Ultraviolet and Infrared Digital Photography. Ultraviolet (UV) and infrared (IR) photography are important tools in forensic analysis. Cameras that are capable of recording UV and IR light can be used for a variety of purposes such as the enhancement of bloodstain patterns, gunshot residue patterns, and fingerprint evidence on surfaces that normally do not provide much constrast using only. Forensics investigators use infrared photography to see things in a crime scene that are invisible to the eye. TNO, an independent research organization, conducted tests on a sample crime scene in February 2010. They compared a regular photograph to an infrared photograph taken at the same time and found some interesting results Forensic photography regularly represents the paramount method to collect and preserve evidence in forensic cases including forensic odontology. Modern technology enables the investigator to obtain photographs using wavelengths of the light spectrum that are normally obscured from vision. The use of ALI, UV, normal, and IR light source.

SDFI's Contrast Forensic Camera System is designed to be used with Contrast Lights. Contrast Lights are lights that shine more Ultraviolet light than normal or more Infrared Light than normal. People are only able to see a very limited range of light without help, mostly between 400nm and about 700nm. Contrast Photography offers. Digital Ultraviolet and Infrared Photography discusses the growing number of applications of ultraviolet and infrared photography. Scientific and technical photographers, such as those engaged in scientific, medical, forensic, and landscape and wildlife photography routinely use ultraviolet and infrared techniques, and these techniques are growing in use in creative photography Abstract. UV light provides more detail and contrast to an injured area, including bite marks, than standard lighting techniques. There are two techniques for UV photography. In one method, known as reflective UV imaging, the wound is flooded with UV light, and the reflected UV image is photographed. An UV bandpass filter mounted on the camera. Usually, in forensic sciences, ultraviolet (UV) light is used to induce fluorescence on many samples to identify and evaluate proofs (ex. fibers, gunshot residue, biologic fluids, pigments, inks and fingerprints) and different wavelength are used to better enhance the material characteristics Recapturing a five-month-old bite mark by means of reflective ultraviolet photography.

Documentation of skin wounds via still photography and dynamic video photographic techniques, which utilize various methods of UV illumination, are covered. Techniques important for courtroom presentation of evidence gathered from lacerations, contusions, abrasions, and bite marks are presented through case studies and controlled experiments There are two types of photography that can be done with UV lighting for forensic purposes. The first type is UV reflectography (UVR). With UVR, you are simply illuminating a work with UV light and photographing the resulting image with a camera using a UV lens filter Forensic UV has been in use for years because UV light will cause organic and other chemical compounds to fluoresce. Fluorescence is a reaction to UV light where a substance absorbs the UV photons, atoms in the substance are excited, and then they emit a photon of a longer wavelength—typically in the visible spectrum Ultraviolet photography is an interesting photographic method of capturing images by using light from the ultraviolet spectrum. Photographs captured in this way can have an artistic purpose but they can also be used in dermatology or forensics because ultraviolet images reveal deterioration and damages of various structures (such as skin) not apparent under visible light

Abstract. Usually, in forensic sciences, ultraviolet (UV) light is used to induce fluorescence on many samples to identify and evaluate proofs (ex. fibers, gunshot residue, biologic fluids, pigments, inks and fingerprints) and different wavelength are used to better enhance the material characteristics UV photography is very different from the photography of UV-excited fluorescence in the visible range. Fluorescence is the emission of longer wavelengths than those of incident light. Thus, illumination with UV radiation can cause the subject to fluoresce by emitting visible light

Out of all light sources, UV and IR are the significant sources of radiation that are widely used in the majority of the Questioned Document examination. Ultraviolet (UV) is a 10 nm to 400 nm wavelength electromagnetic radiation that is shorter than visible light but longer than X-rays. UV radiation is found in sunlight and contributes about 10.

Written by Harry Parsons. With procedural dramas like Law and Order and CSI glamorizing police work, many people feel drawn to the lives of those individuals who dedicate themselves to solving crimes. For those with an artistic leaning, forensic photography represents the melding. Therefore, when using the UV-105 for conventional visible photography, particularly when at high altitude locations, Company Seven recommends use of an optional UV blocking filter such as the Nikon L37c 52mm to prevent a blue blur cast from appearing across the image. A side benefit is the protection of the lens front element when this. Bruising is one of the most common types of soft tissue injury noted on victims of violence, including intimate partner violence, sexual assault, child abuse, and vulnerable adult abuse 1-4.Such injuries are usually caused by blunt, compressive or squeezing force trauma resulting in damaged blood vessels 5, 6.Evidence of bruising is usually identified by forensic clinicians through observed. Forensic photographers may be sworn police personnel (especially in smaller departments) or they may be full-time forensic scientists. Visual records gathered using photography are used to prosecute criminal cases and are subject to the same rules of evidence and chain of custody requirements as any other evidence
