Photomontage


This photomontage by David Hockney was created by taking many snapshots of one subject and then arranging them in a patchwork to form one image. The resulting image has a similar effect of a peice of Cubist art, and within the cubist paradigm, challenges our notions of depth perception. I also think a correlation can be drawn with impressionist artwork, in that the reality of viewing a scene does not coincide with realist artwork. We do not perceive every detail of a scene in one moment. Our eyes move over the scene, and this requires an interim of at least a few seconds. If you are outside (as this photomontage depicts), environmental shifts in lighting and slight changes in atmospheric conditions have already skewed from one portion of the scene to another. I am not entirely sure how this relates to our discussion of stereopsis, but I am sure that Hockney is challenging our conceptions of depth perception.

Van Gogh's Night Cafe also seems depthful to the viewer. His use of thick paint gives this painting a relief effect. Also the view into the room demonstrates asymmetry which is discussed in Arnheim as a method of portraying depth effect.
I struggled with this assignment and finally decided on this Ben Nicholson, White Relief 1935. This is a painting that connected painting and assemblage, creating a relief effect. This painting does seem depthful as a result of its construction. The circle and square recede and the slim shadows this recession creates illustrate their depth. I thought this was an interesting choice because the lines between sculpture and painting are being blurred.

"A very long tunnel"


The New Yorker cover caught my eye last week as we were talking about depth. The piece, "A Very Long Tunnel" by Brian Stauffer, uses a large range of luminance to portray depth. The symbolism of the piece is enhanced by the use of an exaggerated light source from the back. I also think that it is interesting that the blue part at the back seems to also have depth because of the gradient in light from dark blue, at the top, to light at the bottom. Is this effect similar to that used for atmospheric perspective? This effect seems to make the blue look more realistic while the red has a garish, dusty feeling. Again, the symbolism is enhanced.2008_11_10_p154.jpg

Natvar Bhavsar


While interning at a contemporary art gallery this summer I got to know the work of Indian artist, Natvar Bhavsar very well and was intrigued by his unique method of transferring paint to canvas. He sifts pure, dry color pigment onto each of his canvases without ever physically touching it with his own hands. He would repeat this process over and over again, forming layers of pigment. This created a textured and rhythmic surface which could not have been achieved through traditional brushed on paint. Although it is hard to see in this online image, when you stand in front of one of his works in real life the color jumps out at you and you can clearly see the depth of the paint and how many layers had to be created in order to make the final piece extraordinary. Bhavsar definitely plays with this idea of depth and therefore his paintings are far from flat and two-dimensional.

Depth in Alex Grey's Paintings



While I was looking at pictures for my conference project, I decided to find a painting by the artist I am researching for this assignment. This one, Theologue, struck me as portraying the most depth. In this painting, Grey portrays two parallel planes with the use of grids. However, these grids recede into the painting, much like roads that go on for miles. These planes separate the human figure from the flames below and the mountains behind him, yet the lines flow within the transparent figure as well.

Picasso's "Guitar"

In this collage work by Picasso called "Guitar," Picasso uses 3-D elements to play around with depth in an interesting way.  Picasso is playing around with the idea of depth and the idea of the parts versus the whole.  All of these different pieces on top of each other create a sense of depth among themselves because of the occlusion and the obvious differences in volume among them.  Yet what Picasso is also trying to accomplish here is the idea of a unified whole that is all on one plane--one guitar.  Our eyes go back and forth from seeing this image as different parts on different planes to one unified plane.  I think this game of playing with depth is exactly what Picasso was trying to achieve.

Depth in Egon Schiele's summer landscape

Unlike the typical perspective in which the viewer looks straight into the scene depicted, Schiele elevates the viewer to give an omniscient perspective. As such, not all the conventional depth cues are employed. Occlusion is the primary depth cue. The luminance of the buldings and the sky are consistent throughout the painting, while the foliage is darker. Schiele thus creates a hierarchy which draws the viewer's attention to both the architecture and the horizon. There is no consistent vanishing point and the horizon floats above the foreground. By toying with perspective and depth, Schiele grants the viewer a special and subjective viewpoint which captures a complete picture of the character of the landscape and the architecture within it.

The Chinese Horse.

When we received the depth assignment, I didn't think at first that my conference topic could provide any relevant material. I'm studying the Lascaux Cave - the site of perhaps the most magnificent two-dimensional Paleolithic art ever found - and although the works there are incredible and sophisticated, I don't instantly associate them with depth. The Paleolithic artists who created the paintings did not intend to create realistic scenes complete with a foreground, background, and use of perspective. However, they did utilize several techniques in order to lend their pictures of animals a sense of realistic depth. Some of the depth effects created were unintentional; for example, many animal pictures were painted over with more animals, and the occlusion that results gives the viewer a sense of seeing many animals running in a herd across a plain. Other techniques were used very intentionally. Paleolithic artists utilized their canvas - that is, the irregular surface of the cave walls - in creating their figures. Naturally occurring indents and curves were given a place in the formation of a whole animal. For example, in the so-called "Chinese horse" below ...


... the Paleolithic artist has utilized the small difference in the two surface planes of the cave wall in order to fashion the line of the horse's neck around the throat area. Although it's difficult to see in photographs, researchers who have seen the horse and others like it up close testify to the sense of depth that this technique lends to Paleolithic art.

actions and reactions

Movement can be instigated by and product of forces in the world acting upon one another. I was aware how intricate all the bodily systems are and how easily one influences another, but the discussions of physical, optical and perceptual movement As with most parts of visual perception, the brain has a system of expectation and organization for movement as well. The laws of organization that our brain is accustomed to are broken intoa hierarchical system. The brains inherent belief that if something is in motion, it is less likely to change than if it is stagnant. The brains categorization of movement is further specified as Albert Michotte showed the brain trusts the consistency of directed motion over that of color consistency. I appreciated the incorporation of several types of arts. The discussion of dance made many of the explanations about movement more tangible. Arnheim brings up several times that human body experiences movement in several ways, all effecting one another. The dancer experiences force through motion the viewer experiences the force by watching the dancer move.I though that the image examples in Arnheim for this particular chapter were most helpful. Braque's "Man with a Guitar" evokes the feeling of motion using several techniques.The rigid shapes provide force against the more subdued, blurred back ground. within a painting. The overlapping lines show chaos but somehow provide direction. These same overlaps, along with the color tones and shading create concavities and convexities down the whole piece. He also brings up how important movement is in sculpture. I have seen several pieces of sculpture, especially installations where the space and the movement within it makes the piece.
When I first began this weeks readings I was thinking about how fast our culture moves and it's effect on our visual perception. On p. 384, mentions that our vision has evolved to fit our essential needs for survival. Has our visual attention span been shortened? In the days of MTV and high definition action movies our brains have to be altered from that of someone who lived pre technology. Our visual attention span is only seconds long, I find myself wondering when is our brain at full capacity with visual stimuli?

Dance playing with stroboscopic perception

David Parson’s Caught (1982) demonstrates the use of a strobe light in dance. I think it provides a really interesting way to think about how our brain puts together single moments to create a whole. In this example, the singular moment of a dancer suspended in air has a very different effect than the overall “gestalt” of a dancer leaping over a span of seconds. The long clip shows the whole dance (the strobe light comes in after a few minutes), but the quality is poorer. Watch the excerpt to get a better sense of how the dancer’s movement quality is altered through stroboscopic perception.

Vision and kinesthesia

Livingstone already examined artistic representation as 2-D depiction of a 3-D world. Now she looks at paintings as still depictions of a world full of motion. In a sense we are now urged to think about artistic representation in a 4-D world, with the addition of motion through time as a key aspect of human perception. Arnheim explores the concept that viewing of art always consists of time and motion. The viewer perceives any artistic work using his eye movement to perceive each part through time. However, Arnheim argues that order or eye movement in perceiving a work of art does not matter. Arnheim points to evidence from eye scans (Livingstone shows an example of this on page 78). Does anyone know if there is, in fact, canonical order of eye movements in viewing art? Or in viewing human faces? Arnheim goes on to apply the basic principles of Gestalt to art as 4-dimensional. Through time the brain must grasp the whole significance of artistic works and the whole work must be simultaneously present in the mind. He states that time creates succession, however, the artist (and the brain) must create the order or progression through time.
Livingstone writes about how we maintain stability despite the movement of our eyes and explains that the brain remaps to compensate for eye movement. In studying infant perception for another class, I’ve been intrigued by how perception is inextricable from action and movement. I realized how much we take for granted what our body must do to allow for visual attention. For infants, visual perception, attention and focus is linked with the ability to control body movement, to hold the head and torso upright. There is a huge amount of work done in order to coordinate the motion of the body, the eyes and the external world with visual perception.
Arnheim writes about the distinction between our kinesthetic reactions to inanimate vs. inanimate objects. He argues that endowing inanimate movement with life or consciousness is something that children and artists can access. He gives a great example of a thunderstorm that may be alive to a film director. I find this interesting considering studies of mirror neurons that question whether such neurons are activated by observation of human actions or actions of inanimate objects as well. Interestingly, some studies have showed that people with autism show mirror neuron activation in observations of objects more than in observations of actions of people. This calls to mind the importance of mirror neurons for basic social cognition. I believe that these studies really speak to Arnheim’s discussion of the differences between “expressive impulses and responses” in contrast to “the mechanical effect of physical action (402).” Arnheim seems to see the human body as unique in its motion because of the forces from within the organism. He argues that dance is created more from kinesthetic rather than visual understanding. Considering the evidence from the development of infant perception and the existence of mirror neurons, I believe that visual and kinesthetic senses are perhaps even more closely related than Arnheim states here. In addition, there may be something particular about human action and kinesthetic empathy that is crucial for humans as social beings.

Movement in Film and Literature

Livingston’s discussion on advertising ploys helped me to understand the function of the Where and What system in terms of motion and how consumers can be more attracted to certain types of color schemes and fonts when they are looking to purchase something. The film Fear and Loathing in Las Vegas jumped out at me as I was reading this chapter because it exhibited both Livingston’s point on advertising as well as Arnheim’s point about film editing and how we see motion in general. The jittery and agitated way in which the film is shot parallels its story-line about excessive drug use on the Vegas strip. The Vegas strip alone is notorious for its plethora of neon signs and flashing billboards. Marketers do this intentionally to grab attention and force the viewer to slow down. When letters of one color are placed against an equiluminant background, the words become difficult to read and therefore, one must slow down. Another technique is to create a noticeable contrast between letters and background because the Where system is very responsive to this.

In terms of the film editing that Arnheim writes about, Fear and Loathing in Las Vegas switches from one scene to another using stroboscopic movement as well as choppy transitions. In doing so, the viewer is able to get inside of the minds of these drug addicts and feel like they experiencing the horrible “trip” as well. Finally, Arnheim discusses the three ways in which we perceive motion including—physical movement, optical movement and perceptual movement. He gives the example of a passenger on an airplane and how the cabin seems to be in complete stillness even though there is movement all around. This is how a human normally responds to their surroundings yet this film disrupts this natural tendency of ours to see motion as it exists in the real world.

Another aspect of the reading that interested me was about Shakespeare’s play Hamlet. It does not follow the standard sequence of a story, but instead begins with the most exciting part of the plot (the apex) that would typically be found at the middle or end, and uses that as a starting point for the rest of the play. It opens with the murder of the king, followed by Hamlet’s discovery of the crime and then other events that bring us to the end. Sometimes, challenging the status quo of movement in literature makes for a more thought-provoking story.
