Depth of Field

For this section I will be showing how zoom and aperture effects the depth of field of a photo.

First of all I will show 2 photos showing the same flower head, but one without zoom and the other using the zoom but moving the camera away from the flower head and keeping it in focus.

I will now show the difference that aperture has on the photo. By lowering the aperture it gives the image a bigger depth of field as it becomes more blurred.

f.2.8 f.8.0

Using a higher aperture gives more detail and focus to the background. We can see that f.8.0 gives more details to the conifers and grass and alternatively we can see that f.2.8 makes everything except what the camera is focused on blurred.

As we increase the aperture controls the amount of light that reaches the image sensor or film. The higher the aperture number the smaller the hole that allows light to enter the camera, which means the longer the shutter speed will have to be for sufficient light exposure.
