Aperture F2.8


Aperture F16

Questions:
1. We should relate the aperture to the pupil of an eye, in which they both grow bigger to allow light and shrink to prevent light from getting in.
2. The smaller the aperture, the more blurry the background will be and the lens will be bigger. The bigger the aperture, the background will be sharper and the lens will be smaller
3. When there is a shallow depth of field, there is a clear subject but the background will not be as defined. When there is a deep depth of field, then the background and main subject will be clear.
