What Is Depth of Field (DOF)?

Depth of field (DOF) is simply the part of the image that appears to be sharp. Usually, the images in front or at the back of the depth of field will appear to be blur. So, if you want to increase the sharpness of your picture, you need to increase your depth of field.

However, there is no standard usage for depth of field. What you think should be the depth of field might not work for other photographer. This is because different photographer has their own taste of enhancing their photos.

There are a few factors that determine the depth of field. But usually, depth of field can be determined by:

1. The aperture (the f-number) – the smaller the aperture (the larger the f-number), the more depth of field.

2. Focal length – wide angle lens will have stronger depth of field than telephoto lens.

3. Distance – the further the camera from the subject, the more depth of field you will get.
