Light with Different Shutter Speed and Aperture.

For this piece of work, I have done several examples of using different shutter speeds to take photos of moving cars, a sunflower that I spotted on the way home and the amount of light let in when at night taking photos.
 The following 3 photos are of the sunflower on the way home and how I tried to vary the aperture and shutter speed to change the amount of light shown on the sunflower (whilst taking the photo, I had a person to shine a torch at the flower).

I took this photo with the shutter speed at 1/30 of a second and the aperture was F3.3.

Thiis was the second photo, in this the shutter speed was 1/10 and the aperture was F3.3.

This photo I feel helps the bright yellow colours of the flower stand out against the dark background. In this, I had the shutter open for 1/2 of a second and the aperture was again F3.3.


Passing Traffic

I live near a bridge/walkover, so I went there at night and took some photos of the passing traffic using different shutter speeds and aperture. This would change the amount of light let in. I had the setting on Shutter Priority, so that it would alter the aperture to fit with the shutter speed.

        The slow shutter speed gave the photo different effects, such as the length of the headlights of the car. Here is a picture of a slow shutter speed at 5 seconds and the aperture at F3.3... In this the lines of light stretch across almost the whole of the road.

                                              

Where as this photo taken with the shutter speed at 1 second and the aperture at F3.3, the lines of light did not go as far because less light was let in.

Different Angles

I tried to take a photo at a different angle to see if it made any major effects to the picture. When I took this photo, there were no cars going away from the camera at the time so there was not any red lights, it was not because of the angle. However, I did not think there was much difference in the photo apart from the light travelling at a different angle...

I also took a photo from the same angle, however I had the shutter speed considerably slower and I thought this changed the picture by letting even more light in than I could see. It made the sky look a lot lighter than I could see...

In this photo I had the shutter speed at 25seconds and the aperture was F3.3.

Aperture


As well as letting more or less light into the camera the size of the aperture you also change the 'Depth of Field'. Depth of field means the amount of the picture, from foreground to background, that is in sharp focus. A smaller aperture will give you a greater depth of field and a larger aperture will give you a more restricted depth of field.


If you look at the exposure display in your viewfinder you will see two numbers. On a normal sunny day you might see something like '125 16' or '500 5.6'. The first number is the 'shutter speed' and is simply the time that the shutter will be open for, expressed as a fraction of a second. So 125 means that the shutter will be open for 1/125th of a second, and 500 means that it will be open for 1/500th of a second.
The second number, sometimes referred to as the f-stop, tells you the size of the hole (aperture) in the lens. This number is also a fraction. The number represents the focal length of the lens divided by the diameter of the aperture. So an aperture that is 10mm in diameter in an 80mm lens will have an f-number of f/8 and the setting f/16 on the same lens will be 5mm across.


Shutter Speed
In photography, shutter speed is a common term used to show the length of time a camera's shutter is open. Here is an example of shutter speed. The flower to the left is at a fast shutter speed, the middle flower slightly slower and and the flower to the right is the slowest, I think that the flower to the left could be taken at a shutter speed of 1 second.
