There are two main ways to edit an image, although there are numerous ways to actually carry out the process. For the sake of unity, we’ll look at the processes used in the Adobe Photoshop program, with particular emphasis on the Illustrator application. Although there are numerous other methods and programs available, Illustrator is one of the most popular and among the easiest to use.

The two methods of editing we shall look at are rasterizing an image and vectorizing your graphics. The fundamental difference between the two is that a vectorized image is one that is converted to line-based graphics, while a rasterized image is made up of dots and pixels. The method you choose depends upon personal taste to an extent and how you plan to use the image.
A vectorized image is much sharper and cleaner than a rasterized one, with visibly less blurring upon enlargement. It’s a crisp image that can be expanded without affecting textures and imperfections. The downside to vectorization is that the process is slightly longer and more complicated than rasterization. Illustrator produces a great vectorized image, but doesn’t pick up lighter colors easily and requires further editing.
A rasterized image is constructed through pixels and is perfect for use in 3D programs and for web pages. Although the resulting graphics are easy to produce in less than 10 steps with Illustrator, they aren’t as sharp as vectorized images upon closer inspection and don’t expand or enlarge as well.
Whether you’re creating a webpage or art, there are pros and cons for both methods. The best way to decide which method is best for you really does depend on how you plan to use the image.
