One of the basic rules of landscape photography is to use slow apertures to create a deep depth of field and ensure sharpness. If you use a fast aperture like f/4 or f/2.8, it can result in a blurry foreground or background depending on your focus distance and your camera’s sensor size. If you use a wide angle lens, the blurring effect may be less noticeable at first but is more perceivable if you view the image on a large screen or in print.
