Focusing in the photographic archive of Julián Carrillo (México), a microstructural analysis of surface photography was carried on to prove the feasibility of atomic force microscopy to identify the binder used in the manufactured ancient photography. It has been identified 2 structural groups in which known binders may be classified, one of them is associated with gelatin and the other one to albumen and collodion. The former group present a higher roughness values than the second one, being able to identify the binder by means of its morphology aspect related with the width of linear traces. From the obtained results, it has been observed that atomic force microscopy is a very good technique to properly identify the binder used in a photograph according to the surface morphology and roughness values.
