Photo forensics
Photographs have been doctored since photography was invented. Dictators have erased people from photographs and from history. Politicians have manipulated photos for short-term political gain. Altering photographs in the predigital era required time-consuming darkroom work. Today, powerful and low-cost digital technology makes it relatively easy to alter digital images, and the resulting fakes are difficult to detect. The field of photo forensics - pioneered in Hany Farid's lab at Dartmouth College - restores some trust to photography. In this book, Farid describes techniques that can be used to authenticate photos.
