Aperture

What does aperture affect?

• Depth of Field is effected by aperture.
• How wide the aperture is to let the light in

Wider = less items in focus {smaller the number}

Narrower = more items in  focus {larger the number}  

Key factors that affect Aperture:

• F Stop {F2.8 or F22}
• Focal Length - Lenses {The longer the lens, the shallower the depth of field is, 400mm lends will give you a shallower D.o.F at F2.8 than a 50mm lens at F2.8}

Focal Length:

• The longer the lens, the shallower the depth of field is.
• A wide angle lens, would render an image with more depth of field than one with a telephoto lens.

Aperture Evidence {Greater D.o.F}:

EVALUATION:

• Here is my evidence for a Shallow D.o.F; this technique is achieved using a setting of f/16 or smaller, this will help to achieve a very deep depth-of-field. I personally don't think my evidence shows this technique prominently as there is a slight blur on the subject which shouldn't be there as everything in the shot should be crisp.

Aperture Evidence {Shallow D.o.F}:
EVALUATION:

• Here is my evidence for a Shallow D.o.F; this technique is used primarily to isolate the subject from its environment, you will mostly see this technique used in portraiture and macro photography. I personally don't think my evidence shows this technique prominently as there isn't a clear blur in the background, isolating the subject from its environment, you can only see it slightly through the blur on the subjects shoulders.
