Camera & Perspective – Detailed Variables

A. Camera Position & Orientation

1. Height / Eye-Level

   • Waist/Low: Looking slightly upward at subjects, emphasizing their height.

   • Eye-Level: Neutral vantage, often considered the most natural.

   • High/Overhead: Viewing from above, can flatten depth or reveal ground patterns.

2. Horizontal Orientation

   • Front-Facing: Camera directly in front of the subject(s), capturing frontal details (face, torso).

   • Side (Profile): Perfectly perpendicular to the subject’s direction of movement or stance.

   • Three-Quarter: Partial front or rear angle, often used for a balanced sense of depth.

   • Rear View: From behind, focusing on back details or silhouettes.

3. Distance from Subject

   • Close-Up: Detailed facial expression, small portion of the environment.

   • Medium Shot: Waist-up or half-body, common for capturing gestures and moderate environment context.

   • Full Shot: Entire body visible, shows posture, clothing, plus some background.

   • Long Shot: Subject is smaller in frame, environment is more prominent.

B. Lens & Field of View

1. Wide Angle (Short Focal Length)

   • Expands the sense of space, can exaggerate distance or cause slight distortion.

   • Good for showcasing environment but can distort subject proportions if used too close.

2. Standard / Medium (Neutral Focal Length)

   • Mimics human vision, minimal distortion.

   • Often best for balanced portraits or runway demos.

3. Telephoto (Long Focal Length)

   • Compresses the scene, flattening depth.

   • Potentially better for focusing on a subject while blurring the background, but less environment context.

4. Depth of Field

   • Shallow: Subject in focus, background blurred, emphasizing the subject.

   • Deep: Both subject and background in focus—useful for large, detailed environments or multiple points of interest.

C. Framing & Composition

1. Rule of Thirds / Centered

   • Placing the subject at a third-line intersection or dead center.

   • Centered framing often suits symmetrical or formal presentations (like a runway).

2. Horizon Line

   • If outdoors, deciding where the horizon sits in the frame can drastically change the scene’s look.

   • For indoor or studio setups, horizon line might be irrelevant or replaced by a “floor line.”

3. Negative Space

   • Extra space around the subject for minimalistic scenes or emotional emphasis.

   • Balanced with subject scale to avoid overshadowing or crowding.

D. Camera Motion (If Any)

1. Static / Locked Off

   • Camera does not move; subject traverses the frame.

   • Easiest for consistent AI rendering—each frame has minimal perspective changes.

2. Panning / Tilting

   • Horizontal or vertical pivot from a fixed point, often following the subject.

   • Risk of complexity if the AI must redraw environment from shifting angles.

3. Tracking / Dolly

   • Camera physically moves parallel to subject or forward/back.

   • Enhances depth changes but can complicate the rendering. Use carefully if seeking stable results.

4. Zoom

   • Changing focal length mid-shot. Usually best to keep it subtle, or avoid altogether for reliability in AI outputs.

E. Perspective & Depth

1. Vanishing Points

   • In architectural or street scenes, lines recede to a horizon or corner of frame.

   • Make sure the vantage complements the environment’s geometry—contradictory instructions can cause distortions.

2. Foreground, Midground, Background

   • If you want a layered environment, specify if the subject is in the foreground while mid/background remain simple or more detailed.

3. Height & Scaling

   • Clarify subject scale relative to environment. If the subject is large, the camera may have to be positioned further back.

F. Practical AI Prompt Considerations

1. Simplicity

   • Provide only one or two angles or movements to keep AI results consistent.

   • Avoid contradictory statements like “camera remains static while panning around the subject.”

2. Stable Shots

   • For runway or demonstration style, a static camera or minimal movement is recommended—less chance for glitchy transitions.

3. Compositional Priority

   • Define if the focus is the subject (like a figure) or the environment. This impacts whether you do a full-body shot or a smaller subject in a wide environment.

4. Depth of Field

   • If you want a crisp subject and blurred background, specify “shallow depth of field.” If environment detail is crucial, request a “deep focus.”

Why Camera & Perspective Matter

• It sets the viewer’s relationship to the subject—height, distance, angle, and lens choice drastically change the aesthetic.

• Ensures visual consistency across a series of clips if you keep the same vantage for all subjects or scenes.

• Minimizes confusion for the AI by being explicit: “Camera is front-facing, static, at waist height, the subject fully in frame” is more reliable than layered instructions.
