This raises the question of the balance to be respected between artistic sensitivity and scientific rigour. A scientific illustration depends largely on the (scientific) context in which it is produced and, as a result, can represent content that is true at a given moment and false at t+1 with the constant evolution of knowledge. Nevertheless, the primary purpose of a scientific image remains to convey a scientific truth. But to do this, artistic skills are required in order to convey the most attractive message possible. Despite the expansion of technologies such as photography and digital drawing, it is above all the illustrator's talents and mastery of his/her/their tools that dictate the quality of the final result. The artist therefore uses his creativity and infuses his productions with what some call his 'aura'. From this idea stems the slogan that 'an image is never neutral', but rather results - in the case of scientific illustrations - from a compromise between scientific objectivity and the illustrator's (cultural) profile, which together shape the illustration itself, and by extension, shape its interpretation.
