Playing with light and speed

I’ve got more photos for you. I was playing with shutter speeds in this series. I wanted to see what would happen in various situations. None of these photos are stunning but a nice learning process. All images have been cropped but not otherwise altered.

Some long shutter (bulb setting) for fireworks.
18mm
1/1.3s
f 3.5

Really long bulb.
18mm
43.7s
f 3.5

Trying for the light/dark silhouette.
55mm
1/40s
f 8

Playing with trying to capture motion blur. Used shutter priority setting.
29mm
1/30s
f 7.1

And again. Shutter too slow for what I wanted. The motion almost disappears.
29mm
1/10s
f 8
