Some artists draw with their left hand and some with their right, but Dutch artist Rajacenna van Dam manages photo-like accuracy drawing with both simultaneously.

“I can go faster and it’s also less boring,” she says of her ambidextrous artistry.

It has also been a success, with views piling up on a YouTube time-lapse video of the 25-year-old artist drawing singer Taylor Swift and actress Selena Gomez simultaneously.

Her most photo-like portraits in coloured pencil take roughly 40 hours to complete.

As she draws, her eyes focus on one hand, then the other, as she moves from one picture to the other. She began drawing seriously with coloured pencils and gel pens at age 16, inspired by an Italian street artist.
