Workshop Presented by Derek Hardy - Arrowhead Forensics

This workshop is an overview of UV/IR forensic photography from shortwave ultraviolet (254nm) through real infrared (1100nm). UV-IR is invisible to the naked eye and only specific cameras are equipped to view and capture these wavelengths. UV/IR photography removes backgrounds and creates a contrast between the surface and evidence allowing the user to see invisible evidence!

UV/IR cameras can capture: untreated fingerprints on porous and non-porous surfaces, curved surfaces, fumed fingerprints, dye-stained latent prints, blood, urine, saliva, semen, questioned documents, gun-shot-residue, reflective surfaces, foot impressions and more. High resolution imaging sensors equipped in the highest graded UV/IR cameras not only will capture in all wavelengths, but the images produced are up to 4,300 pixels per inch, exceeding the AFIS latent print submission requirement. Also, learn how varied spectrum wavelength light sources, coupled with the correct barrier filters, fluoresce and reveal different types of evidence.
