VA Week 8
VA Week8
Part 1: Use 1st subject to answer the question and use the own words. (100-150 words)
One of the central concepts of this course is that perception is constructed from limited sensory information and knowledge based on previous experience. This week, we'll discuss how this sensory information is limited by the properties of our eyes. Because we've only experienced the world through our own eyes, it can be difficult to grasp how the world could look differently. In this discussion, we'll explore how the world appears to individuals with impaired visual systems and how it appears to animals with more sensitive visual systems.
(1) Read this article https://news.stanford.edu/news/2007/april11/med-optart-041107.html
to find out how his vision changed, then answer the following questions for Monet or Degas: What was their vision problem? How did it affect their vision? How did it alter their works? (2) You'll learn (or relearn) how we see color by comparing the output of three types of photoreceptors (cones) each tuned to a different wavelength of light. Some people have only two types of photoreceptors. We say they are colorblind, but actually they do see some colors. Dogs are similarly "colorblind", having just two types of cones. However, birds have super color vision, having four types of cones. Discuss: (a) How the world might appear to animals with fewer or more cones. (b) Why it's difficult to know how the world looks to an animal. Feel free to look up additional information, but please use credible sources.

1. For this blog, I decided to pick The Storm by Pierre-Auguste Cot (French, Bédarieux 1837–1883 Paris) because I like how in this painting the background is dark and the focus is all on the man and woman. The background is clearly darker hence the title The Storm but curiously there is no "clear'" water or rain. But even though they are caught up in a storm she is bright and what she is wearing is white but their surrounding areas there is not much emphasize maybe only the path that they are going that is also bright.
To me, her clothes are wet or maybe it's a sheer underdress and they're both covering themselves with her overdress or it’s cloth. The artist put a lot of details on that fabric to make it look realistic it has shadows and highlights making it look like it has texture. Especially where they're holding it all bunch up together, also to make the fabric look more real the front is lighter like the light is in front of them making the back part of the fabric darker.
Both of them have one arm up, the man’s arm is darker and hers is brighter, but she has a hand close to his neck that is bright compared to his arm and chest. I think that since they are both somewhat covered by the fabric the one that has less fabric is him and he is a little more behind her and she is a little more in the front and has more fabric covering her back than her front creating more shadows for him than to her.
What's interesting to me is that both of their feet are pointy it's like the impulse before they run and it has shadow coming out towards the right and the rock on their right side with a shadow confirming that the light is coming from the left side of the painting.
2. The Self-Portrait by Leonora Carrington is a self-portrait of her sitting in a chair with a zebra in front of her and a rocking horse behind her. I am unsure if the zebra is a stuffed zebra or if it is a ceramic zebra. There isn’t much to this painting but, the one thing I noticed the most are the shadows and shading. Shadows are dark spots in a picture where light is being blocked by something. Shadows can create an illusion making the object appear three-dimensional and make a picture appear realistic. Shading is to create depth of the object on the canvas or paper and to create contrast. Shadows can change if the light source moves. For example, if you are using natural light such as sun light, when the sun moves, your shadows will move because the object will be blocking the sun light in different areas and the sun light will hit the object in different areas. For example, the shadow behind the rocking horse is called cast shadow. In this photo, it appears that the light source is coming from the ground. The rocking horse is blocking the light source which is creating the shadow behind the rocking horse. The shadow by the chair is another example of cast shadowing. The light is focusing on the back wall which is why she made the blue appear lighter than the blue wall next to it. An attached shadow is usually lighter than a cast shadow and the light source is not directly hitting the object. In this photo, the shadow under the horse’s stomach would be considered as an attached shadow. Shading and shadows can be hard to create because we often overlook shadows and shading due to our own perceptions. To create shadows, we have to carefully look at the objects that we are drawing. In this photo, Carrington shaded dark areas in her shirt to create depth and contrast in it making it look realistic. Also, she shaded dark areas in her pants to create the illusion to show that she’s sitting down. She shaded where the bend is in her legs to create the illusion that her legs have a bend in them. She did the same in her jacket to create depth.
3. For this blog post I am going to focus on week 2’s lesson about how we see things based on our previous experiences with the world. In the Henri Matisse painting, I immediately see two people dancing. This is interesting because almost nothing about the “people” is anatomically correct. There is no detail in their features. In fact, if you separated out the individual parts of the figures I most likely would not identify them as body parts. For example, the arms are elongated an abstract to the left, but short and joined together on the right. There are no hands to show where one arm ends, and another begins. Any of the arms alone do not look like an arm. But when combined with the other shapes I can tell exactly what they are. When Matisse combined all of these ambiguous shapes you get what clearly looks like people. They almost look like silhouettes or shadows of people, but the colors show that these are the actual figures, not shadows of them. There is also another beige figure all the way to the left toward the middle. It may be an arm and part of a torso of another person, but since I only see this small portion in this abstract style by brain did not assume it was another person at first. Now that I’ve noticed that other figure, I assume there is a circle of people dancing and my mind continued the painting outside of the canvas.
4. This oil painting done by Childe Hassam is of a coastal scene. It has an impressionistic style, with the obvious brushstrokes and various vivid strokes of color. One concept that we have learned in this course that applies to this painting is implicit knowledge of the world. The painting also plays off the two different meanings of the word “see”.
To interpret this painting, we rely on implicit knowledge of the world. The area of the painting that is bright blue with specks of white and yellow would be the body of water. We know our previous experiences and memories of large bodies of water will tell us that is what we are seeing in Hassam’s painting. This isn’t an accurate depiction of water, but the colors used in the painting suggest that is what the artist painted. The rocky mountains are represented by strokes of yellow, various shades of brown, white, and some green and blue. Based on memories, this tells us we are looking at a rocky area. We know that the painting is not exactly how an actual coastal scene would look like in real life since the real world is not made up of brushstrokes, but the way the different elements of the painting are arranged make us interpret this painting as such.
The first meaning of “seeing” relates to the visual stimulus or pattern of light entering the eye. Focusing on the specific colors used in different areas of the painting, the various shapes, and how there are portions of the painting illuminated by bright light while other parts are in the shadows would be examples of this type of seeing. The second meaning of see is what we perceive and this is where we rely on implicit knowledge. We come to the conclusion that we are seeing a coastal scene because of previous experiences of encountering one, whether in photographs or actually being there in person.
