The illustrations were crafted by mixing real photography on set and postproduction in CGI, at a level you can’t tell where one ends and where the other starts. First, professional food photographer were taken on set, so they stablished the mood and the scenery to mimic high-end restaurateur images. Then, to model the “bacteria ads” the art directors, 3D artists, and modelers took real medical bacteria illustrations as a reference, achieving a hyper-realistic result that camouflages the bacteria in the plate and the kitchen photos flawlessly.
