There are two different types of image-editing software available for users. The most basic type is a raster-based program, which allows users to work with a photo using pixels, which are small units that make up the image. Pixels basically serve as pieces to the puzzle; once all of the pieces are in place, the picture is complete.The other type of image-editing software is a vector-based program. Vector-based programs are more mathematically based, allowing users to employ the use of lines and geometrical shapes to achieve an illustration. There are many different image-editing programs to choose from, varying from vector-based to raster-based and freeware to software that needs to be purchased for a fee before use. A few examples include GIMP (GNU Image Manipulation Program), which is a freeware raster-based program that offers the ability to edit, retouch, and even animate images; Cotrel Painter which is a raster-based program that strives to mimic the characteristics of real-life art like drawing and painting, and Miniscope, a freeware vector-based program that has most of the same tools and features of GIMP. A professional designer having freeware programs at his/her finger tips can be beneficial, as these types of programs provide a wide variety of useful photo-editing tools without the hefty fee of purchasing a copy of a program. Ultimately, the money can be put towards other relative costs, such as photography equipment, a website promoting the designer's work, or even business cards.
What are the pros and cons of each image type (raster vs. vector)?
