How to Lift Fingerprints: Dusting For Prints
Вставка
- Опубліковано 19 жов 2017
- I show how to lift fingerprints by using a brush and powder. The brush I use is a zephyr fiberglass fingerprint brush and the powder is lightning powder which is a black latent fingerprint powder. Fingerprint patterns and characteristics are formed before birth. They will remain unchanged until decomposition destroys them after death, or unless the dermal layer is injured, producing a scar. Our fingers have friction ridges which are composed of rows of sweat pores, or eccrine glands, that constantly secrete perspiration. This perspiration along with grease and oil transferred from other parts of the body adheres to the friction skin and is transferred from the skin to other surfaces when contact is made with objects. The transferred outline of the friction ridges is what is known as a latent print.

What I used:
- Zephyr Brush: amzn.to/3qbbr9z
- Lightning Powder: amzn.to/3o8TN4j
- Ultra Clear Tape: amzn.to/37jHWty
- Fingerprint Cards: amzn.to/3qinLEG
Latent prints are not readily visible to the naked eye and must be developed in some way to increase their visibility and contrast. The method I show in this video is to physically enhance the latent prints by applying fingerprint powder. Fingerprint powder is composed of many different ingredients that can vary greatly depending on the formula used. Most black fingerprint powders contain rosin, black ferric oxide and lampblack. Many also contain inorganic chemicals such as lead, mercury, cadmium, copper, silicon, titanium and bismuth. Fingerprint powder is applied by brushing it onto the surface and works by mechanically adhering to the oil and moisture components of the latent print. When the powder particles adhere to the grease or moisture forming the latent prints, it causes them to become visible. The developed latent prints are then readily observable and able to be collected, preserved and examined.

I have to do this because of my online school
Yo me 2!!
But it was a bit hard
same for my forensics thing
In forensic science at school we got to try the magnetic powder method and it was my favourite method
Hi do you have Instagram I have some questions
I love the cat cameos at the end.
Fingerprints are on the ledge which posiedon tries to get to but he can't because the prints are on the ball
😂 thanks guys really appreciate it
Interesting
Nicely done. Can I purchase an affordable finger print kit on line?
Try Amazon.
When not doing this professionally but on a DIY basis, once the prints are extracted what is the best way to store the print? I.e can you recommend any computer software that print photos can be uploaded to and be stored?
Make a file, and use some paper to attach the tape to it. Name them. A computer...? Never thought of it.
You can photograph the evidence to store it as a TIF or JPG (mind the compression rates) at a high resolution (1000 dpi or higher), but the actual evidence is the print itself. When lifting the print with proper fingerprint lifting tape (not shown or discussed in this video) and put on a lift card (again specifically designed for the task and not discussed in this video) then the evidence is secured/retained for decades.
Where can you find a device that have a fingerprint examiner??
Dot: I found Prince!
Yakko: No, no, no, fingerprints.
Dot: ...I dont think so.
ur a prince boi
Wheres th evideo?
Criminal: touches surface
Police: :D

Hi does anyone know what are the different forensic brushes? :( Badly need help
Normal brush. And the magnetic brush
Yes because we all understand this
What is the best way make homemade finger print powder???
make ur own
@@ninjaboykawesome6105 how!?

Many people like to use flour, although that can’t be stored for a long time. I like to shave chalk pastels although the grains are slightly bigger but it’s a start!
Name of background music during the first few minutes?
Use shazam
