Introduction

The technology that can distort and manipulate digital media is developing at break-neck speeds, and it is imperative that the technology that can detect such alterations develop just as quickly. The field of photo forensics seeks to restore some trust to photography.
At their foundation, photo forensic techniques rely on understanding and modeling the imaging pipeline, from the interaction of light with the physical 3-D world, the refraction of light as it passes through the camera lenses, the transformation of light to electrical signals in the camera sensor, and, finally, the conversion of electrical signals into a digital image file. This set of lectures focuses on the first part of the imaging pipeline, so-called physics-based techniques.

Hi Hany,
I greatly enjoyed this overview. If you're already familiar, I'm curious about your thoughts on programs like InVID and WeVerify. I've been thinking about the black box comment you made in reference to the world of online citizen journalism. Services like those mentioned carry a potential public harm as a result of the software's accessibilty when used by users with common knowledge gaps. I'm thinking about this in the same way that users of Eliza fell prey to Banel Deception, as argued by Simone Natlale in the book Deceptive Media.
I wonder whether the currently accelerated public fascination with the engaging with OSINT will facilitate an eviorment where foresic practitioners' expertise is routinely contested.
Thanks for your thoughts. I look forward to the rest of this playlist!
