NOVA interviewed Hany Farid, the world's leading digital forensics expert. If you want to know if an image is real or fake, he's the guy to ask. To accompany the interview, they posted a nine image real-or-fake challenge
. Each image shows NOVA host Neil deGrasse Tyson posing with a different celebrity. You have to figure out which images are fake, and which are real. Farid then gives the answer in an audio clip and explains what clues you should have looked for.
It's a good quiz. I got one wrong. But on a few of them I guessed and got lucky.
