Aperture, what is it?

The aperture may be used to adjust the depth of field of an image. The largest aperture setting on the Nikon D40X camera is F4.8, and the smallest aperture setting is F22. The larger the aperture the lower the depth of field. Conversely, a smaller aperture will increase the depth of field.
