A few issues. First, ALWAYS wear gloves when processing for latent fingerprints. Second, way too much powder being used at the start. Over-processing can destroy the evidence by contaminating the surface to the degree that the developed print can not be distinguished from the remaining area. Also, I want to stress the importance of writing on the acetate IMMEDIATELY after placing the tape, to assure the orientation is viewed correctly by the fingerprint examiner. Opaque cards are commonly used in the USA instead of a transparent sheet for this reason.

We start at the top to remove the excess. NO, you put too much powder on the brush you dipped in the pot. Shake the pot and use the very small amount on he lid to use for dusting, and spin the brush to remove excess.

can any1 tell after 1 month of a crime can we take offender 's fingerprints for forensic test?is it helpful ?

asim khawaja the "freshness" of fingerprints can not be determined once they are on a surface. It is true that on a non-porous surface, the residues are mostly water and will evaporate to some degree, but the remaining residues may often be re-hydrated as part of the processing.

can this work for paw prints? I want to know if a coyote came into my yard in the middle of the night. I found paw prints bigger than my Lab and I have 2 smaller dogs and just want to figure out which animal they were left by.

Over powdered. How much Aluminium powder do you need to take fingerprints? Not that much! :-O I'm actually shocked, those fingerprints were over powdered! Load your brush by a slight spin on the rim of the container! You could probably do a better job with baby powder :-O

+Sezla L He was just giving a quick demonstration to show us how is works. If that was a real murder investigation though, the evidence could have been ruined.

This is in very little detail and many contamination and mistakes may occur. There is so much more to be done while doing this technique. Feels like 4 years gap had influenced the way fingerprints are being taken. But still it reminded me well of what I have actually done :D.

How much powder? Obviously not an operational CSI!
Matthew Keisling

Gary Currie this video shows WAY too much powder. If the presenter hadn't already known the location of the impressions, and they were actually at the top of the window, all that excess powder would have eliminated any contrast between the developed print and the surrounding surface. Start with a tiny amount. You can always add more. Cleaning away excess powder isn't always possible, especially on a dirty or contaminated surface.

Good basics, but a bit gash. The main reason for the mask is to stop breathing in the aluminium powder. If DNA is required from a subject, this should be carefully swabbed first, no powder should go anywhere near it, as this can 'kill off' any DNA! A diagram needs to go on the acetate or Foil as he called it. Finally, each end of the tape should be cut with a scalpel and over signed by a CSI or CSI and witness, in Scotland. Still a pretty good video, though.
