Write a 17 pages paper on fingerprint photographic technique for recover of marks. In general, we have three types of fingerprints mainly latent, plastic and latent prints. Latent prints are formed from oils and sweat from the skin surface. They are invisible to the unaided eye, therefore. they require additional treatments. Patent fingerprints are made from ink, grease, dirt and blood. They are visible to the naked eye. Finally, the plastic fingerprints are in three-dimension, and they are made after pressing the hands-on fresh soap, wax or paints. The prints are visible to the naked eye (Houck and Siegel, 2010, p. 29).
To improve the visibility of latent fingerprints various lighting techniques can be used to obtain the invisible surfaces. According to Chaikovsky, Argaman, Batman, Sin-David, Barzovski and Yaalon (2005, p. 574), digital multiple exposure technique is applied. The process is simple and productive. Digital photography and computerized image processing with the application of layers methodology produce many images that are easily controlled by computer programmes. Production of many images that are combined into a single image enables improved visualization of the selected portions of the latent print without affecting the rest part of the image.
According to SIRCHIE (2013, p. 1), Crime scene photos are important in the crime scene inquiry. The photographs complement the investigator data in the form of data. A camera can be used to capture every object of importance within the crime scene.
Warren (2014, p. 1), conducted research to determine the usage of digital photography for forensic purposes. It was found out that digital imaging devices with spectral filters are very effective in the identification of untreated latent fingerprints in that it is viable and non-destructive.
