In Today’s Photo Minute video, Brian Osborne discusses how some mid to high level cameras allow the user to lock the aperture or shutter speed or both. This can prevent the inadvertent change of the chosen aperture in Aperture Priority or Manual mode or the shutter speed in Shutter Priority or Manual mode. In addition, as demonstrated in the video, on many Nikon camera models, this ability to lock the aperture or shutter speed function does not have to be done underneath the menu each time but can be done with custom control setup.
