This article investigates the role that scientific portraits play in shaping public perceptions of scientists and, by extension, the scientific enterprise. A new category of scientific portrait, termed the “scientist at work,” is introduced and discussed through the lens of Perelman and Olbrechts-Tyteca’s theories about creating value and presence for an audience.

The International Science and Engineering Visualization Challenge, recently established by the National Science Foundation (NSF), is an alleged attempt at public outreach. The NSF encourages scientists to submit visualizations that would appeal to non-expert audiences by displaying their work in an annual “special feature” in Science magazine, and each year they present the winning image on the cover of Science as the ultimate reward. Although the NSF advertizes the competition as an attempt to educate non-scientists, the visualizations lack sufficient textual explanation in the Science special feature articles and do not demonstrate clear significance for current issues in science. This article assesses the actual motivations behind the NSF's “Visualization Challenge,” given the lack of accompanying textual information, and it explores the consequences of allowing “scientific” visualizations to float into the public sphere unexplained. It will be shown that the spirit of this competition exemplifies the current shift from “public understanding of science” to “public appreciation of science” in the growing field of Science Communication, particularly through the technique of “framing” devices. This shift in objective, accentuated in the realm of visual communication, reinforces the public's view of science as a mythic authority.
