The important thing to know about apertures is this: while a wider aperture lets in more light, it is not always better. When your aperture is wider, the light coming in from different objects in the frame converge at different distances, which leads to only some of the light converging precisely where the sensor is located. This is why a wide aperture has a shallow depth of field as only some part of the field of view can be in focus at a time. When the aperture is narrower, the light has a smaller opening to spread through and more of the light coming in tends to converge at the same point, which is why you see more things in focus and get a bigger depth of field (or depth of focus). It's also why a smaller aperture results in sharper images (and why we tend to squint if our eyesight is weak). Photographers know this, which is why most of them will stop down the camera to f5.6 or slower when shooting outdoors in sunlight to get as much sharpness and detail as possible, unless the photographer very specifically craves a shallow depth of field shot.
