MIL                          Media
                 What’s In
      In the previous lesson, we learned about Texts Information Media, in this
lesson, we will learn Visual Information and take advantage to its potential for
relaying or understanding messages by identifying the types of visual information
and observe the design elements and principles.
      Visual information entails the use of visual media (that may or may not be
accompanied with audio/sound) in the form of photographs, motion pictures, video
                                                                    recording,     graphic

pictures are not just supplements to the text – they also complement and complete
the meanings suggested by the written text. You may roughly categories visuals as
either images (pictures that depict some real world situation typically captured by a
camera), or graphics (pictures drawn or painted that depict any fictitious scenario)
(Parekh, 2006).
      According to Boots Liquigan (2016), visual information is not merely an added
feature to the written text to make it more sensible and more appealing to readers
like you, it has its own distinct features that enhance your information acquisition.
                                            3
      Visual information may take the form of photographs, visual aids, and other
displays that use pictures to convey idea. Visuals may either be images or graphics.
In the aspect of learning, visual information may be useful because of the features
and functions of pictorial messages with respect to printed tex. In visual information
storage, compression is a consideration because the information might not be
dramatically affected in terms of size, resolution, and ease of retrieval and sharing.
                What’s New
Activity 1: Pictorial Essay
      Instructions: In the space below, create a pictorial essay on any topic you
have in mind. Ask a classmate to retell your pictorial essay and validate or refute
your classmate’s version of the essay.
       When you were growing up, you may remember yourself enjoying reading
some materials with lots of pictures that accompany the written text. More often than
not, the number of pictures in a page of a printed material can probably be the deal-
maker or deal-breaker for you to even bother reading the entirely of that material.
This goes to show how pictures can really be worth “a thousand words”.

                What is It
VISUAL INFORMATION AND MEDIA
     VISUAL MEDIA                             VISUAL INFORMATION
EXAMPLE OF VISUAL MEDIA
    - Photography
    - Video
    - Screenshots
    - Infographics
    - Data Visualization (Charts and Graphs)
    - Comic Strips / Cartoons
    - Memes
    - Visual Note-Taking
Visual media are images or frames of images that we can construct and reconstruct
to give different meaning to it. We can observe it with photographs, videos,
infographics comics, memes and other objects that projects an image.
What is an image?
       An image is a type of visual information that you normally see as either “pure
black and white or grayscale having a number of gray shades or color containing a
number of color shades.” In images, color is everything. Color, in technical terms,
refers to the sensation generated to the eyes of the beholder due to differences
in frequencies. You may remember from your physics class that when light passes
through a spectrum, lower frequencies produce the reddish hue, while the higher
frequencies produce the bluish ones. In visual arts, you may consider black as the
presence of all colors if color is to be considered as a pigment. If color is explained
in terms of principles of light, then white is the combination of all the colors.
Color as Primary Attribute of Images
      Color is what gives form to an image. You are able to appreciate an image
because of how the colors blend to create the image.
      You discern the color of an object because when light hits an object, the object
may absorb some color components of the light while it reflects those with
frequencies specific to our eye. Color models, which are used to recognize and
communicate color information, define a set of colors. The two most common ones
                                          5
are the RGB color model and the CMYK color model. The RGB is used for colored
lights like images on a monitor screen and has the colors red, green, and blue as its
primary colors. The CMYK is used for colored inks like images printed on paper and
has the colors cyan, magenta, yellow, and black as the primary colors. The two
models are considered to be device dependent because they depend on the physical
properties of the devices which generate the colors from these models.

      Another alternative color model is HSB Model which stands for Hue,
Saturation and Brightness. This color model is device dependent.
      Hue - specific tone of color),
      Saturation - the intensity of a hue from gray tone to pure, vivid color, and
      Brightness - the relative lightness or darkness of a particular color.
      Remember that is it not always possible to convert a color accurately form one
model to another because each model has its own range of colors.
                                         6
Stage of Image Generation
                                                          An image undergoes a
                                                      process     when     it     is
                                                      generated. The conversion
                                                      of a paper image into an
                                                      electronic one is part of the
                                                      input stage which involves
                                                      the use of an image
                                                      scanner. The scanner has
                                                      sensors that capture and
                                                      convert each portion of an
                                                      image     being    scanned.
                                                      These portions are turned
                                                      into pixels, and are stored
                                                      digitally in a computer.
                                                      Another way an image may
        Source: http://www.getloupe.com/v/9dg1bo8k   be produced is a digital
                                                     camera, a gadget you are
most familiar with since mobile phones these days have built-in digital cameras.
Much like a scanner, a digital camera also has electronic sensors called Charge-
Couple Devices (CCD).
       Editing is a stage where the digital image is manipulated with the use of
editing software. Editing involves “operations like selecting, copying, scaling,
rotating, trimming, changing the brightness, contrast, color tones, etc. of an image
to transform it as per the requirements of the application.”
       When the image has already been edited, it may be stored in a file format that
can be displayed on the computer screen or in printed form. Storing or saving the
image will require compressing the file into a size that will not take much of computer
storage memory. There is a variety of file formats that may be used in storing images.
Few other concerns on image storage include resolution and overall quality of the
image.
What Are Graphics
        Pictures that are either drawn by the hand or through computer software are
called graphics. When you sketch or draw an image such as a chart or a drawing
that may resemble an image, you create a pictorial representation of an idea or object.
When you do so, you create a graphic.
        If you become a graphic artist, you will be acquainted with two types of a
digitally produced graphic. These are raster graphics and vector graphics. The Raster
Graphics is much like an image especially when a drawing is digitized using a
scanner and the Vector Graphic, on the other hand, is produced through computer
software; thus, it is already in digital form. Vector graphics are typically stored in
smaller file sizes, and can be scaled without compromising the quality of the drawing.
                                          7
Software is used to edit the appearance of the graphic, enabling into an animation
especially in multimedia presentation (Parekh, 2006)
Graphics as Used in Learning or Instruction
      Visual information is especially useful in learning. According to Clark and
Lyons (2011), graphic has Three Functions in this aspect of your use for such visual
information.
       1. Surface Features – These refer to the salient features of visuals; and
          often, they suggest that “a series of still visuals can be more effective
          for some learning goals such as teaching how things work (Mayer,
          Sims, and Tajika (2005), as cited in Clark and Lyons, 2011)

      2. Communication Function. Graphics have the communication
         purpose to show motion or represent illustrate quantitative
         relationships. The table below, you will see how a graphic may
         communicate certain ideas.

3. Cognitive Psychological Functions – Graphics also serve such functionality by
illustrating the interaction of visuals with” human learning processes such as
attention or retrieval from memory”.
Uses of Graphics
      Learners like you are more responsive to ideas because of both the denotative
capacity and connotative power of visual images and representation (Liquigan, 2016).
Web sites or multimedia output normally makes use of graphics to build user
                                          9
interface. A graphic can become the clickable item such as a browser menu, button,
tab, or window.
        In automated offices, graphics are used (especially for desktop publishing) to
represent data in charts, tables, graphs, and other data presentation tools. Also,
fields that require designs or drawings heavily use graphics for 2D or 3D modeling
of such designs. Simulators and animators also use graphics for their animation,
simulation, and other related applications. Even artworks and decorations utilize
graphics. In media such as film and television, graphics are typically used to design
program title or banners, advertisements, and visual effects.
The File Format, Lossy Compression, and Lossless Compression
File Format – The key consideration in the selection of a particular format for storing
visual media is compression. This is because you may not want to reduce or
compromise the quality of your data especially when you want to store them in
smaller file sizes so that they may be retrieved or downloaded easily. As has been
mentioned earlier, color is everything. So Reducing the file size will also affect the
color quality of visual information.
Lossy Compression – When you are amenable to reducing the quality of the image
or graphic due to reduction of the file size, you are opting for a lossy kind of
compression. The image or graphics may have a lower resolution but would still keep
the appearance of the visual since you may not be too sensitive with the color change.
Lossless Compression – A more accurate way of storing the visual information is
through lossless compression because it does not allow the image to dramatically
lose its appearance. This still is an efficient manner of compressing since it. “look(s)
for a recurring pattern in the file, and replace (s) each occurrence with a short
abbreviation, thereby cutting the file size. (www.users.wfu.edu).”
                         Common Visual Media File Type
    Type                                          Description
 TIFF (Tagged       -     a very flexible format that can be lossless or lossy.
 Image    File      -     details of the image storage algorithm are included as part of the
 Format                   file.
                      - used almost exclusively as a lossless image storage format that
                          uses no compression at all.
                      - Sometimes a lossless compression algorithm called LZW is used,
                          but it is not universally supported.
 PNG             Is also a lossless storage format. However, in contrast with common
 (Portable       TIFF usage, it looks for patterns in the image that it can use to compress
 Network         file size. The compression is exactly reversible, so the image is recovered
 Graphics        exactly.
 GIF (Graphic    Creates a table of up to 256 colors from a pool of 16 million. If the
 Interchange     image has fewer than 256 colors, GIF can render the image
 Format          exactly. When the image contains many colors, software that creates
                                            10
                 the GIF uses any of several algorithms to approximate the colors in the
                 image with the limited palette of 256 colors available. Better algorithms
                 search the image to find an optimum set of 256 colors. Sometimes GIF
                 uses the nearest color to represent each pixel, and sometimes it uses
                 "error diffusion" to adjust the color of nearby pixels to correct for the
                 error in each pixel.
                 GIF achieves compression in two ways. First, it reduces the number
                 of colors of color-rich images, thereby reducing the number of bits
                 needed per pixel, as just described. Second, it replaces commonly
                 occurring patterns (especially large areas of uniform color) with a short
                 abbreviation: instead of storing "white, white, white, white, white," it
                 stores "5 white."
 JPG ( Joint     PG is optimized for photographs and similar continuous tone
 Photographic    images that contain many, many colors. It can achieve astounding
 Experts         compression ratios even while maintaining very high image
 Group)          quality. GIF compression is unkind to such images. JPG works by
                 analyzing images and discarding kinds of information that the
                 eye is least likely to notice. It stores information as 24 bit color.
                 Important: the degree of compression of JPG is adjustable. At
                 moderate compression levels of photographic images, it is very difficult
                 for the eye to discern any difference from the original, even at extreme
                 magnification. Compression factors of more than 20 are often quite
                 acceptable. Better graphics programs, such as Paintshop Pro and
                 Photoshop, allow you to view the image quality and file size as a function
                 of compression level, so that you can conveniently choose the balance
                 between quality and file size.
 RAW             RAW is an image output option available on better digital cameras.
                 Though lossless, it is a factor of three of four smaller than TIFF files of
                 the same image. The disadvantage is that there is a different RAW
                 format for each manufacturer, and so you may have to use the
                 manufacturer's software to view the images. (Some graphics
                 applications can read some manufacturer's RAW formats.)
 BMP             BMP is an uncompressed proprietary format invented by Microsoft.
 (Bitmap)        There is really no reason to ever use this format.
 PSD             are proprietary formats used by graphics programs. Photoshop's
 (Photoshop      files have the PSD extension, while Paint Shop Pro files use PSP or
 Document)       PSPimage. These are the preferred working formats as you edit
 or PSP (Paint   images in the software, because only the proprietary formats retain
 Shop Pro)       all the editing power of the programs. These packages use layers, for
                 example, to build complex images, and layer information may be lost
                 in the nonproprietary formats such as TIFF and JPG. However, be
                 sure to save your end result as a standard TIFF or JPG, or you may
                 not be able to view it in a few years when your software has changed.

       Currently, GIF, PNG, and JPG are the formats used for nearly all web images.
TIFF is not widely supported by web browsers, and should be avoided for web use.
PNG does everything GIF does, and better, so is increasingly replacing GIF. PNG will
not replace JPG, since JPG is capable of much greater compression of photographic
images, even when set for quite minimal loss of quality.

Advantages and Disadvantage of Visual Media
      Visual information is useful for a variety of reasons. A visual aid is helpful to
present information to illiterate audiences. It can also stimulate oral communication
since people may still need to explain the data that is contained in a visual
presentation such as graphs, charts, and tablets.
       Presenting information visually is an easy way to relay information because it
makes use of universal cues or signs that people are familiar with. Complex
information is presented graphically which makes it easier for people to interpret the
message. As has been said over and over, pictures are worth a thousand words, and
thus they have an impact on the people’s understanding of ideas, regardless of who
and where they are. Visual information also saves times in relaying the message. The
use of visual information also enhances resourcefulness and creativity.
       In the journalist practice, visual information is very useful in the quick
presentation of facts, in the emphasis of points in the printed text, and in conveying
the information to the readers.
       But using visual information may also be very limiting because of the cost of
the preparation, the complexity of certain images and graphics, and the lack of
familiarity of the audience to some cues and signs conveyed by the visual
information. The latter concerned may be due to the ambiguity of the visual
information or he multiple meanings that a single visual can suggest to different
audiences.
