The screen is flat — foreground gives it 'thickness'
The screen is 2D, but a good image has depth. The easiest trick is to add a foreground: put something between the lens and the subject (a blurred flower, a railing, a silhouette), and the image instantly splits into front / middle / back layers, gaining a sense of dimension.
Frame within a frame: use a door, window, mirror, or branches to 'frame' the subject. It focuses the eye and naturally carries a feeling of 'peeking' or 'being trapped.'
Foreground isn't just pretty — it expresses
Shooting through railings / a gap = voyeurism, surveillance; shooting the lead through a blurred crowd = isolation; a doorway boxing someone in = trapped, watched. Foreground is emotion and layering you can add for free, and beginners overlook it the most.
