There are essentially two types of graphics. They are raster graphics and vector graphics. Raster graphics are composed of small dots called pixels. Raster graphics are also known as bitmapped graphics. A pixel is the smallest element of a picture. It usually a square with a shade of color. Together, millons of pixels help form a picture. In 2004, cell phone cameras were 1 mega pixel. This means that pictures taken by a phone in 2004 would have consisted of 1 million pixels. Todays phones, however, have cameras that are 14 mega pixels. Each picture has 14 million pixels. This allows cameras to produce high definition pictures and videos.

One of the difference between raster and vector graphics is that raster graphics consist of many dots called pixels that form a picture. Vector graphics, on the other hand, are made of lines and form a smooth image. When raster images are enlarged, they begin to fade away and the quality of the picture drops. Vector images, however, can be enlarged and the quality of the picture remains the same.

Nintendo Games are examples of raster graphics. Most of the environments, in the games, and characters were made of pixels.

A vector is made out of lines. This produces a much more crisper and smooth picture.

An Image editor lets you add special effects to your pictures. Movie studios, on the other hand, use graphics to enhance their story lines and create action scenes that would be nearly impossible to do without graphics.
