iPhone 14 Pro IR Laser

IPhone IR laser

Camera: Leica SL2-S
Exposure: 1/13
Aperture: f/1.4
Focal Length: 35mm
ISO: 6,400

I discovered something rather interesting when playing with the new iPhone 14 facial recognition and the Leica SL2-S.  Apparently the SL2-S is exquisitely sensitive to the IR laser energy from the iPhone.  I don’t know yet if this is true with other cameras or not as different cameras have varying IR cut filters in front of the sensor.  I should run some experiments with IR cut filters to see what the IR sensitivity looks like.
