OnePlus' latest flagship, the OnePlus 8 Pro, is inarguably the company's best smartphone yet. Unlike its predecessors, the OnePlus 8 Pro (review) is a full-fledged flagship device that packs in all of the features that the company skimped out on in previous generations. These include things like support for fast wireless charging, an IP rating for dust/water resistance, and a flagship-grade camera setup. Speaking of which, the OnePlus 8 Pro packs in a quad-camera setup like most other premium flagships out there. However, OnePlus' choice of camera sensors doesn't fall in line with the current trend in the premium flagship space. Instead of using a 108MP Samsung ISOCELL sensor or a 64MP Sony IMX686 sensor, the OnePlus 8 Pro packs in a 48MP Sony IMX689 primary sensor. The primary camera is accompanied by a 48MP ultra-wide sensor, an 8MP telephoto camera, and a new 5MP Color Filter camera; the likes of which we haven't seen in any other smartphone out there.

OnePlus claims that the Color Filter camera is used for camera filters that can be applied to the final shot but that can also be achieved even without the Color Filter camera. This means that the sensor can only be used for infrared photography, using the new Photochrom mode on the OnePlus 8 Pro. However, as it turns out, there's another use case for the new Color Filter camera. According to a recent post from XDA Senior Member combat goofwing on our forums, the sensor can be used to see through some plastic objects.

As you can see in the images above, clicking pictures of some plastic objects using the Color Filter camera in the Photochrom mode reveals their internal circuitry. While we aren't completely sure of the reason behind this behavior, it seems that the Color Filter camera is not filtering IR light as there is no IR cutoff filter which, in turn, allows you to see through the plastic. As demonstrated in a video shared on the original thread, the 'feature' works even in the viewfinder and you can clearly see the internal circuitry of a TV remote. Max Weinbach from our team was able to test the feature on his OnePlus 8 Pro and it seems to work on a vast variety of objects, ranging from security cameras to VR headsets (gallery). And no, this can't be used to see through clothes. Don't try it, perverts.
