We bought a camera a few years ago.
xxx: and after a while his wife started complaining that sometimes the camera disappears the image on the screen
xxx: after careful inspection, it was not possible to reproduce glucose
xxx: and yet she complained that the screen regularly shows nothing
After a couple of months, I was able to find out that glucose is only in the bright sun.
XX: I still have no glucose reproduction
xxx: so, she usually shot on the camera in polarization sunglasses and when she turned the camera 90 degrees - the picture naturally disappeared.
