Photo Tampering Throughout History\n\nPhotography lost its innocence many years ago. In as early as the 1860s, photographs were already being manipulated, only a few decades after Niepce created the first photograph in 1814. With the advent of high-resolution digital cameras, powerful personal computers and sophisticated photo-editing software, the manipulation of digital images is becoming more common. Here, I have collected some examples of tampering throughout history.\n\nTo help contend with the implications of this tampering, we have developed a series of tools for detecting traces of tampering in digital images (contact me at Ma'at Consulting for more information about our services).
Long before the first public announcements of photographic processes in 1839, Joseph Nicéphore Niépce, a scientifically-minded gentleman living on his country estate near Chalon-sur-Saône, France, began experimenting with photography. Fascinated with the craze for the newly-invented art of lithography which swept over France in 1813, he began his initial experiments by 1816. Unable to draw well, Niépce first placed engravings, made transparent, onto engraving stones or glass plates coated with a light-sensitive varnish of his own composition. These experiments, together with his application of the then-popular optical instrument, the camera obscura, would eventually lead him to the invention of the new medium.
