One of the problems in photography is that the human eye automatically compensates for specific light conditions. It is for this reason, that we use exposure meters.   Most of the cameras also have built in exposure meters to assist the photographer. These exposure meters however sample the complete picture in the viewfinder or only a selected area in the viewfinder depending on the design of the camera. For...

But only one, sometimes two, of these combinations of f/stops and shutter speeds is the creatively correct motion-filled exposure. Again, let’s review, that every ‘correct’ exposure is nothing more then the quantitative value of an aperture and shutter speed working together within the ‘confines’ of a predetermined ‘ISO’. For the sake of argument we are both out photographing a city skyline at dusk, using a film speed of 100 ISO and an aperture...
