One of the fundamental topics within graphic design, format represents the physical point of contact with the user.
Basics Design 01: Format examines established format standards and demonstrates how a creative approach to format selection and presentation space can produce dramatic results in both print and digital media. New material in this edition includes a new chapter, focusing on on-screen, online and moving image, and much of the content has been updated and restructured.
