6th April 2017 – Ian Harris
I recently used one of our VMD360 Latent Fingerprint Development systems to carry out an experiment in order to develop a mark on a sample of leather from a luggage label holder. I placed a natural mark on the leather and the next day developed the mark using Stirling Silver as the evaporated metal in the VMD process.
The images below were taken in our lab with no additional lighting and photographed using a phone camera. I am sure with additional lighting and a good camera further ridge detail would be seen. The next step is to do the same with the addition of Zinc to improve contrast.
