OnePlus has begun rolling out the 220.127.116.11 update for its flagships OnePlus 9 and OnePlus 9 Pro. The new firmware adds a camera mode called XPan.
XPan mode is a reference to the Hasselblad XPan, an updated version of the Fuji TX-1 dual-format camera released in the late 90s. Its main feature was the ability to shoot not only on 35mm film, but also in a wider format of 65mm for panoramas with an aspect ratio of 65:24 (or 2.7: 1).
The XPan mode in the OnePlus 9 series simulates shooting with this camera. When activated, the screen launches a new interface with a 65:25 aspect ratio viewfinder and limited controls. You only have the option to switch between two color modes: a slightly modified natural color preset and a default black and white mode based on Ilford Delta 400 film. You can also switch the focal length from 45mm to a wider 30mm, which means switching to an ultra wide angle lens …
Since the 65:25 aspect ratio on a smartphone cannot be recreated natively, images are cropped using the native 4: 3 sensor. The irony is that the original XPan created panoramas by actually enlarging the field of view rather than clipping or masking the standard one. The result is a 20MP image with a resolution of 7872 × 2916 (45 mm) and 7552 × 2798 (30 mm). However, XPan mode can only be used in landscape orientation.
But keep in mind that after shooting, the final image is slowly formed and stored. According to the manufacturer, this “reproduces the ritual meaning of the film’s manifestation.” It also takes almost 4.5 seconds before you can take another shot. So this is definitely a rush mode.
OnePlus is also offering some camera performance improvements in this update. In addition, the firmware includes the September security patch.
