	Graphic type	Describe how the graphic is constructed and why you chose the graphic type	How will the final file be saved?
Internet graphic	Bitmap	When a photo is taken on a Digital camera or when an image is scanned from a magazine a bitmap graphic is created. A bitmap is made out of tiny parts these are called pixels, they usually come in all different colours. You can edit a bitmap and also edit every individual pixel. This is because a computer has stored information about every pixel in the image. A bitmap graphic is usually quite large. However when you change the size of a bitmap graphic the image becomes distorted meaning the graphic loses quality.	Jpeg, Gif or Png
Van sign graphic	Vector	A Vector graphic is created in graphic packages. But unlike bitmap they consist of shapes called objects. You can edit each object individually by shape size and colour. Even though a vector can be quite large it does not need much memory to be stored. Therefore the file size of a vector is usually small. They are also scalable meaning when you change the size of them they do not lose quality.	EPS, AL, PDF, SVG or DXF
Brochure	Writing-Vector Pictures-Bitmap	You would use both vector and bitmap. Bitmap for pictures because you would want them to look more lifelike. Whereas a vector would be better for writing because it will stay clear making it easier to read.	PDF
