Depth of Field Explained
What is depth of field?
Depth of field is one of the most important aspects of photography. This feature of the camera enhances creativity and creates a focus point for the eye to latch onto. Depending on the photo, having a main subject with the clearest focus will create a more pleasing overall aesthetic.
How can you control depth of field?
Changing aperture settings on the camera is the key to controlling the depth of field. Aperture is measured on a scale of "f-stops" which are measured in numbers like 1.4, 2, 4, 8 and so on. The key component to knowing how to control aperture is that the larger the aperture is, the shallower the depth of field is. A smaller number denotes a larger aperture.
