Streszczenie
The quality of a fingerprint is, of course, very important for both serching in the Automated Fingerprint Information System (AFIS) anf for the comparison with prints of a suspected person. We know, from past experience, that very thin and hardly visible prints often contain more detail and iformation than we initialy expect. Photographing these types of prints to recover the maximum detail has traditionally required high tech methods and cameras with expensive bellows systems. It would not be possible to photograph prints of these types with good detail using a standard camera or a digital camera. We have developed a new photographic technique that captures excellent detail. This new method involves a casting technique, projected light and a transparent mirror. This method has provited excellent results, particularly in cases involving CNA developed fingerprints and fingerprints in blood. The method can be used with a standard camera and also with a digital camera for the AFIS system.
