What is Aperture?
- The aperture is a hole inside the camera lens that controls the amount of light entering the camera, similar to the pupil in your eye.
- In photography, the aperture is represented by the letter ‘F’ followed by a number (e.g., F4, F22).
- A larger aperture (lower F-number) lets in more light, while a smaller aperture (higher F-number) lets in less light.
By experimenting with different apertures, you can learn to create various photographic effects, enhancing your skills in capturing stunning images.
Do the Aperture Experiment
Watch the video then do the experiment. The experiment steps are below –
Step 1 – Set up the Camera
Mount your camera on a tripod.
Set your camera to aperture (AV mode).
Set ISO to 100.
Position your camera at an angle to a wall or fence with a repeating pattern, focusing on a specific point.
Keep your camera in the same position on the tripod for every shot.
Step 2 – Take the Photos
a) Take a series of photos, changing the aperture for each shot:
Start at F4 (wide aperture), and take a shot.
Then, move to F6 take a shot, F8 – shoot, F11 – shoot, F16 – shoot, and F22 (small aperture) – shoot.
b) Look at how the depth of field changes with each photo.
At F4, the depth of field is shallow, with only a small part of the image in focus and the rest blurred.
At F22, the entire image has a large depth of field, with all of the image in focus and sharper.
Step 3 – Blog Your Results
Write a blog post on your website and add at least three photos.
Examples of what to write are on your website blog post ‘Aperture Settings’.
Plus read this step by step guide which lists exactly how to publish it on your website.
