1. Aperture is the size of the opening of a lens.
2. Aperture change is similar to the way that the pupil dilate to control how much light enters the human eye.
3. The aperture determines how much light will enter through the lens and control the depth of field (DOP).
4. Aperture is measured in f-stop numbers.
f 64, 32, 22, 16, 11, f 8, 5.6, 4, f 2.8, 2, 1.4, 1.2, 1.1, 1

a) The smaller the f-number, the wider the aperture and reduces the depth of field.
b) The bigger the f-number, the narrower the aperture and extends the depth of field.
Why use a small aperture?
1. Increase depth of field in close-up shots to ensure the whole scene is in focus, from front to back. (Important when shooting landscape scenes)
2. Capture the optimum degree of fine detail - so narrow apertures are great for deep landscape and building shots.
3. Narrower apertures allow slower shutter speeds for creative motion-blur effects, and striking light trails at night.
Why use a small aperture?
1. Reduce depth of field to focus attention on your subject while keeping the background nicely blurred.
2. Isolate an object from a distracting background.
3. The more light that's allowed onto the sensor, the faster the shutter speed you can use to freeze action, or stop camera shake from spoiling your shots.
4. Create arty abstract shots with a macro lens by carefully controlling what is sharp.
