Résumé
Paper conservators often take pictures of their objects before and after treatment. Macro-pictures in particular are useful tomonitorcolourchanges, removal ofmaterial, or ink diffusion possibly occurring on a millimetre scale. Their reliability however strongly depends on lighting reproducibility, which is not easy to achieve with conventional light booths. These are usually too large to appropriately monitor small-scale lighting. An alternative was found in a small light booth initially designed for machine vision lighting systems and capable to insure a good reproducibility of the light on a centimetre scale
