I decided to go into Manchester city center to take some photographs demonstrating the effects of different shutter speeds and apertures on different subjects and scenes. Below is a contact sheet of the images I took. I used a nikon D90 with a 50mm prime and an 18-55mm lens. I chose the 50mm because it has a very large aperture of f/1.8, good for isolating and focusing on subjects and the 18-55mm for very wide dynamic shots.
Here are the final shots I liked the most.

| 1/500 f/1.8 ISO200 |
 |
| 1/400 f/1.8 ISO200 |

The large aperture helps keep the attention on the subjects and not anyone in the background.

| 1/15 f/9 ISO400 |
Here i used a higher aperture but kept the images focal point as the woman by using a slower shutter speed to blur the moving pedestrians.
