PHOTOGRAPHY APERTURE
[OBJECT OF IMPORTANCE]
Bring in an object of importance. No phones, backpacks, etc... but instead to think about the object and how it can tell a story.
Working with a partner take turns directing them in different poses and compositions. You will edit a minimum of 20 photos (showing your angles/perspective/backdrop/lighting explorations) with your top 5 being a final edit.
Each photo has to have the object in focus with the person being out of focal range.
Play around with aperture (f1.8 - f3.5).

We will begin this project understanding depth of field. How do we control what is in focus and what is out of focus?
WHAT IS APERTURE?
Aperture is a hole within a lens, through which light travels into the camera body. It is an easy concept to understand if you just think about how your eyes work. As you move between bright and dark environments, the iris in your eyes either expands or shrinks, controlling the size of your pupil. In photography, the “pupil” of your lens is called your aperture. You can shrink or enlarge the size of the aperture to allow more or less light to reach your camera sensor. The image below shows an aperture in a lens:

EFFECTS OF APERTURE: EXPOSURE
Aperture has several effects on your photographs. One of the most important is the brightness, or exposure, of your images. As aperture changes in size, it alters the overall amount of light that reaches your camera sensor – and therefore the brightness of your image. A large aperture (a wide opening) will pass a lot of light, resulting in a brighter photograph. A small aperture does just the opposite, making a photo darker. Take a look at the illustration below to see how aperture affects exposure EFFECTS OF APERTURE: DEPTH OF FIELD The other critical effect of aperture is something known as depth of field. Depth of field is the amount of your photograph that appears sharp from front to back. Some images have a “thin” or “shallow” depth of field, where the background is completely out of focus. Other images have a “large” or “deep” depth of field, where both the foreground and background are sharp. WHAT IS AN F-STOP or F-NUMBER? So far, we have only discussed aperture in general terms like large and small. However, every aperture can also be expressed as a number known as an “f-number” or an “f-stop.” Whenever you see an aperture value, the letter “f” will appear before the number, like f/8. Most likely, you have noticed this on your camera before. On your LCD screen or viewfinder, your aperture will look something like this: f/2, f/3.5, f/8, and so on. Some cameras omit the slash and write f-stops like this: f2, f3.5, f8, and so on. For example, the camera on the side is set to an aperture of f/8. |
