This was photographed with the D850 resting on the floor and in live view, with the back LCD angled up for easy viewing. In this mode, touching the screen will initiate autofocus and then the shutter will automatically release… silently.
It’s a well-known feature in the D850 but this is the first time I’ve tried it.
Many find Nikon‘s implementation of all this to be slow (relative to mirrorless cameras), but it’s quite usable for this sort of image. It’s certainly useful in quiet venues where silent operation is desired.
However, I wouldn’t think of using it to photograph sports, flying monkeys, or the aerosolized droplets of a sneeze.
