“Seeing is no longer believing in our modern digital world. Powerful photo-manipulation software is available to anyone who seeks it. And according to digital forensics expert Hany Farid, improved forging technologies make it more important now than ever to look at photographs with a discerning eye. We asked Farid to scrutinize several photographs of NOVA scienceNOW host Neil deGrasse Tyson with different celebrities and then determine which were forgeries that we created. ..Try your hand at differentiating doctored from untouched photos (acknowledging, of course, that Farid likely had a lot more technology and experience at his disposal than you do).”
