How to Write Interior Design Prompts - Nano Banana 2
Interiors are shot from a corner, camera at roughly chest height, so that two walls are visible and the room has depth. Centred head-on views flatten a space into a stage set. Say which corner and what is in the foreground: “shot from the corner near the doorway, the arm of an armchair entering the bottom-left of the frame” gives you a photograph. “A modern living room” gives you a rendering.
Focal length matters more here than in almost any other subject. Sixteen or eighteen millimetres takes in a whole small room but bends the walls and stretches whatever sits near the edges. Twenty-four is the working standard for property and magazine interiors — wide enough to show the space, honest enough that the furniture keeps its proportions. Thirty-five gives a tighter, more editorial slice of a corner or a detail. Ask for straight verticals unless you specifically want a leaning, handheld feel.
Furniture named by category gives you generic furniture. Named by material and finish it becomes specific: bouclé upholstery, oiled walnut, powder-coated black steel legs, unlacquered brass handles going dark at the edges, wide oak boards, microcement, terrazzo, a wool rug with visible pile. Name the walls and floor too — plaster with a slight texture is a different room from painted drywall.
