I'm trying to film myself sitting on a sofa talking.
The problem is, with auto-focus, occasionally the camera can lose focus, for example if I lean forward or back or gesture.
What I want to do is auto focus at the start then simply keep the focus fixed.
I can put my camera into manual focus, but since I'm not in the picture on the sofa, I can't really focus it.
Do I have to put a dummy object where I would sit in order to manually focus? Or is there a better technique than this?
I'm asking as a camera-agnostic question, but I have a panasonic lumix g90 which has a physical dial for choose auto-focus modes or manual. I tried using the app to remotely control it, but I guess as it's a dial, I can't change it? Also since I can't see the screen while I'm sat down, focusing it using an app would be quite tricky anyway.
I figure this is a common enough situation to have a solution to it, if anyone has any ideas.
