NEGATIVES IN PHOTOGRAPHIC COLLECTIONS – HISTORY, IDENTIFICATION, PROCESSING AND PRESERVATION
Hrvoje Gržina
Sažetak
Photographs stored in archives, museums, libraries or private collections illustrate wide range of historical photographic procedures and techniques. From the very beginning these procedures and techniques had followed the development of technologies and were changing in accordance with them, so that we can now distinguish around one hundred and fifty different procedures and techniques used in the preparation of photographs. Amongst them, a special place belongs to the photographic negatives which capture many interesting images of visual age, including historical events, people, scientific evidence, and works of art. Negatives are present in photography since the earliest days of Fox Talbot's first attempts. Being unique images from the camera they always have the value of the original from which it is subsequently possible to make positives or copies in analog or digital form. The fact that negatives are created directly in the camera means that they contain the highest quality information, and that each successive generation will have a certain percentage of information loss whether it is positive or copied negative. Unfortunately, in the past, negatives had been approached as something that was only leading towards the final product, with no permanent value, and were often neglected, poorly stored or destroyed. For these reasons, although it is of great importance to preserve the original negatives from degradation,
it won't be possible without basic knowledge about the nature of object. Thus, the precise identification and a set of actions related to the organization and preservation of photographic collections become an essential issue for which every archivist or curator of photographic collections should have an answer, to assure the longevity of the valuable objects from pre-digital age of photography
for future generations.
