The Basics of Visual Literacy

Images contain information and ideas, and visual literacy allows the viewer to gather the information and ideas contained in an image, and place them in context.
FORM
Form refers to the organizational arrangement of the visual elements or the formal qualities of the image. This includes the graphic composition or images (eg shapes, lines, colors, etc) and such things as camera placement, editing and point of view.
A Quick tutorial and review of the range of formal elements used to create images or objects of analysis can be found at:
The set of questions below considers key design elements individually before posing questions to help students understand how they relate to one another.  
  1. COLOR
What is color? Briefly, color is the perceptual phenomena of visible light.
What are its characteristics?
Any given color is described by three general characteristics:
  • Hue: The 'name' of a color - its particular spectrum of visible light
  • Saturation: The amount of gray tones present in the manifestation of the color
  • Value Contrast: The degree of tonality (light/dark) present in the manifestation of the color
For more information, see Color Basics:http://www.worqx.com/color/color_basics.htm
  1. LINE AND SHAPE
Lines join together the smallest of design elements, dots, to direct the construction and placement of objects within an image.   Whether lines construct a recognizable visual element or an abstract visual element, they do so by outlining and forming shapes.   Even the most abstract of shapes has a relationship to some geometrical quality.   As our mind and our vision work together to decode the use of lines and shapes within an image, we seek to understand their relationship to the geometrical building blocks we perceive in our world around us - squares, rectangles, ovals, circles and so on.   Line can also be used independently of shape to suggest or create motion and movement within an image.   To read more about the utility of line and shape in visual design, consult the Online Visual Literacy Project [http://www.pomona.edu/Academics/courserelated/classprojects/Visual-lit/intro/intro.html ].   To experience the way in which line and shape can be used to create both abstract and concrete details in an image, select the link to the descriptive teaching module entitled "All Art is Abstract"http://www.arthistory-archaeology.umd.edu/resources/teaching.html .
III. SPACE
IV. INTEGRATION OF DESIGN ELEMENTS
V. PUTTING IT TOGETHER
The pictorial elements, such as color, line, shape, space and texture, used in designing an image are only one part of the text we read as we explore an image.   Many other elements come into play.   As you think about the image you are exploring, consider whether you think the formal design elements or the thematic relationship of the objects within the image become the focal point of the image for you.   As you do so, think through the following questions:
CONTENT
Content refers to the sensory, subjective, psychological or emotional properties in response to an image. emotional. Content includes:
- the emotional or intellectual message, and
- the expression, essential meaning, siginificance or aesthetic value of an image.
In exploring an image, were your initial observations based on facts, figures, or other information found within the image itself. Does your observation of the image lead you to tell a story about the image. If so, you may wish to explore questions about image content.
CONTEXT
Context refers to the set of circumstances or facts that surround a particular event, situation, etc. This could include when a work of art was made, where, how and for what purpose. This could include historical information on the artist or issues or things the artist references.
Did you raise questions about who produced the image, how it has been utilized, where it has appeared? If so, then you may wish to further explore questions of the context of an image.

Additional Resources

Learning Objective

What do you want your students to be able to do? What do you want your students to focus on? What are you hoping they can get out of using images?
  • ABSTRACTIONThe concept of Abstraction is challenging but fundamental to all art and visual imagery. These execises, questions and additional resources will help students gain a better understanding of the relationship between abstraction and representation in visual images.
  • FRAMING and GAZEThe choices that are made when any image is constructed greatly impacts the viewer's experience. These execises, questions and additional resources will provide skills that enable students to read images with greater understanding.
  • INTERPRETATION 
    These exercises, questions, and additional resources will help students learn how to describe, interpret, and/or compare images.
  • TRANSLATION 
    These exercises, questions, and additional resources will help students learn about the multiple relationships between images and text. Strategies focus on the cognitive processes involved in translating between words and image.
  • CONSTRUCTION These exercises, questions, and additional resources will help students learn how negotiate to the constructed nature of images. Strategies act students to engage visual and multimedia compositions, mediated communication, historical knowledge, and social norms.
  • APPLICATION 
    These exercises, questions, and additional resources will help students learn how to use images to understand and apply theories and key concepts in your field.

Bank of Questions

Questions on ............................. FORM | CONTENT | CONTEXT | FRAME | GAZE
Questions on FORM
  1. Which of the following formal elements most strongly captures your attention when viewing this image: color, line, shape, texture, space, etc? Describe how or why.
  2. Describe the use of color by exploring how it is present or absent in the image you are exploring. You can do so by considering the following questions.   Jot down your impressions along with supportive details as you analyze the image carefully.   NOTE:   While we perceive the color present in a photograph to be 'captured' naturally from nature or the natural environment, color can in fact be manipulated in the development of the photographic image.   Moreover, if the image under consideration is not a photograph, color has been at least or even more selectively chosen.   Think carefully then about the choices of color in the composition of the image you are analyzing. 
    1. What colors do you see?   Are their multiple manifestations of any particular color along the visual spectrum?   Try to distinguish them by their hues (e. g. pink, red, brick) as well as by their degrees of saturation [link tohttp://www.pomona.edu/Academics/courserelated/classprojects/Visual- lit/saturation/Saturation.HTML ] and value contrasts , that is their light/dark tonal elements.   To explore the choice of color in the production of an image, view the following descriptive module explaining Color Theory http://www.arthistory-archaeology.umd.edu/resources/teaching.html .
    2. How do you think the use of color impacts the way in which you experience the image?   On a scale of 1 to 10, note how important the use of color is to you in your interaction with the image and explain why you gave it that numerical rank.   What elements of the image are more or less important than color in your estimation? Does the use of color evoke any emotion in your response to the image?   If so, how would you describe that emotion?
  3. Consider the use of line and shape in the image you are exploring by answering the following questions.
    1. What shapes are present in the image (used either in constructing the objects or the background of the image)?   What shapes are most frequently employed or repeated?
    2. How is line used to create these shapes?   How and when are the lines or they shapes used in dynamic ways to suggest movement?   How and when are they used in static ways that do not imply active motion?
    3. Does the use of line contribute to an illusory three dimensional space in the image?   Does line exist in two dimensional relationships?  
    4. What is the relationship between line and the sensations of texture in the image?   How do line and shape create textural impressions?
    5. How does line/shape combine to create patterns in the image?   What patterns are created?   How do any perceived patterns (including color patterns) owe their design effectiveness to the use of line and shape?  
    6. Is the use of line and shape in the image a more or less powerful visual experience than the use of color in the image?   On a scale of 1 to 10, note how important the use of line and shape are to you in your interaction with the image and explain why you gave it that numerical rank.   Does the use of line or shape evoke any emotion in your response to the image?   If so, how would you describe that emotion?
  4. How is space used in the image?
    1. Does the space seem cluttered, busy, open, white, empty, colorful?  
    2. What compositional designs are incorporated into the use of space?   What types of angles or exterior lighting sources are present or implied?   (If the image is a photograph, consider the selection and use of camera angles.)
    3. On a scale of 1 to 10, note how important the use of space is to you in your interaction with the image and explain why you gave it that numerical rank.   Does the use of space evoke any emotion in your response to the image?   If so, how would you describe that emotion?
  5. How do the elements of color, line, shape, texture, space and so on work together to contribute to the design of the image?   Consider their interactions:
    1. How are these elements arranged and/or balanced together within the image?
    2. Are any of the design elements dominant?   What elements are less dominant?   What would change about the image if you were to change the relationship of the design elements to one another to make another element dominant?   How would your response to the image be altered?
    3. Imagine how you might change the image by varying one of the design elements discussed above.   What element would you vary and how?
    4. What emotion(s) do the combined design elements create for you as you explore this image?   What memories or associations are called up for you by the way in which the design elements are used?   Do you think another viewer might interpret the use of design elements differently?   Why or why not?   Might individual or socio-cultural memories or experiences affect one's response to the design elements?   Why or why not?
  6. How do the pictorial elements, such as color, line, shape, space and texture, relate to the thematic elements of the image?
    1. Is there any written material or use of symbol in the image?   If so, how does it relate to the pictorial elements described above?
    2. In your judgment, what is the function of the image?   How do the formal elements, both pictorial and symbolic, support this function?
    3. Of what significance is the medium (oil, cartoon, photograph, map etc.) in thinking about the formal elements and/or the function of the image?   How would they be altered if the image were to be reproduced in another medium (i.e., an oil painting or a map is photographed)?   How does one explore an image differently is it is a reproduction of an artifact or the artifact itself?
    4. What is the size of the image?   If the image is a reproduction, how is it altered from its original size?   How does this affect one's response to it?  
    5. How do all the formal elements, pictorial as well as textual and symbolic, contribute to your emotional response or intellectual understanding of the image?  

Astronomy Software


In astronomy, there is a wide variety of software. In most cases, there are many different versions of software that do a particular thing. The most common reason for this is preference. While I  use some of these software titles, I am in no way endorsing one brand over another. All of the software listed here are popular among the amateur astronomer population; in fact, it is common for one person to have several different programs that do about the same thing - the features of one might be missing in another, but that other may excel in something else (if that makes sense). For ease, I will break them down into category. Keep in mind this list is not at all complete. If there is a software that is worth mentioning, please send us the link.
The ASP has releaced a PDF file of astronomy related apps for the iPhone and Android. View or download the file.

Planetarium Software | Specialty Observing Programs | CCD Software | Robotic Software | Other Software
Software for OS X (Apple) | New! iPhone/iPod/iPad Apps | New! Palm PDA Apps
Planetarium Software:
This type of software is used to map the night sky from any location on the Earth. It most cases, the software below can print our star charts for a night of viewing and will have extensive databases with at least the most popular night sky objects.
  • The SkyX by Software Bisque is probably the most popular planetarium software available. I also use version 6 of this software. The benefit of using TheSky is their extensive database, ability to remotely control a computerized telescope, and work seamlessly with their other popular product, CCDSoft. Their website also has a Hot Fix section for up to date software updates (you will have to register).
  • The power of TheSky has come to OS X in the form of the new version of TheSky X student edition. TheSky X is now available in the The SkyX Serious Astronomer Edition are available for both OS X and Windows. Windows 7 and 64bit OS's are supported. The previous version, The Sky 6 Professional is still a well respected program that does run on 64bit operating systems but is a Windows only program.
  • TheSky Pocket Edition provides access to the virtual sky from your Palm or Pocket PC. For the diehard astronomer, you can download and extended version of the SAO catalog as well.
  • A free, open-source software called Stellarium is probably a good place to start.
  • Another free planetarium software is Celestia. It runs on Windows, Linux and Mac. This software not only shows you the sky from Earth, but also allows you to "fly" to other locations and view the sky from there.
  • Google Earth is no longer limited to great satellite images of Earth, they have created color images of the space as well. They include Hubble images in places where they belong, and a cool feature is that you can switch the view based on where you live.
  • Microsoft Research has put together an educational program that is nothing short of a breakthrough. The World Wide Telescope allows the user access to just about every image taken from just about every space probe there is. Better still, the user can change the view from radio through to x-ray (visible included of course). It's Windows only, its free so download it now.
  • Keeping with the freeware theme, the third free bit of software is an up-and-coming simple yet capable sky charting program called Asynx Planetarium.
  • Starry Night is a software that uses OpenGL and Quick Time to show a photo realistic night sky. It also provides telescope control. Updates for this software are available at their website, but newer versions allow updates through an application installed with the program.
  • An old style DOS type software by Project Pluto called Guide 8 is also a pretty capable Windows based software as well. While it does not have the pizzazz associated with the "modern" planetariums, it does have what I consider one of the best presentations of nebula. Guide updates are also available on the website.
  • A specialized planetarium software called AstroMB is also available. I have no experience with this software, but it boasts a pretty impressive set of features - available for viewing at their website.
  • SkyMap is another software title I am not familiar with, but it does seem to have a faithful following.
  • Redshift is a program that used to be Macintosh only, and doesn't seem to want to go away. I used it many years ago and found it capable although I have no idea how the newer versions are compared to what is currently available.
  • Sky Tools by CapellaSoft is a bit different from other planetarium software as it has an integrated notepad to store observing notes during observation. While I have no personal experience with this software, this also seems to have a faithful following.
  • SkyChart III by Southern Stars is a planetarium software that is for both Windows and Macintosh.
  • Voyager 4 by Carina Software - a Windows and OS X platform planetarium software, this provides the standard features expected in virtual sky and telescope control.
  • Stellaris — A shareware program for the amateur astronomer
  • Cartes du Ciel/SkyChart - a planetarium program boasting 16 different catalogs boasting its completeness over other software with the same feature. Supports Windows, Mac and Linux and has a few more catalog add-ons available.
  • CyberSky 5 is a run of the mill planetarium program. It offers the standard features in that the night sky can be viewed at any date in time. While not the prettiest program out there, this serves two main purposes: it keeps the price down and speeds up the program. Most new programs use Open GL for that real sky look but comes at the ex pence of computer processor usage, graphics usage and memory usage. I tested this program and found it does what it is supposed to do. It is Windows only program but will run om XP, Vista, and 7 in both 32 bit and 64 bit modes.

Specialty Observing Programs:
These programs are not full featured planetariums, but specialize in specific objects.
  • DeepSky 2011 - I had a chance to use this software and it does a lot. While not as smooth or cohesive as TheSky, it does do several things well. With a bit of a learning curve, one gets a list of available targets for the evening so a plan can be made. An image of the object is available so you have an idea what the target is; so when ready, you can view its location on their built-in chart, send the target info to your goto system and enjoy. From the, note of what you see can also be performed. It keeps a detailed log, and you can share online. Be sure to give it a go!
  • Seeker by Bisque - a 3D immersive tool for traveling through our Solar System
  • VRMars - A virtual reality program that lets you see through the eyes of the Mars Exploration Rover Spirit (The Opportunity MER version is in the works).
  • Night Sky Observer has a program called LunarPhase Pro that is a very capable Lunar observing program. It has imbedded maps, listings of major Lunar features, and Lunar time tables for anything you want to know.
  • Night Sky Observer also has a very nice program called JupSat Pro. It's a program designed to provide information on the four Galilean moons of Jupiter - and does it well.
  • Heavenscape software has a nice program called Satellite Tracker. This program allows full control of a Meade or Celestron computer controlled telescope to track the orbiting satellites - like the International Space Station and various communication satellites.
  • Google Earth is no longer limited to great satellite images of Earth, they have created color images of the space as well. They include Hubble images in places where they belong, and a cool feature is that you can switch the view based on where you live.
  • Microsoft Research has put together an educational program that is nothing short of a breakthrough. The World Wide Telescope allows the user access to just about every image taken from just about every space probe there is. Better still, the user can change the view from radio through to x-ray (visible included of course). It's Windows only, its free so download it now.
  • Halley - Electronic Catalog of Comets. This is a Windows program that maintains a current list of by database. It includes a fast search and export to ECS format.
  • MAXCLOCK - This is a free, highly accurate clock dedicated to astronomy. It provides accurate UT as well as Sun and Moon rise and set time and much more.
  • AstroClock-Now - Another sidereal/UTC clock with a clean Windows interface. Also includes Sun,Moon and planet rise and set times based on observer location.
  • DeepSky - This program is a large and useful program. A quick setup to tell the program where you live will allow it to list available DeepSky objects in view for the evening. There is also an observers log and an optional add-on for telescope control. Click on an object of interest and you are presented with a DSS image. You can view a Moon map and create custom star charts.
