Depth of Field example

 

The two images in the picture above were taken using different apertures to show depth of field. I used a Nikon DSLR on a tripod with a fast shutter speed to make sure the image was not blurry. I also placed to subjects in the image, one close to the camera, on futher away to show how the aperture affects how much is in focus. The lower the aperture, the less in focus which means it has a shallow depth of field, as seen in the first image. When the aperture is open less (but the f-stop number is higher), more of the image will be in focus.
