Aperture

Aperture is how big or small the blades in the camera lens open. It is measured in f/stops, so for example if you used a low setting, say f/5.6, then the background of the image will be blury and the focal point will be clear and crisp. This is because the lens will have a wide opening, allowing in more light and a shallow depth of field. If you use a high aperture, say f/32, then the whole image will be very clear and crisp. This is because the lens will have a small opening. For these images I used an aperture of f/5.6 so that i could focus on one subject within the image to be clear and then the rest of it would be bury. This effect makes pictures look more interesting and more appealing to the eye.
