Dedication of Designs

First and foremost, what is a design? A design is a a plan or drawing produced to show the look and function or workings of a building, garment, or other object before it is built or made. Design is something affects our daily world but it’s safe to say that it’s not really noticeable to us unless it’s something that’s not appealing or “bad”. Don Norman who is the author of The Design of Everyday Things is concerned how things work, how they are controlled and the nature of interaction between people and technology. Don Norman also points out that good designs is actually a lot harder to notice than poor designs because good designs fits our needs so well that the design is invisible, serving us without drawing attention to it’s self. When it comes to designs, sight is our most powerful sense. Most of us take that for granted a certain level of visual ability. Let’s talk about visual disabilities. Some people who have visual disabilities that aren’t easily corrected and some have no vision at all. According to Webaim, Legal blindness" is when the best corrected visual acuity is 20/200, or less, or the person's visual field is 20 degrees or less. Visual acuity of 20/200 means the person must stand 20 feet away to see something that can be seen from 200 feet away by someone with 20/20 vision. People who are blind have an array of assistive technologies available to support common tasks, such as using the web.” There is also something called color blindness and color vision deficiency. It is a fascinating topic because of its complexity. The human eye has three types of photoreceptors, each of which is responsible for detecting different color wavelengths. Additionally, photoreceptors called rods detect light



intensity. Color-blindness can occur if any of these types of photoreceptors is missing or functioning incorrectly.

Importance of Photographs & Visuals

Image
         How important is a photograph and visual? That is the main question in today’s day and age where we live in a time of social media and heavy technology usage. They say a picture is worth a thousand words, and it definitely is. Photography was developed with a heavy appeal in Western Europe and the U.S in the 19th century. Photojournalism began to develop right after newspapers found a way to get visuals in their readings. Because of this, photography became the stories and had a heavy influence to certain events. Looking at a picture is still very much different than watching a movie or show on television because when you look at a visual that doesn’t move, it gives you time to react, feel emotions, and think about the visual. Photography plays a role in freezing time for the viewer because while it is a still photo, it gives you time to look at the picture in terms of the way its sculpted, what’s going on in the image and looking in depth within the photo.           Let’s tal

Typography: The Importance

Image
When we think of letters, do we just think about that it's apart of a word or do we see it as a form of art? Letters have become invisible to the fact that they're not just objects that are used in words, but rather as a form of art to represent the sounds, words, and information that we speak on which is a type of communication; verbal. In order to interpret these visuals in our brains and process them with their sounds, we have to understand what they represent. In essence, typography is the art of arranging letters and text in a way that makes the copy legible, clear, and visually appealing to the reader. Typography involves font style, appearance, and structure, which aims to elicit certain emotions and convey specific messages. Typography is what brings the text to life. Typography is so much more than just choosing beautiful fonts: it’s a vital component of user interface design .

The Intro: What is Visual Communication?

        Let’s start this post off with one question: How is visual communication expressed as form of communication? Using our verbal communication is a way to express ourselves and shows symbolism. When we use our verbal language, we use our voice, tempo, and loudness to show how much our words to mean to us. The word denotation means when we look at the dictionary for a word, and take that how it is. Even though we do this, there is more to the word than the basic dictionary definition. We use these words to help us express ourself, emotions, relate to stories, attitudes, not to just use the world strictly how it looks to us. When we hear of visual communication, we think its based on an expressive basis but words actually play a huge role in helping us communicate through visual communication. On the other hand, there is also connotation. Connotation is the implied meanings, emotions and associations also expanding and repositioning the denotative meaning. When using connotation, it
