The salt-crusted lens cloth in my pocket tells the story of three intensive days filming along the Pacific Coast Highway. As a travel photographer who has logged thousands of flight hours across six continents, I approached this coastal highway project knowing the environment would test every capability of my equipment.
What I didn't anticipate was the electromagnetic interference challenge that emerged during my second morning of shooting—and how a straightforward adjustment transformed a potentially frustrating situation into one of my most productive aerial sessions.
The Assignment: Capturing Highway Dynamics Against Ocean Vistas
My client needed sweeping aerial footage showcasing the dramatic intersection of engineered infrastructure and natural coastal beauty. The brief called for hyperlapse sequences, tracking shots of vehicles navigating serpentine curves, and static compositions emphasizing the highway's integration with the rugged shoreline.
The Air 3S was my tool of choice for this assignment. Its Medium Tele Camera capability offered the compression I needed to stack visual layers—foreground highway, midground cliffs, background ocean horizon—into cohesive compositions.
Expert Insight: When filming linear infrastructure like highways, the medium telephoto perspective eliminates the distortion that wider lenses introduce. This maintains the authentic proportions of road curves and prevents the "stretched" appearance that can make professional footage look amateurish.
Day One: Establishing Shots and System Confidence
The first morning delivered ideal conditions. Light offshore winds, scattered clouds providing natural diffusion, and minimal traffic allowed me to focus on establishing my shooting positions.
I programmed several Waypoint flying routes along a three-mile stretch, creating repeatable flight paths I could execute during optimal lighting windows. The Air 3S stored these routes flawlessly, and I completed twelve separate flights without a single technical concern.
Initial Performance Observations
| Performance Metric | Day One Results | Notes |
|---|---|---|
| Average Flight Duration | 42 minutes | Conservative flying, frequent hovering |
| Signal Strength | Full bars at 1.2km | Clear line of sight |
| Obstacle Avoidance Triggers | 3 instances | Seabirds, cliff proximity |
| Image Quality | 48MP RAW files | Excellent detail retention |
| Wind Resistance | Stable in 15mph gusts | Minimal drift compensation needed |
The omnidirectional sensing system earned its reputation during these initial flights. Twice, seabirds approached the aircraft with apparent territorial intent. The Air 3S detected these moving obstacles and executed smooth evasive adjustments without interrupting my recording.
Day Two: The Electromagnetic Interference Challenge
Morning two began promisingly. I launched from a new position approximately 800 meters south of my previous location, planning to capture sunrise light hitting the cliff faces.
Within three minutes of flight, I noticed intermittent signal warnings on my controller display. The Air 3S maintained stable flight, but the transmission quality fluctuated in ways I hadn't experienced the previous day.
Identifying the External Factor
I landed and assessed the environment. The critical difference between this launch point and my Day One positions became immediately apparent: a high-voltage transmission line corridor ran parallel to the highway, approximately 200 meters inland from my current location.
These power lines, carrying electricity from a coastal generation facility, were producing electromagnetic interference that affected the communication link between my controller and the aircraft.
The Air 3S itself remained completely stable throughout this experience. Its robust transmission system continued operating—the interference simply required me to optimize my settings for this specific electromagnetic environment.
The Simple Adjustment That Restored Perfect Connectivity
I accessed the transmission settings and manually selected a different frequency channel. The Air 3S offers multiple channel options precisely for situations like this, where environmental electromagnetic factors require user optimization.
After switching from the auto-selected channel to a manually chosen alternative, signal strength returned to full capacity. I completed the remaining flights that morning without any further connectivity fluctuations.
Pro Tip: Before launching in any new location, scan for potential electromagnetic interference sources. Power lines, radio towers, military installations, and even large metal structures can affect transmission quality. The Air 3S provides the tools to adapt—you simply need to use them proactively.
Mastering Coastal Highway Footage: Technical Approaches
With connectivity optimized, I focused on capturing the footage my client needed. The Air 3S excelled across multiple shooting modes.
Subject Tracking for Vehicle Sequences
Using ActiveTrack, I followed individual vehicles through curved highway sections. The system maintained lock on moving subjects even when they temporarily disappeared behind rock outcroppings.
Spotlight mode proved particularly effective for shots where I wanted the camera to remain fixed on a specific vehicle while I manually controlled the aircraft's position. This created dynamic parallax effects as the drone moved laterally while the subject stayed centered.
QuickShots for Efficient B-Roll
The QuickShots presets generated professional-quality transitional footage with minimal setup time. I particularly favored the spiral and rocket modes for revealing shots that started tight on highway details before pulling back to expose the broader coastal context.
Hyperlapse Sequences
Coastal highways demand hyperlapse treatment. The compression of time transforms ordinary traffic flow into mesmerizing visual rhythms.
I programmed Hyperlapse sequences during golden hour, capturing the transition from daylight to headlight-illuminated evening traffic. The Air 3S maintained rock-solid positioning throughout these extended automated flights, producing smooth footage that required zero stabilization in post-production.
Color Science: Why D-Log Was Essential
Coastal environments present extreme dynamic range challenges. Bright ocean reflections, deep cliff shadows, and the variable luminance of vehicle surfaces create scenes that exceed the capture capability of standard color profiles.
I shot exclusively in D-Log color profile throughout this project. This flat, log-encoded format preserved approximately two additional stops of dynamic range compared to standard profiles.
D-Log Workflow Benefits
- Retained highlight detail in white vehicle surfaces and ocean foam
- Preserved shadow information in cliff face textures and vegetation
- Provided maximum flexibility for color grading to match client brand guidelines
- Eliminated the crushed blacks and blown highlights that plague coastal footage shot in standard profiles
The 48MP sensor captured sufficient detail that I could deliver both video footage and high-resolution still frames extracted from the same flights—maximizing production value from each battery cycle.
Common Pitfalls: What Coastal Highway Pilots Must Avoid
User Errors That Compromise Results
Ignoring wind patterns: Coastal areas experience thermal shifts throughout the day. Morning offshore winds often reverse to onshore patterns by afternoon. Plan flight times accordingly.
Underestimating salt exposure: Salt spray travels farther than most pilots realize. I clean my Air 3S sensors and gimbal after every coastal session, preventing corrosive buildup.
Neglecting pre-flight environmental assessment: As my electromagnetic interference experience demonstrated, launching without surveying the area for potential signal obstacles creates avoidable complications.
Overconfidence in obstacle avoidance: While the omnidirectional sensing system performs excellently, it cannot predict every scenario. Seabirds, kites, and other aerial objects require pilot awareness beyond automated systems.
Environmental Risks Beyond Pilot Control
- Sudden fog banks that reduce visibility to unsafe levels
- Rogue waves that can reach surprising heights during certain tidal conditions
- Thermal updrafts along cliff faces that create unpredictable turbulence zones
- Wildlife protection zones that may restrict flight operations seasonally
Final Results and Client Delivery
The three-day shoot produced over 180 minutes of usable footage and 2,400 still frames. The Air 3S performed flawlessly once I addressed the electromagnetic interference through proper channel selection.
My client received a comprehensive asset library that included:
- 12 hyperlapse sequences ranging from 15 to 45 seconds each
- 8 tracking shots following vehicles through signature highway curves
- 24 establishing compositions showcasing the highway-ocean relationship
- 6 golden hour sequences capturing the transition from day to evening traffic
The 45-minute flight time meant I could capture complete golden hour sessions on single batteries—a capability that directly translated to more footage and fewer interruptions during critical lighting windows.

Frequently Asked Questions
How does electromagnetic interference from power lines affect drone operations?
High-voltage transmission lines emit electromagnetic fields that can interfere with the radio frequency communication between your controller and aircraft. The Air 3S handles this by offering multiple transmission channels. When you notice signal fluctuation near power infrastructure, manually selecting an alternative channel typically resolves the issue immediately. The aircraft itself remains completely stable—only the communication link requires optimization.
What wind speeds are safe for coastal highway filming with the Air 3S?
The Air 3S maintains stable flight in sustained winds up to approximately 24 mph with gusts somewhat higher. Coastal environments often produce variable conditions, so I recommend launching only when sustained winds remain below 18 mph to ensure smooth footage quality. The aircraft will continue flying safely in stronger conditions, but gimbal compensation becomes visible in footage, reducing professional quality.
Should I use obstacle avoidance when filming moving vehicles on highways?
Absolutely. Keep omnidirectional sensing active during all highway filming operations. While you're focused on framing and composition, the system monitors for unexpected obstacles including birds, other aircraft, and terrain features. The sensing system has prevented multiple potential incidents during my coastal shoots, reacting faster than human reflexes to approaching objects.
