When the shutter is open, a picture is being taken, when it closes, …
Most of the time, a good digital camera is pretty adept at sensing the lighting conditions and selecting the optimal shooting settings. Auto and the no-flash auto lets the camera do the thinking and the photographer do the snapping, often resulting in clear, well lit photos.There’s just one problem—cameras can’t actually think.
