• The larger the aperture, the more light gets through the sensor. (Which affects the exposure of the image)
• f/number: divide the focal length by the effective diameter of the hole
• f/number sequence doubles every other step. 1.4, 2, 2.8, 4, 5.6, 8 – then it changes – 11, 16, 22, 32, 45 – but still pretty much doubles every other step.
• When using a small aperture like f/16 to sharpen the image. Use a large aperture like f/2.8 to sharpen the subject against a blurred background.
• f/5.6 is good for general uses because it produces an average depth of field.

• You have to set the camera into Aperture priority.
• f/1.4 through f/4 – The subject is the only thing in focus, the background is completely blurred, and objects are not noticeable.
• f/5 through f/7 The subject is in focus, the background is coming out more, and objects are beginning to appear.
• f/7 through f/16 – The subject is still in focus, but the background objects are a lot more noticeable. You can make out what is happening now. The background is not completely in focus because the camera limits were f/16.
• The larger the F stop the more depth of field there will be.
• The shutter speed starts to change as you increase the F stop.
