When you're starting up a business, having a professional image is essential. With all the different formats, options and file types it's easy to get a bit confused about what to use and when.
The two main types of digital image are 'raster' and 'vector'.
Vector images are made up of points, lines and curves or 'paths' and are completely scalable without losing image quality. Software packages such as Adobe Illustrator or Corel Draw are available and used by most professional studios.
Raster images, also referred to as 'bitmap' and 'pixel' images are made up of a vast amount of tiny squares, called pixels. Raster images aren't scaleable in the same way as vectors, and will distort and blur if they're stretched too far.
