# 07 — Camera and Shot Grammar ## 1. Camera first principles A camera does not merely record an object. It establishes a relationship among subject, world, audience, and time. ```text SHOT = subject state + camera position + optical state + framing + composition + focus + exposure + movement + duration + performance/blocking + sound relation + narrative function + continuity constraints ``` A shot should be selected because of what it lets the audience perceive—not because its name appears on a shot list. ## 2. Complete camera-dimension vector ```text CameraVector = { subject, subject_count, shot_size, azimuth, elevation_angle, camera_height, roll, subject_distance, focal_length, sensor_or_format, field_of_view, perspective, aperture, depth_of_field, focus_distance, focus_behavior, exposure_time_or_shutter, frame_rate, ISO_or_gain, white_balance, composition, headroom, lead_room, look_room, horizon, screen_direction, movement_translation, movement_rotation, movement_path, movement_speed, movement_acceleration, stabilization, blocking, occlusion, foreground, background, duration, entry_state, exit_state, story_function, continuity_links } ``` ## 3. Shot-size grammar Shot size is measured relative to the story subject, not only a human body. | Token | Human reference | Primary perceptual use | |---|---|---| | `EXTREME_WIDE` | person very small or absent | geography, scale, isolation, systems | | `VERY_WIDE` | full body with dominant environment | place and movement | | `WIDE_FULL` | full body | blocking and physical action | | `MEDIUM_FULL` | knees/thighs upward | action plus expression | | `COWBOY` | mid-thigh upward | hands/objects plus face | | `MEDIUM` | waist upward | conversational balance | | `MEDIUM_CLOSE` | chest/shoulders upward | thought and expression | | `CLOSE` | face or one object dominates | emotion, importance, detail | | `BIG_CLOSE` | face tightly framed | intense interior state | | `EXTREME_CLOSE` | eye, mouth, texture, component | sensation, evidence, abstraction | | `INSERT` | object/action detail | proof, mechanism, continuity | | `MACRO` | tiny subject magnified | hidden structure, texture | Relational framings: ```text SINGLE TWO_SHOT THREE_SHOT GROUP OVER_THE_SHOULDER DIRTY_SINGLE CLEAN_SINGLE PROFILE_PAIR POV SUBJECTIVE REACTION CUTAWAY MASTER ``` ## 4. Horizontal angle or azimuth ```text FRONTAL 0° SLIGHT_THREE_QUARTER 15–30° THREE_QUARTER 30–60° PROFILE ~90° REAR_THREE_QUARTER 120–150° REAR ~180° ``` Interpretive tendencies are context-dependent: ```text frontal → direct address, confrontation, symmetry three-quarter → dimensionality, natural conversation profile → observation, opposition, graphic silhouette rear → withholding identity, following, alienation, point of departure ``` Do not treat these tendencies as universal meanings; performance, lens, movement, light, and sequence can reverse them. ## 5. Vertical angle and camera height Vertical angle: ```text BIRD_EYE / TOP_DOWN STEEP_HIGH HIGH EYE_LEVEL LOW STEEP_LOW WORM_EYE ``` Camera height: ```text ground knee waist chest eye above-head overhead aerial ``` Angle and height are separate. A camera can be high but level, or low and tilted upward. ## 6. Roll and horizon ```text LEVEL SUBTLE_CANT DUTCH_ANGLE FULL_ROLL DYNAMIC_ROLL ``` Rule: ```text IF roll communicates instability or transition THEN establish a prior stable reference or a visible physical motivation. IF the horizon changes unintentionally between interview angles THEN correct or treat as a continuity failure. ``` ## 7. Optical grammar ### Focal-length role bands Exact field of view depends on sensor size; store both focal length and sensor/format. ```text ULTRA_WIDE WIDE NORMAL SHORT_TELEPHOTO TELEPHOTO SUPER_TELEPHOTO MACRO_OR_SPECIALTY ``` Perceptual variables: ```text field_of_view camera_subject_distance perspective_expansion_or_compression facial rendering background scale edge distortion focus falloff minimum focus flare breathing anamorphic characteristics ``` First-principle rule: ```text Perspective is primarily controlled by camera position. Focal length selects the field of view from that position. ``` ### Specialty optics ```text ANAMORPHIC TILT_SHIFT PROBE FISHEYE SPLIT_DIOPTER DIOPTER SOFT_FOCUS VINTAGE MIRROR_OR_PRISM ``` Use specialty optics only when the optical behavior supports a named narrative or visual-system function. ## 8. Focus grammar ```text focus_subject focus_distance near_limit far_limit depth_of_field focus_transition transition_speed focus_priority tracking_confidence intentional_defocus ``` Focus operations: ```text STATIC_FOCUS CONTINUOUS_TRACK RACK_FOCUS SNAP_FOCUS PULL_TO_REVEAL DEFOCUS_TRANSITION DEEP_FOCUS SELECTIVE_FOCUS SPLIT_FOCUS ``` Rules: ```text IF narrative ownership transfers between planes THEN rack focus may make that transfer visible. IF spatial causality requires simultaneous foreground and background comprehension THEN prefer deeper focus, blocking, or split-focus treatment. IF focus hunting draws attention without meaning THEN stabilize, replace, or mark technical failure. ``` ## 9. Exposure and temporal capture ```text aperture shutter_time_or_angle ISO_or_gain ND frame_rate capture_speed_ratio highlight_headroom shadow_noise motion_blur flicker_risk ``` Temporal capture states: ```text REAL_TIME OVERCRANKED_SLOW_MOTION UNDERCRANKED_FAST_MOTION TIMELAPSE HYPERLAPSE STOP_MOTION VARIABLE_FRAME_RATE HIGH_SHUTTER_STACCATO LONG_EXPOSURE_BLUR ``` Frame rate and shutter must be planned with artificial-light flicker, delivery cadence, motion character, and slow-motion intent. ## 10. Camera movement grammar ### Translational movement ```text PUSH_IN / DOLLY_IN PULL_OUT / DOLLY_OUT TRUCK_LEFT_RIGHT PEDESTAL_UP_DOWN CRANE_UP_DOWN TRACK_FOLLOW LEAD LATERAL_TRACK DIAGONAL_MOVE ARC / ORBIT SPIRAL AERIAL_TRANSLATION HAND_CARRY_TRANSLATION ``` ### Rotational movement ```text PAN TILT ROLL WHIP_PAN WHIP_TILT ``` ### Optical or computational movement ```text ZOOM_IN ZOOM_OUT DOLLY_ZOOM DIGITAL_PUNCH REFRAME PARALLAX_COMPOSITE VIRTUAL_CAMERA ``` ### Movement path ```text LINEAR CURVED CIRCULAR S_CURVE RANDOM FOLLOW_SUBJECT LEAD_SUBJECT REVEAL_FROM_OCCLUSION PASS_THROUGH RISE_AND_REVEAL DESCEND_AND_CONCEAL ``` ### Movement profile ```text start_velocity end_velocity peak_velocity acceleration deceleration easing smoothness shake_amplitude shake_frequency operator_latency ``` ### Stabilization state ```text LOCKED_OFF TRIPOD_HEAD DOLLY SLIDER JIB_OR_CRANE GIMBAL STEADICAM HANDHELD_CONTROLLED HANDHELD_RAW SHOULDER BODY_RIG VEHICLE_RIG DRONE VIRTUAL ``` ## 11. Movement-function rules ```text IF information grows more intimate or consequential THEN a motivated push-in may compress audience distance. IF context or consequence expands beyond the subject THEN a pull-out or reveal may expose the larger system. IF two entities must be compared without a cut THEN pan, rack focus, lateral move, or blocking can transfer attention. IF the audience should discover information with the subject THEN follow or reveal rather than pre-show the answer. IF movement has no subject, destination, reveal, rhythm, or emotional function THEN prefer static framing. IF motion intensity exceeds story intensity THEN reduce speed, amplitude, axes, or frequency. ``` ## 12. Composition grammar ### Spatial organization ```text CENTERED RULE_OF_THIRDS SYMMETRICAL ASYMMETRICAL_BALANCE GOLDEN_SECTION DIAGONAL TRIANGULAR FRAME_WITHIN_FRAME LAYERED_DEPTH FLAT_GRAPHIC NEGATIVE_SPACE EDGE_TENSION REPETITION_PATTERN LEADING_LINES VANISHING_POINT ``` ### Subject-placement variables ```text headroom look_room lead_room body_crop joint_crop_safety horizon_position center_of_mass visual_weight figure_ground_separation foreground_occlusion background_tangent ``` ### Depth layers ```text foreground near_subject primary_subject secondary_subject background far_background ``` Each layer can carry information, motion, framing, contrast, or concealment. ## 13. Blocking grammar ```text BLOCKING = subject position + orientation + posture + gaze + path + speed + interaction + prop relation + camera relation + light relation ``` Blocking operations: ```text ENTER EXIT CROSS APPROACH RETREAT CIRCLE STOP TURN SIT STAND REVEAL CONCEAL HAND_OFF POINT LOOK TOUCH SEPARATE CONVERGE ``` Rule: ```text Prefer motivated subject movement over compensatory camera movement when the subject action itself carries the story change. ``` ## 14. Screen-direction and spatial continuity Track: ```text axis_of_action camera_side_of_axis subject_screen_position movement_direction eyeline_vector entrance_exit_direction geographic orientation ``` Continuity operations: ```text MAINTAIN_AXIS CROSS_AXIS_ON_CAMERA CROSS_AXIS_WITH_NEUTRAL_SHOT CROSS_AXIS_WITH_MASTER_RESET INTENTIONAL_DISORIENTATION MATCH_EYELINE MATCH_MOVEMENT MATCH_POSITION ``` Rule: ```text IF spatial comprehension matters THEN crossing the axis requires visible motivation or reorientation. IF disorientation is the intended audience state THEN continuity may be violated deliberately, but tag the purpose and duration. ``` ## 15. Coverage grammar Minimum dramatic or documentary coverage can include: ```text ESTABLISHING MASTER PRIMARY_ACTION ALTERNATE_SIZE OPPOSING_ANGLE REACTION INSERT CUTAWAY TRANSITION_IN TRANSITION_OUT ROOM_TONE_OR_WILD_SOUND ``` Coverage planner equation: ```text RequiredCoverage = story functions + continuity dependencies + compression needs + performance uncertainty + format variants + repair allowance ``` Coverage is not maximized blindly. Extra coverage has capture, review, storage, and continuity costs. ## 16. Camera motivation taxonomy A shot or camera change should perform at least one function: ```text ORIENT REVEAL CONCEAL EMPHASIZE COMPARE CONNECT ISOLATE ALIGN DISTANCE INTENSIFY RELIEVE FOLLOW ANTICIPATE VERIFY ABSTRACT TRANSITION RHYTHM SPECTACLE ``` Store the motivation with the shot plan. ## 17. Generated-shot continuity keys For generated video, lock: ```text character identity and wardrobe body and prop topology camera side and lens family subject screen direction light direction and time of day weather and atmosphere set geometry start pose and end pose movement vector frame rate and motion character color pipeline ``` A generated shot without an entry and exit state is difficult to edit reliably. ## 18. Camera LAKA variations For one base shot: ### Baseline ```text same subject, size, angle, lens family, movement, and duration ``` ### Minor ```text small framing adjustment slower move shallower/deeper focus slight azimuth shift ``` ### Major ```text new size or angle static becomes moving new foreground layer new subject relation ``` ### Structural ```text single becomes sequence objective becomes POV continuous coverage becomes montage new axis or blocking design ``` ### Paradigm ```text literal scene becomes abstract visualization human viewpoint becomes object/system viewpoint observational camera becomes subjective memory ``` ## 19. Camera failure modes ```text ANGLE_WITHOUT_MOTIVATION PERSPECTIVE_MISMATCH EYE_LINE_ERROR AXIS_CONFUSION UNSAFE_BODY_CROP BACKGROUND_TANGENT FOCUS_WITHOUT_OWNER MOTION_WITHOUT_DESTINATION UNCONTROLLED_HORIZON LENS_STYLE_DRIFT CAMERA_OUTPACES_EMOTION INADEQUATE_HANDLES MISSING_ESTABLISHMENT MISSING_REACTION GENERATED_ENTRY_EXIT_MISMATCH ``` ## 20. Shot acceptance test ```text What must the audience perceive in this shot? Why this size, position, lens, and duration? What changes from entry to exit? How does the shot connect spatially and temporally to neighbors? Does movement have a subject and destination? Does focus identify the information owner? Can the shot survive required aspect-ratio versions? Are performance, lighting, sound, and provenance usable? ```
