The Collection of Photographs is a collection of documentary photographs which holds 13.000 photographs (black and white and in colour), slides, negatives and several thousand of digital records, all of them divided into several thematic groups. These are: Croatian museums and galleries (buildings, permanent exhibitions, exhibitions, museum objects, activities…), the MDC (history and activities), museums and their holdings in the war, collectors (portraits and settings), church collections and inventories (architecture and objects), educational activities in museums, international holdings (including material that relates to museums from the former Yugoslavia).

The materials for the Collection of photographs have been systematically collected ever since MDC was founded – during field visits, work on MDC projects, professional trips and through donations.

The holdings date from the early 1930s to the present day. The material includes not only photographs taken by MDC staff, but also by authors like Branko Balić, Antun Bauer, Marija Braut, Zvonimir Buljević, Boris Cvjetanović, Tošo Dabac, Damir Fabijanić, Mladen Grčević, Đuro Griesbach, Miljenko Smokvina, Šime Strikoman, Josip Špralja, Krešimir Tadić, Pavo Urban, Milisav Vesović and Jozo Vranić.
