Bleus de travail (2002–2003) explores vocational training environments as part of a broader collection of student portraits taken across several technical schools. The series is divided into subsets: student welders, boilermakers, industrial maintenance technicians, mechanics, agricultural mechanics, paper industry technicians, horticulturists, farmers, florists, roofers, carpenters, joiners, cabinetmakers, masons, plumbers, painters, stonemasons, bakers and pastry chefs, and finally butchers. It serves as a true catalog of workwear, photographed in training spaces. From attire to surroundings, everything is designed to protect inexperienced trainees as they learn their trade.
