On the system of selection and reassembling of the photographic records in relation to the aims of a company Bigazzi said: “[Photographs] are far from being independent and objective testimonies of companies’ vicissitudes. In fact, they seem to be more reluctant than written records to give us the information we seek. First of all, we must not underestimate the selection process of industrial photography. The first stage immediately follows the production and consists of deciding which images are most effective for advertising a product, illustrating commemorative volumes, showing the stages of manufacturing on technical prints, and so on. These images have a different future: some of them are used only once, while others are used in more than one occasion. Sometimes they become symbols, and remain so even after the product or the stage of production they depict becomes obsolete; there are other cases in which images created with a specific aim, after a few years become symbols. The symbols of the company express the values that the company wishes to embed in time, even when there are changes in the technical procedures or the organization.” D.
