In a brief introduction, this guide identifies some of the career opportunities open to competent airbrush artists and indicates the most frequent users (technical illustrators, photo retouchers, commercial artists and designers) of the airbrush technique. The guide includes objectives for teaching airbrush, equipment and materials needed, preparation of projects, procedure for setting up equipment, the air brush process, cleaning and maintenance of equipment, and graphic illustrations of common errors with causes and remedies identified. Nine suggested rendering projects, which list each project's objectives and procedures, cover a major portion of the guide. The appendix offers sources for supplementary reading, a list of airbrush manufacturers, and possible sources for equipment and supplies. (HD)
