amplitude, deeply curved, angular or complicated lines on the other hand suggest confusion, anger, disorganization, stress or frenzy. Consider the shape of a turbulent ocean and you will understand the idea.

Leaf Pattern, Imogen Cunningham, 1928

Diagonal lines create instability, tension, motion, direction or depth. A diagonal might create implied movement when isolated; it will appear to be falling in the direction of the lean due to gravity and will create a psychological tension and anticipation. This feeling increases if the diagonal is in proximity to a vertical or horizontal line implying a base.

Using diagonals can give the feeling of distance and perspective like in a photo of a long straight road disappearing in the distance. Used in combination, diagonals effectively create a sense of motion or depth. Diagonals are one of the major tools for creating a three-dimensional feel on the two-dimensional space of the photograph.

Consider the image below titled, L’Aquila, Abruzzo, Italy, 1951. In this image Cartier-Bresson applies diagonals throughout much of the frame enhancing the sense of depth in the image. The procession of women and girls in the foreground creates a crossing counterpoint to the strong diagonal running from the lower right to the mid left side of the image.

Notice also the use of similarity in the repeating form of the two arches coming off the handrail and the black forms of the women in both the foreground and background. Of these two groups note that the groupings also run at the same approximate angle to each other and the iron rails they align with. Each of these elements adds an amount of coherence to the image, making it a stronger composition and allowing the brain to find logic and beauty within the image. Below are image maps of the major lines and tones in the image. Note how tone maps can mimic semi-abstract paintings. In this one we can see the tone masses and how they carry am implication of a thought out design.

Diagonal lines used in non-symmetrical groups create tension, motion, apprehension, disorganization or clutter. Paul Outerbridge, another Master of Photography, understood almost immediately the importance of design in photography. Much of his work shows a heavy concern with composition of tone, shape and line.

Image Mapping – The Basis of a Structural Critique

Herni Cartier-Bresson (1908 – 2004) is considered a Master of Photography, and the greatest of street photographers. One of the first to use a 35mm camera when they were first developed, he spent much of his life traveling the world making images for Life Magazine and Magnum Photos. Though they may appear to be accidental or spur of the moment compositions they were not. He would come across a scene and see its potential in the way the shapes, tones, lines came together. He would then wait for things to happen as people came in and out of the scene. At what he called, “the decisive moment”, he would trip the shutter.  Numerous exhibitions worldwide in major art museums have firmly placed his work as Art and as a model of study. Analysis of his images is a great exercise for those looking to elevate their images above the mundane. For a selection of books on by or about him go to the affiliate Related Reading page.

It can be highly instructive to map out the major lines and line groups in an image. You will often notice interesting patterns which as designs would stand up by themselves. Below are examples of image maps. The first shows not only the major flow  within the image, but also how the verticals in the frame enhance the design. The blue arrows indicate the direction the verticals are converging toward. This strengthens the downward motion of the overall flow. The dotted red arrows indicate the implied motion or direction.

Major and minor line maps for Cartier-Bresson image.

This second map charts the stairs and the two major horizontal lines. It is a good idea to use lighter and heavier line weights to indicate the apparent strength of the line within the frame. In the instance above the lines for the steps are of  lighter weight because because the lines described by the steps are of lower contrast and not as influential is the verticals are. I used the orange line indicate the flow within the image, flow being a type of implied line.

If you used this mapping method to map the tones or values in the image you will see the steps play a greater importance in the image. See one possible example of a tone map for the image below.

Example of a tone map for Cartier-Bresson image.

Example of a tone map for Cartier-Bresson image.


Notice how the tone map appears to have coherence. The shape and tone placements feel comfortable and balanced. Note that even though you cant see actual objects the image still seems to have some motion toward the left.

So the lesson here is that design matters in photography. It can make a weak image strong and help it carry a stronger message. I recently read a forum post where a photographer was invited to help two photo editors select about 30 images for inclusion in a “best of” list. The first task was for each image to be viewed at thumbnail size only and decide very quickly if the image was included or not. Of the images that made it past the first cut, nearly all of them had some kind of “graphic quality” working in their favor. If that doesn’t reinforce the statement that “design matters”, I don’t know what does.

Study the masters in the genre you enjoy and study their compositional techniques by mapping tones, colors, shapes, lines etc. It might even be informative to turn the images upside down and see if the design holds up. If you think about it, all of those people who shoot large format view cameras are composing the images upside down when they look at the ground glass focusing screen.

The more you familiarize yourself with the contents of this site, and study images, the more attuned you will become to the possibilities in front of your lens.

Gestalt – Grouping – Continuity and Prägnanz

Continuity

Continuity is when the grouping of one set of elements easily associates to another. In essence, the eye moves through one element group and into another. The eye takes the path of least resistance. In the figure below left, the eyes will most likely see two X’s grouped together. This is the easiest path for the brain to make sense of because there is little discrimination required for the interpretations. If instead, one focuses on the apex of the angle, they will perceive a chevron, or they may perceive a diamond if they focus in the middle of the form.

In the second graphic, we see a line diverge into two paths. The line creating the least change in the path is the one perceived as being strongest. The path diverging from the norm is the one with the least influence. In this instance, the brain will let the eye follow from the curve in yellow, through to the orange, as opposed to continuing to the straight yellow segment. Continuity occurs easiest along curved or straight lines.

Continuity can also be demonstrated as extending lines that don’t exist, or implied lines. Since the brain wants to continue in the path of least resistance, it may fill in where nothing appears to complete an implied line (a form of closure). Continuity is seen in logo graphics like the one below where the crossbar of the H continues out to the leaf shape.

Prägnanz

The Principle of Prägnanz says that when presented with visual information, the brain will attempt to organize ambiguous information into the simplest form possible. What this is saying is that the brain will process the visual information received into as symmetrical  an image as possible, composed of the simplest shapes possible, and using the least number of shapes possible. So, since the brain’s initial reading of a confused or complex image will be the least complicated possible, any following readings will attempt to deconstruct more complex structures within the frame.

The first illustration in the Continuity discussion above demonstrates this well.  In that instance we see 2 X’s in the initial reading (or maybe a diamond or chevrons) but it is harder to process the whole of the design all in one glance.

The fact that the brain attempts to organize into the simplest shape possible is demonstrated below.

The image shows what appear to be mostly white circles within a black grid pattern. One, the largest white form, takes on more of a square shape. In reality, all of the shapes were made from placing white squares over the grid. Because the smaller shapes do not provide enough information to the brain, it sees them as circles. Circles are a simpler shape than squares. In the case of the largest shape, we see a square because it crosses more than one line in each direction. This provides the brain with more information allowing it to create the more complex square shape.

Another example is the one above. Prägnanz states that the simplest reading is that a circle is positioned behind a square as seen in the first position below, regardless if that were the case in reality. Without Prägnanz we might instead initially perceive the second or third readings below.

Prägnanz goes a long way in explaining the numerous sighting of the vestige of the Virgin or other religious icons in out of the way places like someone’s bathroom window, or the image of a human face on the surface of Mars. Again, we find the brain trying to resolve what it sees into something logical and familiar. A bit more discussion on this can be found by looking up Pareidolia which is a form of Apophenia.

Gestalt – Conclusion

Now that we have covered the principles of Gestalt Perception, it is necessary to point out that these principles do not often occur in isolation. One will not usually exist by itself but in conjunction with one or more of the other principles. Note also that there will be times when the principles do not manifest themselves at all in a given work.

As Richard Zakia states in his book, “Perception and Imaging

“You must not… think of [gestalt principles] as separate, for they are related and work together to facilitate seeing. Visual elements that are close together, that are similar, that form a smooth contour and that allow for closure can produce effective composition.

“Keep in mind, however, that many excellent pictures have been taken that do not conform to the Gestalt [principles] of perceptual organization. Examples of such pictures are those with strong emotional appeal and those that delve into the unconscious. “

Also remember that Gestalt is not considered completely scientific. It tells us what happens, but it doesn’t tell why or how it happens. Research has shown that the elements above happen across a broad population so they can be assumed as reputable guides. Their importance may not be so obvious at this moment, but once we cover the next two major sections, the Elements of Design and the Principles of Art, Gestalt’s  resultant influence  will become obvious. Simply put, the principles of Gestalt help explain why the  Elements of Design and the Principles of Art were able to be developed in the first place. Gestalt is an underpinning of most historical two-dimensional art and the rational basis of much of what has been taught in art school over the past few centuries.

Gestalt – Grouping – Proximity, Similarity, and Closure

Grouping

In physics, any two objects will cause a certain attraction force on each other. They call this gravity. A similar force exists in electromagnetic fields called magnetism. In Gestalt, the attraction force between shapes is Grouping. Just as in the sciences, the attraction force will not necessarily move the other element though there will be an implied, but real, attraction between the two.  Grouping is a major element in Gestalt and can be influences the visual center of an image.

The different types of grouping are: proximity, similarity, continuity, closure and pragnanz. Each is discussed below.

Consider that much of this topic of Gestalt may seem overly simplistic, but it helps to explain the actions of the unconscious mind during the act of viewing and you will see later how it supports the Principles of Art and Elements of Design. If you find it difficult to see the visual relationships described, try closing the eyes and clearing the mind as much as possible, then pay attention to what the eye and brain first perceives in the first second or two when viewing an image.

Proximity

Proximity grouping is the influence objects within close proximity assert on each other. Looking below you will see how a grid of evenly spaced objects is nothing more than a grid of evenly spaced objects. It has balance and logic. Therefore, it is comfortable to the brains and the eyes can rest on it easily.

In the second image, we still have a grid of objects, but the brain accepts each set of double rows as being a single group of objects, though of the same shape. There is still a balance in the logic; it is just a bit more complex. Proximity also works for dissimilar groups of objects, as shown below.

Proximity of shapes affects the visual relationships of shapes within a frame, but the illustration may be a bit too simplistic. In the illustration below we will mix it up just a bit to reinforce the notion.

We now see 3 shapes of blue and 1 shape of grey. How does your brain relate them into groups? Though it is a different color and shape, the strongest reading seems to be that the square is grouped with the 2 overlapping blue shapes. The single blue shape on the upper left is likely grouped with nothing.   Now, consider the grouping in relation to the whole page. A secondary reading may appear grouping all 4 object together when contrasted to the type and page layout. This occurs because there is no framing around the 4 objects presenting them as separate from the balance of the page. This changes their reference and logic, so the brain may see them in either light.

Having too many things in close proximity can affect the  image negatively. This leads to incoherence, not allowing for the eyes to find a comfortable point of focus.

Similarity

Similarity grouping is the influence that objects of like shape can assert on each other. Repetition of shape within the frame creates associations. In the illustration below grouping is mostly by shape. Even though the columns are separated they still associate in the mind. Because they are similar in size and color the grouping seems to be weak.

Color can be used to reinforce Similarity. Most people would see the arrows in this illustration below as being of two different groups based upon their color alone. There is no proximity change needed to induce the effect.

Look at the more complex examples of Similarity in the next two illustrations.

In the  illustration above , the similarity is easy to pick up due to the sameness of the objects in the frame. The lines seem to be one group and the triangles seem to be another.

Now look at the same frame without the triangles. Can you pick out any groupings now? It isn’t as easy because all of the objects are similar. You might see the two adjacent lines on the left side (running diagonally to the right) as being a group due to the similarity of angle. You might also see the two lines running from edge to edge as grouped. There are a number of ambiguous groupings and what you do make out, appears depending on your momentary point of focus.

Comparing the two illustrations show some of the strength in using similarities to create groupings within the frame. Similarities can take the form of colors, as we have seen. They can also be shaped by textures, values, tones, movement, symmetries, etc, as seen below.

Similarity of shapes in an image produce repetition. Repetition in an image can be as strong an element in imaging as it is in music. But too much repetition can become boring, so the best repetition also has an amount of variation included.If you listen to classical music you will have often heard titles including the term, “Theme and Variations”. these are pieces where material structure is repeated while the form changes by changing the melody, rhythm, orchestration, etc. singly or in combination.

How many similarities, or repetitions, can you pick out in the portrait of three peasants by the German photographer, August Sanders? What variations do you find?

Image Source

Keep in mind, too much similarity can cause quick exhaustion on the part of the viewer. Attention needs be paid to placement in this case. For example, an image of a single texture throughout the frame will be boring, while taking swaths of differing shapes or colors of the same texture, arranged in a pleasing way may not.

Closure

Closure is the brain completing what is suggested or implied. It takes the information available and completes it, though not all of the information is presented. Looking at the first illustration below you will perceive a circle, yet it is not a circle but a series of arcs. To make it a true circle the spaces between the lines need to be filled. But we perceive the figure as a circle because the brain performs closure for us. The brain is familiar with the shape and accepts it as whole. The graphic in the second illustration show two forms of grouping at work. At one level, the four triangles group into a star like form due to similarity. However, a square also appears where no square actually exists; the corners do not join. Again, the brain creates a closure of the form (The logo of the World Wildlife Fund seen on the page about figure and ground is an excellent example of closure at work). Notice in the third example how the suggestion of the square is less pronounced. This illustrates how proximity of elements will influence closure. Closure is most noticeable when the elements are near each other. The effect can dissipate with distance or if other shapes intervene. The resultant form suggested can also change. Notice in third illustration how the closure is beginning to describe a circle instead of a square.

Look at another example of closure below. In this case, the frame around the objects cuts off those portions of the blue circle extending outside of the frame. Yet the brain performs completion on it, making it seem whole. In reality, the shape never existed as a circle; it is the same as the green object in the lower right of the frame. Even knowing this will not keep the brain from closing the shape. At times the green shape will seem completed as a circle, with the bottom of the circle protruding through the ground and out of view.

The closure seen above is accomplished by the brain, yet the image creator can make their own closure. Looking at the first image below, notice how the jagged lines do not seem to close with one another. Also that the similarity grouping seems weak.  Yet in the second instance, simply connecting the lines creates closure for us. In this instance, the addition of connecting lines enhanced the closure of unrelated elements and reduced the effect of similarity even more. You will also find there are times where a line from one shape creates an implied closure for another unconnected line.

Symmetry and asymmetry will respectively strengthen and weaken the effect of closure.

In the five groupings above, the first and last show only a little closure due to asymmetry even though they have a strong proximity relationship to their neighbor. The middle three groupings exhibit a certain amount of closure grouping due to their symmetry as well as their proximity.

The image frame influences closure. The frame can both complete the closure, or allow the closure to flow outside it’s boundaries.

The brain will accept continuation of the forms well outside of the frame. Looking at the image of jean Arp by Alfred Neuman, it is easy for the brain to finish the shape of the head. Again, logic born of experience comes into play with the brain completing objects based upon what it knows.
