procédés

Procédés is the plural of the French noun procédé, meaning methods, processes, or procedures used to achieve a result. It is employed across a broad range of domains to denote distinct techniques applied to transform materials, perform tasks, or produce outcomes. In English, the closest equivalents are method, process, technique, or procedure, though the French plural often conveys a set of practical techniques within a field.

Etymology and scope: Procédé derives from the verb procéder (to proceed), which in turn comes from Latin procedere. The term has long been used in technical and artistic contexts. In contemporary French, procédé mainly refers to a specific technique or way of doing something within a discipline; for formal legal or administrative steps, the word procédure is more common.

Applications: In science and industry, les procédés describe manufacturing or transformation routes, such as heating, distillation, electroplating, polymerization, or fermentation. In chemistry and chemical engineering, process design often hinges on optimizing one or more procédés for efficiency, yield, or environmental impact. In photography and printing, the expression procédés photographiques refers to historical image-making methods, for example the daguerréotype procedure, calotype, collodion process, or gum printing.

Usage and translation: The term is predominantly used in French-language texts and technical literature. In English-language writing, it is typically translated as process, technique, or method, depending on context. When discussing historical or artisanal practices, it may be rendered as “photographic procédés” or “industrial procédés,” retaining the French term to reflect specificity in technique.
