I have a feeling that I did something strange.
I was testing Sofortbild, a software that allows tethered shooting. It works great. It allows control of the camera from the computer. I know there is other software that will do this, but this one is free. I don’t shoot like this very much but it is nice to have the option. Sorry, it only works with Mac OS.
