Capstone: planning a specialty shoot

This capstone brings the course together. You will plan a short specialty sequence that combines large-format capture, aerial work, a drone, a suspended camera, underwater shots and a cold-weather location. The aim is not to master every technique yourself but to show that you can turn a director's intent into a plan that specialists can execute safely, on schedule and on budget, with images that match the rest of the film. Work through each section, then assemble your own plan for a sequence of your choosing using the template at the end.

The brief

The film is a drama about a search-and-rescue volunteer. The climactic sequence, about two and a half minutes on screen, follows her across a frozen mountain lake at first light to reach a person who has fallen through the ice. The director wants the audience to feel the vast, indifferent landscape, then the claustrophobic danger under the ice, then the relief of the rescue. The film is planned for an IMAX release with expanded-ratio sequences, and this sequence will open up to 1.90:1 on IMAX screens.

The location is a lake in the Rocky Mountains of Colorado, at about 9,000 ft (2,700 m), in February, where dawn temperatures are often around −4 °F (−20 °C).

The director's shot list includes: a high aerial over the mountains revealing the lake; a lower drone move that follows the volunteer running across the ice; a fast cable-cam move skimming the surface beside her; underwater shots looking up through the ice at the hole and the struggling person; and close coverage on the ice for the rescue.

Step 1: match methods to shots

Methods for each shot in the sequence
ShotStory purposeMethodWhy this method
High mountain revealVast, indifferent scaleHelicopter with gyro-stabilized head and large-format cameraAltitude, speed and range in a short dawn window, carrying the main camera family
Following the runUrgency and isolationHeavy-lift drone with cinema cameraLow, flexible path over the ice, cheaper than the helicopter for low work
Skimming beside herSpeed and dangerPoint-to-point cable cam along the shoreRepeatable, fast, low over the ice, and safer than a drone close to the actor
Under the iceClaustrophobiaStudio tank with an ice-set ceiling, plus a short open-water ice dive for platesControl of light, temperature and safety; real ice for authenticity in selected shots
Rescue on the iceRelief and human contactMain unit handheld and dolly on the ice, large-format cameraPerformance-led coverage on a safe, assessed ice surface

The plan moves the most dangerous underwater work into a controlled tank, using the real lake only for short, supervised plate dives. That is the kind of decision a DP should propose early.

Step 2: format, lenses and matching

  • Camera: a 65 mm digital camera for main unit, aerial and drone where payload allows, recording a mode that IMAX accepts for its expanded ratio; a full-frame camera of the same family for the cable cam if weight requires it.
  • Lenses: large-format primes for main unit; a lighter large-format zoom or primes for aerial and drone, within payload limits.
  • Frame lines: 1.90:1 and 2.39:1 loaded on every camera, with action kept in the common area.
  • Exposure and color: one show LUT, the same recording format and the same white balance approach across units; snow exposed brighter than middle gray with highlight detail protected.
  • Frame rate and shutter: 24 fps, 180° shutter, with ND filters to hold the shutter in bright snow.

Worked problem

Equivalent lens for the cable cam

The main unit frames the run with a 90 mm lens on a 65 mm sensor 54.1 mm wide. The cable cam can only carry a full-frame camera 36 mm wide. What focal length matches the main unit framing from the same distance?

Show solution
  1. Ratio: 36 ÷ 54.1 ≈ 0.665.
  2. Focal length: 90 × 0.665 ≈ 60 mm.

Answer: About 60 mm on the full-frame camera. The DP checks depth of field too: to match T4 on the 65 mm sensor, the full-frame camera would use about T2.8.

Step 3: safety and risk assessment

Key hazards and controls for the sequence
HazardLikelihood (1 to 5)Severity (1 to 5)ScoreMain controls
Ice failure under crew or equipment2510Ice thickness testing by qualified ice safety specialists, load limits, safety lines, rescue team on standby
Cold injury to cast and crew4312Warm-up shelters, rotations, clothing, medic, short takes for actors
Aircraft accident or low-flying risk155Experienced film aviation operator, low-flight approvals, pilot authority, weather limits
Drone loss of control near people248Certified pilot and observer, exclusion zones, battery management in cold
Cable cam failure155Engineered rig, inspections, exclusion zone under the path, wind limits
Diver incident in cold water2510Tank for most work, dive supervisor, ice-diving specialists, tethered divers, short dives
Avalanche on surrounding slopes2510Avalanche specialist assessment, restricted areas, daily forecast checks

Scores of 10 or more need specific controls approved before work starts. The production safety team, not the DP, owns the plan, but the DP's shot requests shape it, and the DP agrees to keep shots within the controls.

Step 4: equipment and people in the cold

Worked problem

Battery planning for the drone in the cold

The heavy-lift drone uses battery sets that give 15 minutes of flight at 20 °C. At −20 °C, the drone team expects only about 60 % of the flight time, even with warmed batteries. The plan needs 10 flights of useful filming time, each needing 8 minutes. How many flights and battery sets are needed?

Show solution
  1. Cold flight time: 15 × 0.60 = 9 minutes per set, which barely covers an 8-minute flight with a reserve.
  2. To keep a safe reserve, plan 6-minute filming segments, so 80 minutes of filming needs 80 ÷ 6 ≈ 14 flights.
  3. With warming and charging limited on location, plan one set per flight plus spares: about 16 sets, or fewer if a heated charging station can recharge sets during the day.

Answer: About 14 shorter flights and around 16 battery sets, or a heated charging tent with generator power. The cold forces shorter, rehearsed moves.

  • Crew: cold-weather clothing standards, warm-up shelters within a short walk, rotation schedules and hot food.
  • Cast: a costume plan with hidden warm layers, a warming tent beside the set and limits on time in the cold.
  • Equipment: heated battery storage, cold-rated cables, condensation control between set and shelters.
  • Altitude: at mountain altitudes the drone's lift and the helicopter's performance fall, so payloads and flight plans are adjusted.

Step 5: schedule

  • Day 1: rig the cable cam, test ice, set up shelters and power; drone tests; helicopter positioning.
  • Day 2, dawn: helicopter reveal shots in the first 45 minutes of good light, then drone shots; afternoon: cable-cam rehearsals and takes.
  • Day 3: main unit rescue coverage on the ice; weather-hold day if needed.
  • Days 4 and 5 (studio): tank work under the ice set, with the underwater unit.
  • One plate dive day at the lake, scheduled with the ice-diving team, with a backup day.
A schedule chart with columns for Day 1 to Day 5 and a dive day. Bars show rigging and ice tests on Day 1, the dawn helicopter reveal, drone shots and cable cam takes on Day 2, the rescue on the ice on Day 3, two tank days under the ice set and a plate dive day at the lake.
The capstone schedule. Dawn aerials, cold-weather work and tank days are grouped, with weather holds kept free.

Worked problem

Light window for the aerial reveal

Sunrise is at 7:45, and the director wants the reveal in the warm, low light from 15 minutes before to 30 minutes after sunrise. Each helicopter pass takes 4 minutes including repositioning. How many passes fit, and how should the schedule protect them?

Show solution
  1. Window: 7:30 to 8:15, which is 45 minutes.
  2. Passes: 45 ÷ 4 ≈ 11.
  3. Pre-flight checks, briefings and positioning must be done before 7:30 so the window is used for filming.

Answer: About 11 passes. The helicopter should be airborne and in position before 7:30, with a backup morning in case of weather.

Step 6: data

Worked problem

Storage for the sequence

Across five shooting days the units expect to record a total of 9 hours of material at about 2.6 TB per hour (uncompressed 65 mm raw), with three copies required. How much storage is needed, and what would change with a 3:1 compressed raw option?

Show solution
  1. One copy: 9 × 2.6 = 23.4 TB.
  2. Three copies: 3 × 23.4 = 70.2 TB.
  3. With 3:1 compression: 70.2 ÷ 3 ≈ 23.4 TB for three copies.

Answer: About 70 TB uncompressed or about 23 TB with 3:1 compressed raw. The DP and post supervisor should test whether compressed raw holds detail in snow and dark water before choosing.

Step 7: budget

Weather contingency15 % of the above25,485
Total195,385

Worked problem

Checking the budget arithmetic

Confirm the subtotal before contingency and the 15 % contingency in the table.

Show solution
  1. Subtotal: 20,400 + 14,000 + 16,500 + 24,000 + 36,000 + 15,000 + 22,500 + 12,000 + 9,500 = 169,900.
  2. Contingency: 0.15 × 169,900 = 25,485.
  3. Total: 169,900 + 25,485 = 195,385.

Answer: The subtotal is 169,900, the contingency 25,485 and the total 195,385, all at illustrative rates. A real budget uses quotes from the specialist companies.

Approvals for the US location

  • FAA approvals held by the aviation operator, including a certificate of waiver with a motion picture operations manual for low-level filming, and air traffic coordination if any controlled airspace applies.
  • Part 107 remote pilot certificates, registered drones with Remote ID, and any waivers or LAANC authorizations needed.
  • Permits from the land manager: the US Forest Service or state land agency, or the National Park Service if the lake were in a national park, where drone use would almost certainly not be allowed.
  • A commercial diving plan under OSHA's commercial diving standard for the plate dive.
  • Consultation with tribal governments if the location includes tribal lands or culturally significant sites.

Presenting the plan

When you present a specialty plan to the director and producers, lead with the story and the experience the audience will have, then show how each method serves it, then the safety plan, schedule and budget. Show references and tests where you have them. Be clear about what could change the plan: weather, ice conditions, approvals or test results. Producers trust a DP who shows they have thought about risk and money as carefully as about images.

Template for your own specialty plan

  • The brief: story purpose, screen time, release format and location.
  • Shot list with story purpose for each shot.
  • Method for each shot and the reason for choosing it.
  • Format, lenses, aspect ratios and matching plan.
  • Risk assessment with scores and controls.
  • Equipment and people plan for the environment.
  • Schedule with light windows and weather holds.
  • Data estimate and workflow.
  • Budget with contingency.
  • Approvals and permits for your country and location.

Common mistakes

  • MistakeChoosing the riskiest method because it looks most authentic

    InsteadMove dangerous work into controlled settings where possible and use the real location for selected, supervised shots

  • MistakePlanning drone flights in the cold with warm-weather flight times

    InsteadReduce flight time estimates for cold and altitude and plan shorter, rehearsed segments

  • MistakeScheduling the helicopter to take off at the start of the light window

    InsteadComplete checks, briefings and positioning before the window so it is used for filming

  • MistakePresenting a specialty plan with no contingency

    InsteadInclude weather and risk contingencies and explain what could change the plan

  • MistakeLeaving approvals until the week before the shoot

    InsteadStart aviation, land, diving and community approvals in early prep

Summary and key terms

  • A specialty plan starts from the director's story intent and assigns the most suitable method to each shot.
  • Format, lenses, aspect ratios, exposure and color are matched across units so specialty shots cut with main unit.
  • Risk assessments score hazards and require specific controls for high scores, owned by the production safety team.
  • Cold and altitude reduce battery and aircraft performance, shaping flight plans and equipment lists.
  • Schedules protect light windows and include weather holds and backup days.
  • Data and budgets are estimated from recording hours, copies, quotes and a contingency.
  • Approvals for aviation, land, diving and communities must be secured early for the specific country and location.
