- Latent fingerprint photography normally requires the use of various lighting techniques to capture those difficult surfaces on which latents are discovered. One such technique, is the digital multiple exposure technique which is considered simple and productive, using digital photography and computerized image processing using layers methodology. This technique …
Fluorescence Photography of Latent Fingerprints: Using …
- https://www.ojp.gov/ncjrs/virtual-library/abstracts/fluorescence-photography-latent-fingerprints-using-electronic-flash
- Abstract. A popular technique for locating fingerprints is the use of fluorescent powder and a blue excitation filter attached to a flashlight with an orange viewing/barrier filter. Use of a blue excitation filter with an electronic flash involves attaching the blue filter directly to the flash and holding the orange viewing/barrier filter over the camera lens.

- Latent print card showing original location of fingerprint. (Staggs,2021) Direct lighting: It is a strong lighting that comes directly from a source rather than being reflected off another surface. This lighting technique provides a great contrast between the light and dark parts of the object being photographed. 2 or 4 lights are balanced and aligned 45 degrees …

- Photographing Latent Prints Latent prints should be photographed with a 35mm SLR camera or a high resolution (10 mega pixel or greater) digital SLR camera Cameras must have close-up photography capabilities. Recommended film speed for 35mm is 100 ISO or slower. For digital images, use the largest file format available. Digital images should be captured in .tiff or RAW file

- Determining the identity of the owners of latent prints is often key to crime scene research, such as the owner of this latent printed pulled from a fingernail file. A NIST test shows that emerging software that automates the extraction of distinguishing features from latent prints is more advanced than expected.

- Most prints you can see, such as on glass. However, if the prints are less noticeable, you can dust for prints. Step 2: Test the Lighting . Next is illuminating prints well. The most effective way to ensure your lighting works is by looking at lighting from several different angles. Pick the one you can see fingerprints the best in.
An investigation of latent fingerprinting techniques

- Latent fingerprint upliftment from different surfaces is the first step in the processing of latent fingerprints. Since different surfaces possess different properties (texture, porosity, etc.), we require different techniques for latent fingerprint upliftment which are discussed in Table 1. This is the most vital step among all the preprocessing steps because …
