Day 3 – Aperture
• Take a photo with a Shallow Depth of Field. (Lowest f/stop number)
• Take another photo with a Deep Depth of Field. (Around f/16-22)
You will want to use Aperture Priority on your camera to control this particular setting.
• The aperture helps control the amount of light that reaches the sensor in the camera.
• The aperture also controls the depth of field in your image.
- Low Number (Wide Aperture): Less of the photo in focus
- High Number (Narrow Aperture): More of the photo in focus
- Lenses will vary in how low/high the aperture can go.
• Using an extremely high f/stop number (higher than f/22) is not as affective as you would think. It will confuse the optics in the camera and your photo will be soft.
• Around f/22 for a deep depth of field is a common f/stop.
• When shooting with a shallow depth of field, be sure to focus in the areas that you want in focus; otherwise a random area will be in focus. This can be a problem when shooting a portrait. For example: if you focus on the person’s nose but you have a very shallow depth of field, then their eyes may be out of focus. You would want to focus on their eyes instead so that the eyes are in sharp focus.
