RULE OF SPACE... this rule states that if the subject is not looking directly to the camera, or looks out of the frame, there should be enough space for the subject to look into. The image should present the subject (when it is looking away from the camera or moving in a particular direction) with more active space and less dead space. The active space is the area where the object is facing or moving. This composition technique is important because when someone views an image and spots that your subject is moving in a particular direction, their eye naturally moves in that direction too. This aspect builds anticipation and creates a strong impact, it shows that the subject has a destination. In simple words Rule of Space creates a sense of direction and motion.
Following this guideline can help in achieving an impactful image, it can also add value if the rules are broken once in a while, to break the monotony and to introduce a fresh perspective or a creative approach to the photograph. It is suggested that the amateurs and beginners follow this technique to make their images better, these rules can be broken depending on what the subject is, after the photographer masters the basic composition guidelines.
