'Of course, that doesn't tell you that the image was manipulated, but … maybe that should give you pause.' 'When you edit an image, it adds its own little bit of metadata,' Dr Farid said.
This includes the make of the camera, time of day the photo was snapped and GPS coordinates, if that's enabled.īetter yet, if the image was opened in Photoshop and re-saved, it will tell you that too. 'There are many websites where you can upload an image and it will strip out the metadata and show it to you,' Dr Farid said. Next, try burrowing into its metadata - the swathe of information that's added to the photo by the camera. So a photo has passed the reverse image search. If an image has been recirculated from another website, or repurposed for whatever disaster has most recently struck, they can be discovered with a reverse image search.īetter yet, you might find the image debunked on or another outlet. 'Images of sharks are almost always fake.' 'Every time there's a natural disaster, people circulate the same silly images of sharks swimming down the street,' Dr Farid said. When he sees an image pop up on Twitter or Facebook, Dr Farid likes to see if it's been on the internet before by doing a reverse image search, using Google Images or TinEye.
