"Dragging the Shutter" revisited
1/100 @ f1.6 @ 1000 ISO "Dragging the Shutter" is a term used to describe the technique of using a slow enough shutter speed to allow a measure of ambient light to register when using flash. This term originates from an era when photographers would determine correct flash exposure for on-location photography by : - setting the ISO speed according to the film used, - setting the aperture according to subject distance (depends on flashgun's guide number), - then using the shutter speed as the ONLY way of independently allowing more ambient light in, slowing the shutter speed far lower Read more inside...
