Using Photoshop and Illustrator software, GRA-220 is an introduction to professional computer graphics creation and to the software and hardware typically used in the graphic design, video, photography, and interactive web/multimedia industries. Emphasis is placed on the professional use of image-capturing devices such as scanners, digital cameras, and video cameras. Image editing and color management systems are discussed and demonstrated, along with the important differences between vector and bitmap graphics and preparing images for print, broadcast, and web distribution.
Distribution medium determines image preparation
The course covers how significantly image preparation differs depending on the final distribution medium — print, broadcast, or web — since each medium has genuinely different technical requirements for resolution, color, and format.
Ethical standards for digital imagery
GRA-220 explicitly addresses copyright issues pertaining to digital imagery, treating ethical industry standards as a core professional competency alongside technical image creation skill.
Key topics in GRA220
- Professional image-capturing devices

Our writers help with GRA-220 introduction to digital imaging assignments and image preparation projects.
Worked example: distribution medium changing preparation needs
- Web-optimized image: Compressed file size, RGB color, lower resolution for fast loading
- Print-ready image: Much higher resolution, CMYK color, larger file size for quality printing
- Lesson: GRA-220 teaches that the same source image requires genuinely different preparation depending on its final distribution medium, not a one-size-fits-all approach

Frequently asked questions
Each distribution medium has genuinely different technical requirements — print requires much higher resolution and CMYK color mode for accurate physical reproduction, while web images need compression and RGB color for fast loading and screen display — and an image prepared correctly for one medium can look poor or fail to work correctly in another. GRA-220 covers this because professional digital imaging work requires understanding these genuine technical differences, not treating all image output as interchangeable.
Digital imaging professionals regularly work with images sourced from various places, and using copyrighted material improperly can create real legal and professional consequences for both the designer and their client or employer, meaning ethical and legal awareness around image sourcing is a genuine, practical professional competency, not a separate legal specialty. GRA-220 includes this because responsible digital imaging practice requires this ethical awareness alongside technical skill, not technical competency alone.
