Exposure Triangle Cheat Sheet Style Shallow DOF Infographic

Educational infographic poster titled "Shallow Depth of Field Composition Guide" in portrait layout, designed as an overlay grid examples sheet, with sharp, readable text labels and clean spacing. Create a sketchnote-style educational infographic with accurate technical guidance, high-contrast modern palette, energetic but precise mood, magazine-grade editorial illustration, vector-clean lines, no photographic textures, and absolutely no real camera-brand logos.

Include 6 numbered components arranged in a clear vertical sequence with arrows and dotted guide lines between panels, plus overlay grid examples inside each example frame:

1. heading: "1. What Shallow DOF Means"; caption: "A thin focus zone keeps the subject sharp while foreground and background blur."; visual: central portrait subject in crisp focus, soft blurred city lights behind, faint blurred foreground leaves, a side cutaway focus-plane diagram beside the image, and a rule-of-thirds overlay grid on top of the example frame.

2. heading: "2. Wide Aperture"; caption: "Use a low f-number like f/1.8 to make the depth of field much shallower."; visual: large aperture iris diagram opening wide, comparison mini-panels showing narrow versus wide aperture, bold arrow pointing to the wide opening, and a sample composition frame with overlay grid and strongly blurred background circles.

3. heading: "3. Subject Distance"; caption: "Move closer to the subject to reduce depth of field and increase background blur."; visual: camera icon moving toward a flower or face with three step positions, distance arrows shortening, focus zone becoming thinner, and a grid-overlay example frame showing close-up subject placement on an intersection point.

4. heading: "4. Background Separation"; caption: "Place the subject far from the background so blur appears smoother and stronger."; visual: side-view diagram with subject in front and distant background wall or trees behind, long arrow marking subject-to-background distance, blurred background bokeh sample, and overlay grid example showing subject isolated against negative space.

5. heading: "5. Focal Length Effect"; caption: "Longer lenses can make the background appear larger and more blurred in portraits."; visual: comparison between a short lens and a longer lens, both aimed at the same subject, with the longer-lens panel showing tighter framing and creamier blur, plus a compositional overlay grid in each frame and directional arrows linking the comparison.

6. heading: "6. Composition Checklist"; caption: "Keep the eye or main detail tack sharp and place it carefully on the grid for impact."; visual: sketchnote checklist panel with icons for eye focus, clean background, wide aperture, close distance, and background separation; large sample portrait frame with rule-of-thirds grid, highlighted top-third intersection at the eye, and a small inset showing acceptable blur falloff from sharp subject to soft background.

Add a small side legend with simple icons for aperture, distance, focal length, focus plane, and blur strength, each rendered as neat vector symbols. Use bold black linework, electric cyan, vivid magenta, bright yellow, white, and deep charcoal accents for the high-contrast modern palette. Keep the overall look hand-drawn sketchnote but structurally precise, with annotated arrows, dotted connectors, numbered circles, clean diagram boxes, and crisp editorial hierarchy.

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.
