Settings first: f/8, ISO 100, 20-second exposure, manual focus set to infinity. That is your starting point for nighttime lightning photography. Write it down, tape it to your tripod, commit it to memory. From these four numbers, you can adjust for any storm, any distance, any bolt brightness. Everything else in lightning photography — composition, timing, safety, gear — flows from understanding why these settings work and when to change them.
Lightning photography sits at the intersection of preparation and chance. You cannot direct a bolt of lightning. You cannot ask it to strike again in the same spot with better framing. What you can do is position yourself wisely, set your camera to capture whatever the sky delivers, and fire enough exposures that probability works in your favor. On a night with active lightning, a photographer running continuous 20-second exposures over two hours captures roughly 360 frames. Even a modest storm with a bolt every 2 to 3 minutes means you have 40 to 60 opportunities. You do not need luck. You need patience and the right settings.
What You Need
Camera body: Any camera capable of manual exposure and exposures of 15 seconds or longer. Bulb mode (B) is valuable for exposures beyond 30 seconds. A camera with an electronic shutter option can reduce vibration during long exposures.
Lens: A wide-angle lens in the 14-35mm range is the workhorse for lightning photography. Wider fields of view capture more sky, increasing your odds of catching a bolt within the frame. A 16mm lens on a full-frame body covers roughly 107 degrees horizontally. A 24mm covers about 74 degrees. The wider you go, the more sky you include, but individual bolts will appear smaller.
Sturdy tripod: Non-negotiable. Any movement during a 20-second exposure ruins the shot. Use a tripod rated for at least twice your camera and lens weight. Extend the thickest leg sections first. Do not extend the center column if it is windy. Hang your camera bag from the center hook for additional stability.
Intervalometer or remote shutter release: An intervalometer automates continuous shooting by firing a new exposure immediately after the previous one ends. This hands-free approach means you are not touching the camera between shots (which would cause vibration) and you do not miss bolts while pressing the shutter button. Many modern cameras have built-in interval timers that serve the same purpose.
Lightning trigger (optional but powerful for daytime): A device like MIOPS or Pluto Trigger that detects the electromagnetic pulse or light flash from lightning and fires your camera shutter within 1 to 5 milliseconds. Essential for daytime lightning where long exposures are not possible. Prices range from $100 to $300.
Weather radar app: A storm-tracking app with real-time lightning strike maps helps you predict where a storm is heading and when lightning activity is intensifying or fading. This is both a creative tool and a safety tool.
Rain protection: A rain cover or plastic bag for your camera. Lightning storms bring rain, sometimes suddenly. Protect your gear before the first drops fall.
Headlamp with red mode: For navigating your gear in the dark without destroying your night-adapted vision.
Camera Settings Breakdown
Shutter speed: For nighttime lightning, 15 to 30 seconds is the standard range. Longer exposures capture more time, increasing the chance that a bolt fires during your exposure. However, if ambient light is strong (city skyline, full moon, twilight), long exposures will overexpose the scene. At twilight, you might need 4 to 8 seconds. During full darkness with minimal ambient light, you can extend to 30 seconds or use bulb mode for 45 to 60 seconds.
For daytime lightning without a trigger, long exposures are impossible due to the bright ambient light. Neutral density (ND) filters can help — a 10-stop ND filter turns a 1/250s daytime exposure into a 4-second exposure, which might capture a bolt if lightning is very frequent. A lightning trigger is the more reliable daytime solution.
Aperture: Start at f/8. This is a reliable middle ground that captures bolt detail without overexposing close, bright strikes. If a bolt fills a large section of the frame and is blown out (pure white with no internal structure), stop down to f/11 or f/13. If bolts are distant and faint, open to f/5.6. Very distant storms (15+ miles) may require f/4.
ISO: Begin at ISO 100 or 200. Low ISO reduces noise in long exposures and prevents ambient light from overexposing the sky during 20-30 second frames. If bolts are very faint or distant, raise to ISO 400. Rarely will you need to go higher than ISO 800 for lightning work.
Focus: Set manual focus to infinity or slightly before infinity (many lenses focus past infinity). The most reliable method: during twilight, autofocus on a distant object (a building, a cell tower, the horizon) and then switch the lens to manual focus without touching the focus ring. If it is already dark, use live view at maximum zoom on a distant light (a star, a distant streetlamp) and manually focus until it is a sharp point. Once focused, do not touch the focus ring for the rest of the session. Some photographers tape the ring in place with gaffer tape.
Image stabilization: Turn it off. On a tripod with long exposures, image stabilization can introduce micro-vibrations as the system hunts for movement that is not there.
Long exposure noise reduction: Consider turning this off. In-camera long exposure noise reduction works by taking a second “dark frame” of equal length after each shot. This means a 20-second exposure is followed by 20 seconds of processing where you cannot take another photo — 20 seconds during which lightning bolts are going unrecorded. The noise at ISO 100 with a 20-second exposure is minimal on most modern cameras. Turn off LENR and handle noise in post if needed.
Step-by-Step Guide
1. Plan and Position Safely
Safety is the absolute first priority in lightning photography. Lightning kills roughly 20 people per year in the United States and injures hundreds more. No photograph is worth a direct strike or a ground current injury.
The 6-mile minimum rule: Maintain at least 6 miles between you and the active lightning. At 6 miles, a bolt is close enough to fill a wide-angle frame dramatically but far enough that the risk of a strike at your location is low. Use a weather radar app with real-time lightning strike mapping to judge distance. Count the seconds between a visible bolt and its thunder — every 5 seconds equals roughly 1 mile (every 3 seconds equals roughly 1 kilometer). If you count less than 30 seconds, the storm is within 6 miles and you need to reassess your position.
Best positions: Inside a car with the windows up (the metal body acts as a Faraday cage). Under a solid building’s overhang with the storm in front of you. On an enclosed porch. These positions let you shoot through open air while having immediate full cover.
Avoid: Open fields, hilltops, isolated trees, metal fences, bodies of water, and anything that makes you the tallest object in the area. If your hair stands on end or you feel tingling on your skin, lightning is imminent nearby — crouch low immediately.
Scout your location in advance using satellite maps. Look for foreground elements that will add interest: a skyline, a lone tree on a ridge (photographed from a safe distance), a body of water that will reflect the bolts, a highway with car trails.
2. Set Up Your Tripod and Compose
Arrive at your location before the storm reaches peak activity. Set up your tripod on firm ground, not mud that might shift during a long session. Level the tripod head.
Frame your composition wide. You are guessing where bolts will strike, and a wider field of view dramatically increases your capture rate. Aim toward the most active part of the storm — usually the leading edge where the darkest clouds meet the sky.
Include 60 to 70% sky and 30 to 40% ground or foreground. A pure sky shot with no ground reference lacks scale and context. A city skyline, mountain ridge, or even a flat horizon line gives the bolt a sense of place and proportion.
Do not center the horizon. Place it in the lower third for emphasis on the storm, or in the upper third if your foreground is particularly dramatic (a reflective lake, a winding road with light trails).
3. Dial In Your Base Settings
Set your camera to manual mode (M). Input the base settings: f/8, ISO 100, 20 seconds. Set focus to manual and focus at infinity using the method described above.
Take a test exposure. The sky should be dark but not black — you want to see cloud structure and some ambient tone. If the sky is pure black, raise ISO to 200 or open to f/5.6. If the sky is too bright (washed-out clouds, excessive city light pollution), shorten the exposure to 10 to 15 seconds or stop down to f/11.
The goal for your base frame (without lightning) is a slightly dark, moody sky with visible cloud texture and a properly exposed foreground. When a lightning bolt fires during this exposure, it adds its own light to the scene, illuminating the clouds from within and casting light on the landscape below.
4. Shoot Continuous Long Exposures
Connect your intervalometer and program it to fire a new exposure immediately after the previous one ends. Set the interval to 1 second (the minimum gap between exposures) with an unlimited frame count. Press start and step back.
Your camera is now running continuous 20-second exposures with a 1-second gap between each. Over one hour, you will capture approximately 171 frames. Over two hours, roughly 342 frames. Each frame is a 20-second window during which any lightning bolt in your field of view is recorded.
Do not stop the sequence to check images unless you need to adjust settings. Every time you pause to review, you create a gap where a bolt goes unrecorded. Trust the process and review images later.
If you do not have an intervalometer, many cameras offer a built-in interval shooting mode. Set the interval to the minimum above your shutter speed (e.g., 21 seconds for a 20-second exposure) and the total frame count to 999 or unlimited.
5. Adjust for Bolt Brightness and Frequency
After capturing your first few bolts, review them quickly on the LCD (zoom in to check detail):
If bolts are overexposed (solid white with no visible branching structure): Stop down the aperture by one stop — from f/8 to f/11. This reduces both bolt brightness and ambient light. If f/11 is not enough, try f/13 or f/16 for very close, bright strikes.
If bolts are dim and lack punch: Open the aperture to f/5.6, or raise ISO to 200-400. Distant storms (10+ miles) often produce bolts that need this boost.
If multiple bolts fire during a single exposure: The cumulative light from several bolts can overexpose the sky. Shorten the exposure time to 10 or 15 seconds so fewer bolts accumulate per frame. During extremely active storms with bolts every few seconds, 8-second exposures at f/11 may be necessary.
If the storm is moving laterally: Re-aim your composition every 10 to 15 minutes to track the most active region. Storms travel at 20 to 40 miles per hour, so the active zone shifts noticeably over time.
6. Use a Lightning Trigger for Daytime Storms
Daytime lightning is spectacular but cannot be captured with the standard long-exposure method because the bright ambient light makes exposures longer than 1/2 second impossible without extreme ND filtration.
A lightning trigger solves this by detecting the light pulse from a bolt and firing your camera shutter within 1 to 5 milliseconds. Since most lightning strikes consist of multiple return strokes over 200 to 500 milliseconds, the trigger fires in time to capture the later strokes even though it missed the first one.
Setup: Mount the trigger on your camera’s hot shoe or connect it via cable to the remote shutter port. Set the trigger sensitivity to medium. Set your camera to manual mode with settings appropriate for the daylight — typically f/8 to f/11, ISO 100, 1/200s to 1/500s. Enable continuous shooting mode so the trigger fires a burst.
Daytime settings differ from nighttime: You are freezing the bolt with a fast shutter speed rather than accumulating it over a long exposure. The bolt’s brightness must compete with the ambient daylight, so bolts will appear less dramatic in daytime photos than nighttime ones. Underexposing the ambient scene by -1 to -1.5 stops makes the bolt stand out more against the darkened sky.
Point the trigger’s sensor toward the storm. It detects the optical flash from lightning within its field of view. Position the sensor and your lens in the same general direction. Expect some missed bolts — triggers have about a 60 to 80% capture rate depending on bolt distance and angle.
Common Mistakes
Framing too tight. Lightning is unpredictable. A tight frame that shows a beautiful section of cloud will miss bolts that strike 20 degrees to the left. Start wide, capture bolts, and crop in post-processing. You can always crop a wide shot tighter, but you cannot expand a tight shot wider.
Stopping the sequence to check images. The urge to review every few minutes is strong. Resist it. Each pause is a potential missed bolt. Set your intervalometer and let it run for 15 to 20 minutes before checking. The storm will not wait for you to scroll through your LCD.
Forgetting to turn off long exposure noise reduction. This setting doubles your effective shooting time per frame. A 20-second exposure becomes 40 seconds (20 shooting + 20 processing). During the processing half, you miss everything. Turn LENR off for lightning work.
Underestimating ambient light. City glow, moonlight, and twilight all add ambient exposure that accumulates over long exposures. If your sky is washed out and flat, the ambient light is too strong for your current settings. Shorten the exposure or stop down the aperture.
Ignoring safety because the shot is good. Storms move faster than photographers expect. A storm 8 miles away when you set up may be 4 miles away 10 minutes later. Monitor distance continuously. If thunder follows lightning in under 25 seconds, the storm is within 5 miles and closing. Prioritize getting to full shelter.
Using autofocus. In the dark, autofocus hunts and shifts between shots. One misfocused frame among 300 is annoying; a series of 50 misfocused frames because AF drifted is devastating. Set manual focus once and do not touch it.
Taking It Further
Composite stacking. Take your best 3 to 5 bolt captures from a single storm and blend them in post-processing to create an image with multiple bolts across the sky. Since each frame shares the same composition and camera position, they layer together naturally. Use lighten blending mode to combine only the bright bolt elements.
Lightning over water. Find a vantage point overlooking a lake, river, or ocean with a storm approaching across the water. Bolts reflecting off the water surface double the visual impact. Use a slightly longer focal length (35-50mm) to compress the reflection closer to the bolt.
Anvil crawlers and sheet lightning. Not all lightning photography is about cloud-to-ground bolts. Anvil crawlers — long, branching discharges that travel horizontally through the upper cloud layer — create sprawling, tree-like patterns across the sky. These are best captured with ultra-wide lenses (14-16mm) and are most common in the trailing region of large supercell thunderstorms.
Time-lapse lightning sequences. Your continuous long-exposure sequence is already a time-lapse dataset. Import all frames into time-lapse software and render a video at 24 or 30 fps. A two-hour shooting session becomes a 10 to 15-second video showing the storm’s progression, with bolts flashing dramatically across the sequence.
Storm chasing for better positioning. As you gain experience, consider mobile storm photography — driving to position yourself relative to storms as they develop and move. This requires serious weather knowledge, a reliable vehicle, and a safety-first mindset. Storm spotting courses taught by organizations like SKYWARN provide foundational knowledge.
