Definition of "graphic design" from the dictionary: "The practice or profession of designing print or electronic forms of visual information, as for an advertisement, publication, or website." Graphic design uses skills such as photography, typography, and other types of art form to create pieces of displays or brochures, posters, logos, and letterheads in the advertising industry and others. Many graphic designers use different types of programs depending on the field they specialize in, but the most popular programs used nowadays are Adobe Photoshop, and 'In Design'. If the designer were looking forward to creating 3D graphics, first they would use Adobe Photoshop and Illustrator to create the 2D design. Then, they would use Macromedia Extreme 3D to create the 3D elements. The last step would be to import it into Macromedia Director .

Here are some basic rules of graphic designs:

Color Rules:

Use contrasting colors for readability
Dark text on a light background is easy to read. It goes without saying that dark text on a dark background, or light text on a light background, is difficult to read. You need to make sure that there's enough contrast between your text and background for the text to be readable.
Light text on a dark background is also easy to read, but it should be used sparingly. It's more tiring to the eyes to read large amounts of text on a dark background.
Use color sparingly.
You choose to design in more than one color for one reason: for impact. If color is thrown around everywhere, it loses its impact. Make sure that you use color for maximum impact for headings, or even the most important words in headings.
Do not use complementary colors. Complementary colors are colors that are opposite each other on the color wheel, such as blue and orange. When these two colors are used side by side, the eye has trouble focusing on both at the same time, and the colors may actually seem to vibrate.

Image Design Rules:
Use graphic devices such as white space, rules, and images. Pull quotes, large initial caps, decorative caps, and dingbats (a decorative typographic character) to help the reader understand the content. Remember that a picture is worth a thousand words. Perhaps not, but a dynamic image that supports the copy certainly clarifies what you are trying to say. Keep the style of imagery consistent. It is all right to mix line art, photography, and painterly images, but make sure that the feel of each image complements the other images.
