Aperture Settings

F-Stop
The opening behind the lens in a camera is called an aperture. The number of the f-stop denotes the width of the opening in the aperture. The larger the f-stop number the smaller the opening in the aperture which means the more light is allowed in. The light reacts with cells in the camera to form an image. Controlling this determines the depth of field which refers to the depth of focus. Large apertures offer limited depth of field, small aperture enables lots of depth of field. The larger the field of depth, the more the background is out of focus. The more the smaller the field of depth, the more the focus. 


The f-stop of this photo is F3.5 This means that the background is out of focus because of the small depth of field. This can be used for portraits.


The aperture of this photo is F9. This means the background is party out of focus as the aperture is in between small and large. This can be used



The aperture of this photo is F22. This means that the whole photo is in focus because the field of depth is large. This can be used to establish backgrounds and also for setting the scene.

I think that I used this skill effectively. I managed to take photos of different f-stops and compare them. A strength of the way I have used this skill is how the object I had taken a photo of was always in focus and was significant within each shot. A disadvantage is how the background is still slightly blurred even with the maximum field depth.

This skill can benefit me with my unit 3 production when I take the photos. It had taught me how to make the object I am taking a photo of significant. It also means I can make the reader focus on the object and block out the background.

I can keep experimenting with this skill to develop my progress further and succeed in making the background focus on maximum depth field.
