Thanks for the explatations, seems if EXIF tags are rather related to images and not the camera itself. But I am seeking for a way, that while I am running my Python program, I can get info fram my RPi camera such as aperture, exposure time, ISO etc. which the camera sets automatically. I want to especially know the exposure time because from that I can define how light or dark the environment is. This is helpful for determining the daytime of an image.
The information you want is mostly available via the picamera class: https://picamera.readthedocs.io/en/rele ... e-picamera
However, exposure time alone isn't enough to tell how dark or light the environment is. Exposure time will be affected by ISO and othe gain settings. Change one you change the other. See here for an explanation but ignore aperture changes as it's fixed on the camera modules: https://photographylife.com/what-is-exposure-triangle
