New innovations in crime scene photography and surveillance photography enhance forensic collection of visual information used in the investigation of incidences. Whether used to document evidence at the scene of a crime or autopsies photography contributes to the body of discovery in a case.
Surveillance photography innovation in Luminol ultraviolet or infrared imaging has greatly enhanced the investigation of bodily evidence (i.e. blood, hair, skin etc.).
Innovations in other areas of photography now enhance crime scene photography capabilities in: accident reconstruction, aerial viewing, ballistics, biological, fire investigation, microphotography, photomicrography and photomicrography, photogrammetry, radiography, time lapse, high speed, underwater and videography constitute the range of technological engagement applied in law enforcement forensics.
More modest innovation in digital photography has also advanced the telephoto lens shoots in speed of development and repository for record. Charged coupled devices (CCD) and complementary metal oxide semi-conductor (CMOS) computer chips disseminate imagery by way of thousands of pixels on each shot.
Pixel transmission is conducted via electrical charge. Conversion by circuits in the camera create the digitized image. Advantage of immediacy is the benefit. Digital screens also reduce errors. Authenticity is an issue as digital imagery is readily altered. Admissibility in court is on a case-by-case basis.
Digital photography bodes well for forensics record management. Internet service providers’ have made it possible for photographers to load images by way of internet service, CLEAR internet (online website), wireless internet or 4G internet. Forensic photographers may also upload crime scene pics to an Online Website.
Newer digital cameras use Smart Card data storage. While there is some variation in Smart Card capacity, memory is generally far larger than that of a standard disc or the internal memory of the camera. Smart Cards offers more in terms of rapid data collection and storage, as well as data transfer of larger records.
