Apeture Settings

To further the development of my photographic skills, I was asked to take multiple images that were focused on an interesting item. I was asked to change a setting on my camera called the aperture. Changing the aperture on a camera adjusts the lens inside to make it larger or smaller. This either allows more or less light to be allowed into the lens and whether the whole of the image is in focus or not. Altering the aperture allows you to create photos that have an unfocused background and a focused background, therefore making the subject stand out or creating a photo that blends in with everything. I took three different photographs, all with a different aperture size, F4, F9 and F22. 

The first image that I took was with an aperture of F4. Using an aperture of F4 makes the lens inside the camera larger, therefore letting more light in and needing a quicker shutter speed. As you can see from the image above, the clock is in focus and the background is blurred. This feature can be used to make a subject stand out in the picture.

The next photo was taken with an aperture of F9. As you can see from the above image the clock is blended more with the background. Using an aperture of F9 makes the lens inside the camera smaller. By making the lens smaller, less light is allowed into the camera, therefore needing a longer shutter speed. Photographers will use an aperture of F9 if they are creating an image that blends together.

As you can see from the image above I have captured the image with an aperture of F22. Capturing an image with an aperture of F22 makes the camera lens smaller, therefore letting less light into the camera. When this occurs a longer shutter speed is needed in order to let the correct amount of light into the camera. Using an aperture of F22 makes the main feature blend in with the background, as the whole image is in focus. A photographer would use this aperture if he wanted to create a crisp image that has no set feature that the audience would need to be directed too.
