Study (fingerprint on wall..)

STUDY: Latent Fingerprint Development on the non-porous surface at a different time intervals

The present study was conducted to develop latent fingerprints on the non-porous surface at different time intervals by using the revolutionary invention Forenscope 4K Tablet Systems

During this examination, no fingerprint powders or chemicals were applied to the surface before or after imaging. Only a handprint was applied on the surface and the handprint and fingerprint were checked with Forenscope 4K systems.

Test surface: Water-based matt white paint (The most common type)

This case is aimed at how the latent fingerprints on the wall will be searched and displayed under UVA light without laser 254nm UVC. Fingerprint searching without using a laser or 254 nm UVC light source. Fingerprint searching with UVC light sources and Laser lights are a significant health and safety issue for the crime scene investigator due to radiation being transmitted through the air and quartz but absorbed by ordinary glass. However, Protective clothing should be worn before using UVC light as it protects the entire body, not just the eyes.

Important Note: ForenScope 4K Software Images can be saved in RAW or BMP, and videos in RAW or MP4 format. You can simply convert images into JPG or PNG format and Videos into AVI format with an internal converter in the software.
