Why do conservators document treatments with photographs and written reports?

In the field of art conservation and restoration, professional conservators document treatments with photographs and written reports because art conservation has become an essential tool of research.

These records serve as a vital account of the work performed on an object, ensuring that future conservators understand the history of any interventions. This practice is closely tied to the modern principle of reversibility, which dictates that any treatment applied to an artwork should not cause permanent alteration to the original piece. By maintaining detailed documentation, professionals can track the condition of the work and the methods used to preserve or repair it, upholding the integrity of the object for the future.1
