However, it seems the process relies on the phone’s infrared sensors, which collect a type of radiation that’s invisible to the human eye. There’s a great video from Unbox Therapy (below) which shows the filter in action, looking through an Apple TV box, a Switch remote, and even a thin black T-Shirt.īut how does it work? We reached out to OnePlus to see what they know, but the company declined to comment. Ben first saw this trick via Ben Geskin on Twitter (above) but lots of people have since demonstrated it. Think things like TV remotes rather than the sturdier plastic of a high-end DSLR. It only works on very thin black plastic that’s already a little see-through in the right light. If you’ve got a OnePlus 8 Pro and want to try it out for yourself, just open up the camera app, swipe over to the “Photochrom” color filter, and point it some black objects.įair warning: we experimented with the filter ourselves and it really is quite selective. It’s a feature of the new OnePlus 8 Pro, which seems to use the phone’s infrared sensors to see through a small subset of black materials. Or, at least, something that looks very much like it. Well, here’s a camera trick we’ve not seen in a smartphone before: X-ray vision.
