Depth of Field

 DEPTH OF FIELD:

Definition: it is the distance between the nearest and furthest elements in a scene that appear to be "acceptably sharp" in an image. In simpler words, depth of field is known as the area in sharp focus. 

Depth of field can be categorized into two: 

Deep Depth of Field: a larger area in focus, and more of the image is sharp and clear. It is usually used in landscapes, or group photos. 

Shallow Depth of Field: it puts focus on a certain area, or the subject, and the foreground or background is mostly blurred, Portraits might use shallow depth of field.

This picture of a cat, for example, uses a shallow depth of field, where the subject, i.e. the cat is in sharp focus, whereas the rest of the picture is not in sharp focus, called bokeh.

Bokeh is known as the aesthetic quality of a lens to do blurs. So the blur part of a picture is called bokeh.

A landscape picture can be categorized into three grounds: 

Foreground 

Middle ground

Background

Positive and negative spaces in a picture:

Positive Space in a picture is the part that stands out from its surroundings. It can include the subjects, or other noticeable parts or features.

Negative spaces in the picture are ones that don't draw as much attention, and are more secondary in the picture compared to whatever is included in the positive spaces.

Attempts of bokeh by me: "Sushi".
