The museum’s collection consists mainly of equipment and materials from the period between the end of the 18th and the early 21st century.
One can see, amongst other exhibits, lithophanes, polioramas, chambre clair, viewers from the two decades 1840-1860 (including the first original Brewster stereoscope), the German camera "Stirn" from 1888 - one of the first spy cameras, as well as many micro and spy-cameras also on display - and different rural models of the late 19th century with their original tripod. It also chronicles the history of Leica equipment in the history of worldwide photography, with the display of all the models from before and after the war.
The collection also includes the cameras used in worldwide conflicts including the Murer, which the Italian army used in World War I, and a rare example that the Japanese used at Pearl Harbour.
In the collection all types of printing are represented, from the first photo to digital: daguerreotypes, wet collodion, ferrotypes, gelatin paper, autochrome, glass plates and albumin, etc.
There is also a section, which documents history and traditions since 1840, showing old photographs of Sulmona from collections of noble families and famous people who have lived and worked in the city.
