Many photography books define Depth of Field (DOF) as “the distance between the nearest and farthest objects in a scene that appears acceptably sharp in an image”. Obviously for a lay man or a beginner in photography this definition does not explain anything. More often than not it creates more confusion than explanation. To make it easy we can say that “Depth of Field” is a common technique used in portrait photography in order to perfectly focus an image, while its background and other images in the photo seem to be blurred (See picture below).
This effect can be pretty dramatic as long as it is done properly. Without mastering the art of depth of field, your photo might just end up messed up, and sure enough, you don’t want this to happen to your image. Do you?
Regardless of the brand and camera model that you’re using, you can master the technique depth of field. This is the range beginning from front towards the back of the image that is currently in focus. You can focus the background and the foreground; while on the other hand, you can create an image wherein one object is focused while the background is slightly blurred. Your choice of focus will help you determine the image quality of your picture.
There are different DSLR cameras that allow you to easily control the DOF or Depth of Field. Most often, there is a tiny button that allows you to set the DOF and trying to play with these effects will help you hone your skills. Try experimenting some of these settings and adjustments and in no time, you will be able to create that dramatic effect that everybody will want to know. It’s not just about the quality of your SLR, but it is also about your skills and your understanding about Depth of Field.
The good thing about technology is that there are different types of cameras that are now released to make it easier for you to focus on an object and set a DOF of your preference. Additionally, there are a lot of resources and even video tutorials that you can look for in order to hone this skill and master the depth of field technique.
