Sometimes I, like many photographers, mention the camera’s settings when posting a photograph or when explaining how to set a camera for different types of photography. These settings look much like this: f/2.8, 1/125s, 400mm, ISO: 200. These are the lens’s and sensor’s specifications during the shot and are controlled by the camera automatically or by the photographer manually on the lens or in manual mode (M), program mode (P), aperture priority (A or Av), shutter priority (S or Tv), the camera’s zoom controls, and internal menus.
I think it would be interesting to see among the photography community who is currently considered the best living photographer.
I know I missed many, please feel free to add yours
