In most cameras, including my Nikon Z7, in the knob we have to set Manual, Aperture, Speed, Program, and Auto, I am not sure to understand what is the difference between the P (Program) mode and Auto Mode. In the User Manual says that Auto Mode, is A “point-and-shoot” mode in which the camera sets exposure and hue. In the Program Mode, the camera sets shutter speed and aperture for optimal exposure. Recommended for snapshots and in other situations in which there is little time to adjust camera settings. But I though the Auto Mode would do the same. Can someone explain precisely what is the difference between the two ?
