Vector Graphics

Unlike JPEGs, GIFs, and BMP images, vector graphics are not made up of a grid of pixels. Instead, vector graphics are comprised of paths, which are defined by a start and end point, along with other points, curves, and angles along the way. A path can be a line, a square, a triangle, or a curvy shape. These paths can be used to create simple drawings or complex diagrams. Paths are even used to define the characters of specific typefaces.
Because vector-based images are not made up of a specific number of dots, they can be scaled to a larger size and not lose any image quality. If you blow up a raster graphic (made up of a grid of pixels), it will look blocky, or "pixelated." When you blow up a vector graphic, the edges of each object within the graphic stay smooth and clean. This makes vector graphics ideal for logos, which can be small enough to appear on a business card, but can also be scaled to fill a billboard.

This is a website I am going to use to help me work my way around Illustrator in order to produce a vector graphic for the CD/DVD in my digipak. Vector Graphics commonly consist of bright colours and are usually very vibrant, used more for R'n'B style music album covers. However, with the alteration of the colours I hope to make a graphic to suit the genre of my album. I can also do this by make the graphic itself very simplistic and something that can represent the artist as an independent artist- making it a logo.

Existing Vector Graphics:

I could take on a more relaxed, funny childish feel to it in which it will address a specific type of audience and present the personality of my artist in a fun way. However, I feel it may not fit well with the genre and/or other images on the album.

I could produce a similar vector to this and, instead, use it as the back image of the album. In doing this, I can create the exact amount of space I want/need for text and I feel a simple design will fit well with genre. If I do this, though I will have to create one of a similar style for the rest of the album in order to show continuity. This is something I may look more into.



These are some images I found of vector graphics used on existing album covers.
I could create a single logo to be featured on my album cover, however since my artist is independent it would be more conventional to have a photograph of her or I could create a vector based on her as an individual.
