You don’t have to be a pro to take beautiful landscape pictures, but knowing your way around your camera settings can make a dramatic difference. The three pillars of landscape photography are ISO, aperture and shutter speed. Together, these make up the ‘exposure triangle.’
ISO is a number that’s linked to your camera’s sensitivity to light. The higher it is, the more sensitive your camera is. For clean landscape shots, the general rule of thumb is to stick with the base ISO, which is usually between 100 and 200. If you’re shooting a darker scene or a moving object, you’ll want to raise the ISO to prevent blurriness. Just keep in mind that higher ISO settings can leave you with ‘grainy’ or noisy pictures. (This is one reason why photographers are always chasing good lighting – more on that in a minute!)
Aperture describes the size of the lens opening, which lets in light. When you hear photographers talking about f/stops, they mean the aperture. To take detailed landscape photos, create a large depth of field using a smaller aperture, such as f/13, f/16 or f/22. This will keep the background and foreground of your image in focus. Aperture confuses many new photographers because a smaller aperture is a higher number.
