Techopedia explains Fauxtography
The term fauxtography may have emerged in 2006 when freelance photographer Adnan Hajj provided an altered photograph of what was described as an Israeli raid in Beirut. Reuters printed the photo, and it quickly spread online. However, the billowing black smoke was later discovered to have been digitally added, along with other elements of the photo. Fauxtography is especially dangerous in photojournalism because audiences trust the news to provide accurate representations of worldwide events. When images are photoshopped or staged, this can drastically change how people feel about the event depicted.
