The evolution of the different cyanoacrylates, now manufactured specifically for latent print development, as well as the introductions of a wide variety of fuming chambers, have induced a false belief that one only needs to push the Start button in order to achieve the best possible results. The reaction also stabilizes the ridge detail to better preserve for possible future enhancement (through use of fingerprint powder at the scene or by use of dye stains back at the Lab) and collection at a scene or in the Laboratory.The images below show a surface bearing latent prints as viewed with ambient light (left), with side lighting (center) and with ambient light after cyanoacrylate fuming (right).
