Exercise: shutter speeds

Place: Light train (Metro) in Bergen
Equipment: Nikon D300 with 17-55mm f/2,8
Camera on tripod

To change the shutter speed I adjusted the aperture for each frame. I used the camera in Aperture mode.
That means I set the aperture, and the camera adjust the shutter speed needed to get a correct exposure.
I started with f/2,8. That gave a shutter speed of 1/125 sec. My ISO setting where set to 640
The light train is pretty sharply frozen at this shutter speed.
Shutter speeds in between the fastest and slowest frames where not very pleasing to look at.
The slowest shutter speed I used was 1.3 sec. That gave the train horizontal lines due to the lights and he colorful design. I personal like images with a lot of movement. I could have used an even slower shutter speed, but the train would become a bit too transparent, I think

Some of the images from the exercise: (I did not pay very much attention to the composition)
