Quebec artist Ulric Collette has an ongoing series of portraits that combine the images of two related people who have been told they look alike. These Genetic Portraits fuse the two faces side-by-side. Collette blends the hair and clothing in a way that makes them look natural. The picture above is of Ginette, who was 61 at the time, and her granddaughter Ismaëlle, who was 12. Despite the age difference, they have a remarkable family resemblance. Below is Kristof and his mother Madineg.
People always ask Collette to blend their family pictures, but he explains that he must take the portraits himself to get the orientation, the lighting, and the expression just right. Here is the artist himself, on the right, with his cousin Justine.
Bored Panda has a ranked list of 30 of Collette's genetic portraits. See more of his work at Instagram.
