Porous fingerprint evidence received into the laboratory is typically treated with reagents specific to the constituents of the latent fingermark reside (amino acids). These chemicals, Ninhydrin, 1,2-Indanedione and 1,8-Diazafluoren-9-one, for example, produce both visible (ninhydrin) and invisible (1,2-IND and DFO) reaction products that all require time-consuming imaging considerations, to obtain usable results. Fluorescence imaging, in particular, is oftentimes extremely time consuming, given the initial necessity to screen evidence for friction ridge detail, prior to marking up and final documentable photography.This workshop will seek to help attendees understand the most effective techniques that will facilitate optimization of results and efficient evidence workflow. Light theory will be reviewed to illustrate the interactions between illumination and viewing wavelengths in order to effectively photograph these differing chemical treatments. Attendees will study and utilize ‘conventional’ imaging methods for porous evidence types, before being introduced to a novel process that will undoubtedly increase operational efficiencies and excellence for these often encountered, volume pieces of evidence.
