While saving up my spare cash to buy a Canon 50D for my birthday, I’m taking the time to brush up on some of the basic (and not so basic) skills one should learn when getting serious about photography.
One of the topics that can stump a newbie is hyperfocal distance. With the switch to digital photography, many people have forgotten or have not even learned what hyperfocal distance is. To understand what hyperfocal distance is, you first need to understand depth of field.
When you focus your camera lens on an item, there is a zone or field in with everything is in focus. When you stop down (make the aperture smaller / ƒ number bigger) the depth of this field becomes larger. This depth of field can be quite small with macro or telephoto lenses; shorter lenses, like a wide angle lens, can have more depth of field.
Now that we have an understanding of depth of field, why is hyperfocal distance important? If you like to shoot landscapes like me, this concept really comes in handy. If you want to keep my foreground subject focused and also have the background in focus, you need to adjust my depth of field so that it extends from the foreground subject to infinity… and that in a nutshell is hyperfocal distance.
So, how do you determine distances, aperture settings, etc. to properly set the hyperfocal distance on your camera? I’ll discuss how and provide some useful resources in Learning About Hyperfocal Distance, Part 2.
