The paper aimed to acquaint a reader with the concept of photography, the most important photographic techniques and their specificities, and with its application in the conservation and restoration profession as a method of research in the form of photographic documentation. Knowledge of the different light sources (such as normal illumination, side and specular illumination, transmissive illumination, low-angle illumination, and photography with polarized filters) can play an important role in shooting museum objects. Light sources can be used to illuminate an object, which is important because that is the only way to highlight object surface details, texture and shape, which is crucial for quality photo documentation. Photo documentation is an important segment of the conservation and restoration profession since it provides one of the most effective and frequent pictorial notes in heritage documentation. Moreover, the paper explains special shots and specific scientific methods - a methodological exploration of details that are invisible to the naked eye, using UV and IR artwork photography. Such examination of the artwork can provide useful information and conclusions regarding the object under study, such as analysis and detection of underlining, sub-layers of color, forgeries, etc.
