Image analysis
Visual communication contains image aspects. The interpretation of images is subjective and to understand the depth of meaning, or multiple meanings, communicated in an image requires image analysis. Images can be analyzed though many perspectives, for example these six major perspectives presented by Paul Martin Lester: Personal, Historical, Technical, Ethical, Cultural, and Critical.


 * Personal perspective: When a viewer has an opinion about an image based on their personal thoughts. Personal response depends on the viewer's thoughts and values, individually. However, this might sometimes conflict with cultural values. Also when a viewer has viewed an image with a personal perspective, it is hard to change the view of the image on the viewer, even though the image can be seen in other ways.
 * Historical perspective: An image's view can be arising from the history of the use of media. Through times sort images have been changed, because the use of different (new) media. For example: The result of using the computer to edit images (e.g. Photoshop) is quite different when comparing images that are made and edited by craft.
 * Technical perspective: When the view of an image is influenced by the use of lights, position and the presentation of the image. The right use of light, position and presentation of the image can improve the view of the image. It makes the image looks better than the reality.
 * Ethical perspective: From this perspective, the maker of the image, the viewer and the image itself must be responsible morally and ethically to the image. This perspective is also categorized in six categories: categorical imperative, utilitarianism, hedonism, golden mean, golden rule, and veil of ignorance.
 * Cultural perspective: Symbolization is an important definition for this perspective. Cultural perspective involves identity of symbols. The uses of words that are related with the image, the use of heroes in the image, etc. are the symbolization of the image. The cultural perspective can also be seen as the semiotic perspective.
 * Critical perspective: The view of images in the critical perspective is when the viewers criticize the images, but the critics have been made in interests of the society, although an individual makes the critics. This way this perspective differs from the personal perspective.

Visual aid media: Simple to advanced
Visual aids can play an important part in your level of communication as well as improve how you come across towards your audience. Visual aids can help engage your audience, enhance their level of understanding of the presentation, cause an emotional response and allow for the convention of important subject material. Additionally, they can give shape and form to your words and thoughts, helping with the audiences understanding of the topic.


 * Chalkboard or whiteboard: Chalkboards and whiteboards are very useful visual aids, particularly when more advanced types of media are available. They are cheap and also allow for much flexibility. The use of chalkboards or whiteboards is convenient, but they are not a perfect visual aid. Often, using this medium as an aid can create confusion or boredom. Particularly if a student who is not familiar with how to properly use visual aids attempts to draw on a board while they are speaking, they detract time and attention from their actual speech.
 * Poster board: A poster is a very simple and easy visual aid. Posters can display charts, graphs, pictures, or illustrations. The biggest drawback of using a poster as a visual aid is that often a poster can appear unprofessional. Since a poster board paper is relatively flimsy, often the paper will bend or fall over. The best way to present a poster is to hang it up or tape it to a wall.
 * Handouts: Handouts can also display charts, graphs, pictures, or illustrations. An important aspect of the use of a handout is that a person can keep a handout with them long after the presentation is over. This can help the person better remember what was discussed. Passing out handouts, however, can be extremely distracting. Once a handout is given out, it might potentially be difficult to bring back your audience's attention. The person who receives the handout might be tempted to read what is on the paper, which will keep them from listening to what the speaker is saying. If using a handout, the speaker distributes the hand out right before you reference it. Distributing handouts is acceptable in a lecture that is an hour or two, but in a short lecture of five to ten minutes, a handout should not be used.
 * Video excerpts: A video can be a great visual aid and attention grabber, however, a video is not a replacement for an actual speech. There are several potential drawbacks to playing a video during a speech or lecture. First, if a video is playing that includes audio, the speaker will not be able to talk. Also, if the video is very exciting and interesting, it can make what the speaker is saying appear boring and uninteresting. The key to showing a video during a presentation is to make sure to transition smoothly into the video and to only show very short clips.
 * Projection equipment: There are several types of projectors. These include slide projectors, overhead projectors, and computer projectors. Slide projectors are the oldest form of projector, and are no longer used. Overhead projectors are still used but are somewhat inconvenient to use. In order to use an overhead projector, a transparency must be made of whatever is being projected onto the screen. This takes time and costs money. Computer projectors are the most technologically advanced projectors. When using a computer projector, pictures and slides are easily taken right from a computer either online or from a saved file and are blown up and shown on a large screen. Though computer projectors are technologically advanced, they are not always completely reliable because technological breakdowns are not uncommon of the computers of today.
 * Computer-assisted presentations: Presentations through presentation software can be an extremely useful visual aid, especially for longer presentations. For five- to ten-minute presentations, it is probably not worth the time or effort to put together a deck of slides. For longer presentations, however, they can be a great way to keep the audience engaged and keep the speaker on track. A potential drawback of using them is that it usually takes a lot of time and energy to put together. There is also the possibility of a computer malfunction, which can mess up the flow of a presentation.
