Using Av mode (Aperture Priority) on your Canon camera lets you control the depth of field in your photos, while the camera automatically selects the appropriate shutter speed for proper exposure. Here's how to use it:
Steps for Using Av Mode
-
Set the Mode Dial to Av: Locate the mode dial on your Canon camera (usually on the top right). Rotate the dial until it points to "Av". This puts your camera in Aperture Priority mode.
-
Choose Your Desired Aperture: The aperture controls the amount of light entering the camera and the depth of field (the area of your image that's in focus). Use the main dial (usually located near the shutter button or on the back of the camera) to adjust the aperture value.
- Lower Aperture (e.g., f/1.8, f/2.8): Creates a shallow depth of field, blurring the background and isolating your subject. Ideal for portraits and isolating details.
- Higher Aperture (e.g., f/8, f/11, f/16): Creates a large depth of field, keeping more of the image in focus. Ideal for landscapes and group photos.
-
Focus on Your Subject: Press the shutter button halfway down to activate the autofocus system. Make sure your subject is in focus through the viewfinder or on the LCD screen (if using Live View).
-
Check the Display and Shoot: Look at the display (viewfinder or LCD). The camera will automatically choose a shutter speed to match your selected aperture for correct exposure.
-
Shutter Speed Display: If the shutter speed is blinking or shows as a very low number (e.g., 1/15 or slower), it indicates that the camera might need more light to get a proper exposure.
-
Adjust ISO if Needed: If the shutter speed is too slow (causing potential blur), you can increase the ISO setting to make the camera more sensitive to light. Be aware that higher ISO values can introduce more noise into your images.
-
Use a Tripod: If you need to use a slow shutter speed, consider using a tripod to stabilize the camera and prevent blur.
-
Shoot: Once you are happy with the settings, press the shutter button fully to take the photo.

Tips for Av Mode
- Experiment with Different Aperture Settings: The best way to learn is to experiment! Take the same photo with different aperture values and see how it affects the depth of field.
- Consider Your Subject: Think about what you want to be in focus. If you're shooting a portrait, a shallow depth of field can be very effective. If you're shooting a landscape, you'll likely want a wider depth of field.
- Understand the Relationship Between Aperture, Shutter Speed, and ISO: These three settings work together to create a properly exposed image. Learning how they interact will give you more control over your photography.
