Another challenge for beginning photographers is learning how the camera sees differently than people do. We are used to looking at a scene with near and far objects and seeing all of them as in focus. But a camera can only focus at one distance at a time. To get near and far clear, we have to change the camera's aperture.
Using a small aperture (represented by a "big" f-stop number) along with a wide-angle lens can help you get everything from close to the lens to the horizon in acceptable focus. In the image here, I set the aperture to f/22 (the smallest opening) and used a 24mm lens. This created an image where both the near old gas pump and the distant hills are all sharp.
