Can you match a photo to the discrete camera it was taken with, without metadata?

Over on Quora, a user asks the following question: "Are there enough digital and/or analog difference in individual cameras/houses/lenses that photos will have fingerprint of sorts? When, or in what circumstance could a photograph be linked not only to a lens/house model or manufacturer but to one specific camera, distinguished from any other camera of the same model?" Essentially, can you

The Impact of Surveillance on the Practice of Law

Here's an interesting article on the impact of surveillance. "...

Have politics and personalities influenced decisions in police controlled labs?

I recently received a head's up about an open letter written by an LE commander for whom I used to work. This letter has stirred up some strong emotions and heated comments.

Marketing vs. news you can use

This month, I received a renewal notice for Evidence Technology Magazine. It went straight into the trash. Why? It's not really about cutting edge technology from the standpoint of learning a technique that can add value to your workday - at least from a DME Forensics standpoint. It's a marketing device for manufacturers to get their tools shown in a positive light. I should know, I've written

One line of thinking is that Photoshop is extensible. If there's something
