This picture shows an example of both a long EXPOSURE to light and a slow SHUTTER SPEED. The long exposure to light allowed more light to pass through the camera and capture the lights of the cars passing by as the shutter reamined open. As you can see, everything in the picture is still in focus and sharp, meaning there was absolutely no CAMERA MOVEMENT invlolved. in addition, the photographer may have changed the FILM SPEED, using a higher ISO SETTING to make the camera more sensitive to the light. http://photography.nationalgeographic.com/staticfiles/NGS/Shared/StaticFiles/Photography/Images/POD/s/street-light-exposure-florida-93001-xl.jpg
These pictures were taken my a professional photographer named Diana who worked at the resort we were staying at while my mom and I were on vacation in Cancun last spring break. the picture at the top shows that she used a small APERTURE (large F-STOP) in order to get a larger DEPTH OF FIELD, keeping everything in the picture in focus. But, in the picture at the bottom, she used a wide aperture, decreasing the depth of field, only keeping me in focus.
