Experimenting with shutter speed and ISO to capture evening light trails on the A316. Starting with a quick shutter speed to capture moving cars in freeze frame; and progressing to a lower/slower shutter speed to get more interesting images – transforming moving vehicles into light trails.
Experimenting with shutter speed at Barnes station to emphasize motion blur on moving trains. Shutter speed was relatively slow and ISO was fairly high as it was an overcast day and sunset was fast approaching.
The affect that shutter speed has on a picture, to either freeze or show movement, works well with sports photography. The following images use fast enough shutter speed that the athlete (me) is frozen in motion, but you get a sense of movement/speed. The aperture in these photos also uses a slightly narrow area of focus for a subtle blur background.
