Illustrations By Tiago Hoisel

The American "golden age of illustration" lasted from the 1880s until shortly after World War I (although the active career of several later "golden age" illustrators went on for another few decades). As in Europe a few decades earlier, newspapers, mass market magazines, and illustrated books had become the dominant media of public consumption. Improvements in printing technology freed illustrators to experiment with color and new rendering techniques. A small group of illustrators in this time became rich and famous. The imagery they created was a portrait of American aspirations of the time.
Technical illustration
Technical illustration is the use of illustration to visually communicate information of a technical nature. Technical illustrations can be component technical drawings or diagrams. Technical illustration in general aim "to generate expressive images that effectively convey certain information via the visual channel to the human observer". Nowadays, many illustration programs are used to create technical illustrations due the need for detailed imaging and repeated updating. Besides the commonplace 2-D Adobe Illustrator, there are many 3-D computer graphics software that are often utilized to create illustration for textbooks, especially scientific ones.
