Wondering how to create that blurred background effect in your images? Just set your camera to Aperture Priority (AV), choose a large aperture setting (represented by a small number (like f/2.8, f/3.5, f/4, f/5.6), stand back from your subject and zoom in to fill the frame. That’s all you have to think about, the camera makes the decision about the shutter speed for you, depending on the light in your scene.
