What is Aperture?
The aperture controls how much light enters the camera. It also controls the depth of field. Aperture is the adjustable lens opening that controls the amount of light allowed into the camera. Learning to properly adjust these three settings based on your location and subject is essential for capturing good exposures.
We tested using the aperture by taking pictures of things we collected from the beach, rocks, shells, flip flops, and other objects. Using two types of set up, first was an infinity table which gives the illusion of white space in the background of the image. We placed coloured jell sheets in front of the lights changing the colour of the images. Our second set up was using more natural light, with a white backdrop.
What is depth of Field?
Depth of field is the distance between the nearest and furthest objects giving a focused object that are in acceptably sharp focus in an image captured with a camera. The lower the depth of field, the closer you are to your subject.
Here is an example of different depth of field where on the right the background of the image is out of focus and the flower is in focus.
