The depth of field is when you focus the viewer’s attention is a specific area. It’s controlled by changing the aperture setting on your camera. You can control how you want it. How you want the eye to catch the main view. The larger the aperture, the shallower your depth of field will be, meaning a smaller portion of your image will be focused. Depth of field control is one of the most important tools in your creative arsenal.
You want to let much light in as possible. You can struggle to get fast enough shutter speed to get a sharp image. As you make your aperture smaller, you need to have a longer shutter speed to let the same amount of light through to the sensor. This type of photography can be very important because it can sharpen the focus which is an important role in photography.
