The Negative Space rule encourages you to minimize the size of your subject in relation to the background. Negative space is the area around the subject in the scene, and when applying this rule, it should take up more of the scene than your subject. Although it may not be intuitive, this has the effect of drawing the viewer’s attention to your subject. Using negative space, you can create quiet photos with feelings of solitude, relaxation, and contemplation.
The guiding lines indicate the negative space, areas to simplify by removing elements and blending colors and lighting. The negative space doesn’t need to be a completely blank area. Things can be happening, but they should blend in the background and not distract from the subject.
To apply this rule, slow yourself down and look at the area surrounding your subject. Move around your subject to find a point of view that isolates the subject from the background. Tap the screen to move the guiding lines.
