Photography is an art in which the level of creativity is immeasurable and inevitable. That’s why photography has a huge amount of styles, techniques and forms. A camera allows for several possibilities which can all be used creatively. For instance: A camera contains a zoom lens and a focus, if we utilize both of them perfectly then we can create depth of field.

Depth of field is actually the amount of distance between the nearest and the farthest objects which appears in the sharp focus. Depth of field surely adds to the beauty of a photograph and it also simultaneously shows photographer’s creative side. If you take a large depth of field into consideration such as f22, such as the Sony 50mm 1.4, then it will keep most of the frame in sharp focus whereas f4, which has mainly a small depth of field, focuses on the subject. For selecting a desired depth of field you have to take into account object distance and image size, the bigger lens you have, the narrower the band of depth of field. For more depth of field you have to place your camera farther from your object. Depth of field will decrease with an increase in the focal length because a long lens will give less depth than a short if subject distance remains the same. To get the right depth you must know what is hyper focal distance in depth of field.

When a lens focuses at infinity, the depth of field begins somewhere in front of the lens and from that point the scene looks sharp whereas the subject become out of focus which comes between lens and that point. In short, the distance from the lens to that point is known as hyper focal distance.
