How does using a window or door to frame your subject make the picture feel deeper and tell you more about where the subject is?

Using a window or door to frame a subject significantly enhances the picture's perceived depth and provides rich contextual information about the subject's location. This technique, known as sub-framing, establishes a clear sense of three-dimensionality by creating distinct visual layers. The window or door itself acts as a foreground element, the subject is positioned in the middle ground, and the scene beyond the subject forms the background. This layering creates a strong illusion of recession into space. One crucial depth cue this method utilizes is overlap, or occlusion, where the frame partially blocks parts of the subject or background, unequivocally indicating that the frame is closer to the viewer than what it contains. Furthermore, the converging lines of a window or door frame, especially if it recedes, provide powerful linear perspective cues, guiding the viewer's eye deeper into the scene and emphasizing distance. The relative size of the frame's elements, appearing larger due to their proximity, also serves as a visual reference point for the comparative size and distance of the subject and background, reinforcing depth perception. Beyond creating depth, the window or door frame immediately communicates extensive contextual information. Its architectural style, materials, and condition reveal the nature of the subject's environment, such as whether it is ancient, modern, urban, or rustic. The view visible through the frame directly identifies the specific location, for instance, a bustling city street, a serene natural landscape, or a particular interior setting. This not only specifies the location but also implies the relationship between the subject and their surroundings, suggesting, for example, a moment of observation, enclosure, transition, or a boundary. The quality of light filtering through a window or doorway also provides authentic atmospheric and temporal cues, further grounding the subject in their specific time and place. This comprehensive visual information gives the viewer a deep understanding of where the subject is situated.
