Rule of Odds in Photography Framing Focal Length Infographic

Educational infographic poster titled "Framing Within a Frame: Focal Length Comparison" in landscape layout, with sharp readable text labels and clean hierarchy. Show a minimal flat technical educational design comparing how framing within frame changes across focal lengths, using accurate photography guidance and no real camera-brand logos. Include 5 numbered panels arranged left-to-right with sequence numbers, thin arrows connecting each panel, and a small legend for focal length effect. Each numbered component must include an English bold heading, a one-line English caption, and a precise visual element.

1. heading: "Scene Setup", caption: "A doorway, window, and arch can create a natural frame around the main subject.", visual: front-facing simplified street scene with one centered subject standing inside layered architectural openings; show outer wall, rectangular doorway, inner window, and background corridor as nested shapes; add subtle guide lines indicating the frame-within-frame concept.

2. heading: "Wide Angle 24 mm", caption: "A wide lens includes more surroundings, making the frame feel spacious and environmental.", visual: comparison panel showing the same subject inside the doorway frame; render broad field of view, more visible side walls, floor, ceiling, and extra negative space; use a small lens icon labeled 24 mm and a wide viewing cone diagram.

3. heading: "Standard 50 mm", caption: "A standard lens balances subject size and surrounding frame for a natural perspective.", visual: same scene from the same camera position with medium crop; doorway and inner window still visible but tighter around the subject; include a 50 mm lens icon and a moderate viewing cone diagram.

4. heading: "Telephoto 85 mm", caption: "A longer lens tightens the composition and emphasizes the layered frame around the subject.", visual: same scene with compressed perspective and tighter crop; doorway edges and inner frame appear closer together around the subject; reduce visible surroundings; include an 85 mm lens icon and a narrow viewing cone diagram.

5. heading: "Best Use", caption: "Place the subject inside a clear opening and keep the frame shape uncluttered for stronger focus.", visual: distilled composition diagram with check marks beside a clean centered subject, visible frame edges, balanced spacing, and simple background; include small avoid icons for clutter crossing the frame and subject touching frame edges.

Connect all panels with thin blue arrows and dotted alignment lines to show progression from setup to focal length comparison to final guidance. Add a bottom comparison strip with three small crop thumbnails labeled "24 mm", "50 mm", and "85 mm" showing how the framed subject changes size and surrounding context. Include a compact legend with exact labels: "Outer frame", "Inner frame", "Subject", "Negative space", and "Field of view". Visual style: minimal flat technical infographic, cool blue and cream palette with soft slate accents, calm precise editorial mood, geometric shapes, simple vector diagrams, consistent line weights, high clarity, magazine-grade editorial illustration, vector-clean lines, no photographic textures.

All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Accurate technical guidance. No real camera-brand logos.
