The camera has a switch, which lets you turn off Live Photos. That used to be sticky, but it no longer is. When you open the camera, it is always enabled. Since I mostly shoot still objects, there is a lot of wasted space in storage.
As it turns out you can make this toggle stick by going to Settings/Camera. There are more interesting switches that disable automatic behaviour.
Danke für den Tipp. (Auch wenn ich eher in die Kategorie: “Oh, wieso ist Live-Foto deaktiviert!” gehöre und die Änderung von Apple quasi begrüße….)
