Negative space in design

In amateur art classes, artists are taught to keep three things in mind while designing: frame, positive and negative space. The frame is of course the border of the picture and positive space is the area occupied by the object drawn. Negative space is defined as the space that is around an object but inside the frame. Utilizing this space brings balance in the picture and harmony to its composition. The image created by the negative space may either be the subject of a picture or it may help that subject stand out.
