When parallel rays of light strike a lens focused at infinity, they converge to a point called the focal point. The focal length of the lens is then defined as the distance from the middle of the lens to its focal point.

The Crop Factor is a term that can be heard quite often in the world of digital photography. What does it mean that a camera has a crop factor of 1.6x and how does it affect your focal length? We try to untangle this issue and describe it as clearly as possible.

The subject of crop factors and focal length multiplier can be a bit confusing and hard to understand at first — we will try to explain it as simple as possible but yet informative enough for you to get the entire picture.

Have you ever got home after what you thought was a great day’s photography, only to upload your images and find that they were sharp in either the foreground or background but with the rest of the image not quite in focus?

By applying the simple rules of Hyperfocal Distance you can be sure that you are shooting images which are sharp from foreground to background on almost every occasion. We will be using an image that we took recently of Castlerigg Stone Circle to show you how you can put these simple rules into practice so that you can obtain maximum depth of field (DOF) in all your landscape images.
