A lot of AI deepfake photos, especially of people, have an electronic sheen to them, “an aesthetic sort of smoothing effect” that leaves skin “looking incredibly polished,” Ajder said.He warned, however, that creative prompting can sometimes eliminate this and many other signs of AI manipulation.Check the consistency of shadows and lighting. Often the subject is in clear focus and appears convincingly lifelike but elements in the backdrop might not be so realistic or polished.LOOK AT THE FACESFace-swapping is one of the most common deepfake methods. Experts advise looking closely at the edges of the face. Does the facial skin tone match the rest of the head or the body? Are the edges of the face sharp or blurry?If you suspect video of a person speaking has been doctored, look at their mouth. Do their lip movements match the audio perfectly?Ajder suggests looking at the teeth. Are they clear, or are they blurry and somehow not consistent with how they look in real life?Cybersecurity company Norton says algorithms might not be sophisticated enough yet to generate individual teeth, so a lack of outlines for individual teeth could be a clue.THINK ABOUT THE BIGGER PICTURESometimes the context matters. Take a beat to consider whether what you’re seeing is plausible.The Poynter journalism website advises that if you see a public figure doing something that seems “exaggerated, unrealistic or not in character,” it could be a deepfake.For example, would the pope really be wearing a luxury puffer jacket, as depicted by a notorious fake photo? If he did, wouldn’t there be additional photos or videos published by legitimate sources?
