00:00I'm a forensic officer here at the Ballarat Forensic Hub.
00:03Today I'll be showing some demonstrations of some common techniques that we use here
00:08in forensics. Fingerprint powders are widely used across
00:12forensics, out of crime scenes, within the laboratory. We've got a variety of different
00:17types. Here I'm using a white fingerprint powder. We base our fingerprint powders on
00:23our surface type and our color of our background. We have a range of light sources that we can use.
00:29We can use our natural ambient light, we can use our white light just like a torch,
00:35or we have the capability here at the Hub to do poly lights or poly flares.
00:40These are all different wavelengths in light and it really helps us enhance our fingerprints.
00:45We also have a range of reagents that we can use to enhance our fingerprints
00:50on a porous type surface. So anything like paper, cardboard,
00:56magazines, you know that semi-porous as well. We have a range of reagents that will enhance that
01:02using different light sources. In particular, this chemical I am using today, I will be
01:08pouring our reagent over the top, letting it dry, placing it into the oven,
01:13heating it up. We'll then visualize it under certain wavelengths.
01:18And this reagent in particular is a highly fluorescent, gives this highly fluorescent detail.
