The collection counts several thousand photos and negatives from the mid-nineteenth century. to the present day. Criteria for collecting photos and postcards are quality, techniques of making and documentary. Most are black and white and brown toned photos, while postcards are equally represented in black and white, brown, gray and green tones and colors. The themes can be categorized into the political, military, economic, educational, sports and cultural history of Rijeka and its immediate surroundings. Apart from the portraits of men, women and children, and group portraits of class, military, celebration and political gatherings, are also filmed outdoor motifs, city panorama, city portions, public buildings and scenes from everyday life. Massive shooting outside of the studio has taken a big impact with the appearance of the first postcards, illustrated travel guides, and brochures. Some of the foreign photographic studios in Rijeka collaborated with domestic postcards publishers for which they filmed custom motifs.
One of the most valuable specimens kept in the fundraiser of the collection is the dagerotypia of 1848 (Unknown author, Anton and Alfred Von Vallentsits, 10.2×7.3 cm). Daguerobius was born in Vienna at the time of Revolution and resistance to Metternich.
