There are two benefits of using a slow shutter speed: a lower ISO and artistic motion blur. I’ve shot with a slow shutter courtesy of image stabilization for both purposes. When used with Auto ISO, a slow shutter ramps down the ISO value, resulting in a higher-quality image.

I certainly benefitted from an optimized ISO at a 1/2-second shutter speed, but my primary attempt was to blur the church visitors for a creative effect. There’s a risk with too slow a shutter since the church details can also suffer. I managed to hit the camera and lens’ limit handheld.

Motion blur can be a blessing or a curse. It’s not good if you want sharp details. However, if done correctly, it adds visual interest and a sense of movement. The solid stone architecture makes for a worthwhile contrast to the fleeting motion of the people.
