STORM FILE · Stormchasing

You do not have to press the shutter at the exact moment lightning strikes. At night, the camera can already be exposing when the flash appears. In daylight, the bright surroundings make this harder. Here is how I prepare my camera, the settings I start with and what to watch for on your first attempts. This guide covers cameras; phones deserve their own article.

01 / FIELD NOTE

Choose a safe place and a way back first

An open view of the sky helps, but do not choose an exposed hilltop, tower or other unprotected position. A lone tree, open shelter or tent will not protect you from lightning either. Plan your shot so you do not have to set up outside or wait for another flash when the storm is close.

As soon as you hear thunder, stop shooting outdoors and go into a substantial building or a fully enclosed vehicle with a metal roof. Stay there for at least 30 minutes after the last thunder. Keep the car windows closed. Fewer flashes, easing rain or a weather app do not mean it is safe. Actively intercepting storms is not a good first step when you are learning the camera technique.

02 / FIELD NOTE

This equipment is enough to get started

I use a Sony a6600 with a wide-angle lens and a tripod. This guide is not tied to that camera. What matters is manual exposure, manual focus and a stable setup.

  • A camera with manual mode and a charged battery.
  • A tripod that keeps the camera steady in the wind.
  • A wide-angle lens to capture a larger part of the sky.
  • A remote shutter release or the camera’s self-timer.
  • Optional for daylight: an ND filter and a lightning trigger compatible with your camera.

Frame the shot and set focus

Point the camera towards the part of the sky where you can see lightning. A slightly wider frame gives you more room if the next flash appears elsewhere. A suitable foreground is nice, but you cannot always find one on location. There is no need to move to a less safe position for a more elaborate composition.

Focus manually on something far away. In the dark, infinity is a starting point, not a guarantee of a sharp image. If you can see a distant light or a clear edge of a building, use the viewfinder or screen magnification to check focus there. With an ND1000 filter, this is usually easier before you fit the filter. Check the focus again afterwards and do not let the camera hunt for focus with every shot. Guidance on manual focus for lightning photographs.

04 / FIELD NOTE

Start with a long exposure at night

In the dark, I use exposures of up to 30 seconds, often at f/8. I adjust ISO to the ambient light; my personal upper limit is around 1200. For a first attempt, I would start much lower. These are starting points, not fixed settings for every storm.

SettingStarting point
Exposure modeManual, usually marked M
Aperturef/8
ISOStart at 100; increase only if needed
Exposure timeStart around 10–15 seconds; shorter or up to 30 seconds depending on ambient light
FocusManual, checked on a distant subject

Take a test shot first. If the sky is too bright even without lightning, shorten the exposure or lower ISO. If a captured flash is blown out and loses detail, try a lower ISO or a smaller aperture, such as f/11 instead of f/8. A longer exposure mainly gathers more ambient light; it does not make the lightning last longer. After your first successful shots, check both the lightning and the background.

During a long exposure, the camera is already recording when lightning strikes. The marked times are examples only.

At night, lightning stands out against a dark background. Its brightness still has to suit the exposure.

05 / FIELD NOTE

Release the shutter without moving the camera

Pressing the shutter button can briefly shake the camera on its tripod. Use a remote release if you have one. Otherwise, a short self-timer delay helps. The Sony a6600 has a two-second timer for this. It gives the camera a moment to settle after you press the button. A shot taken without a remote is not automatically blurred. Sony a6600: self-timer.

A lightning trigger differs from an ordinary remote release: it detects a rapid change in brightness and sends a shutter signal to the camera. This can be especially useful in daylight. Focus and exposure still have to be right beforehand. The trigger, cable and camera must be compatible, and even then it will not catch every flash.

06 / FIELD NOTE

Try an ND1000 filter in daylight

In daylight, I try an ND1000 filter. It reduces the light by about ten stops and makes longer exposures possible. If a suitable exposure without the filter is 1/100 second, the same aperture and ISO give roughly ten seconds with the filter. That is a calculation example, not a setting that works in every daylight situation. HOYA: ND1000 and light reduction.

The filter also dims the lightning. A weak or distant flash may barely show up. A longer exposure alone cannot compensate for this brief event. It is worth trying, but a strong ND filter is no guarantee of success. A suitable lightning trigger can be an alternative for shooting with a shorter exposure.

Schematic comparison with and without an ND1000 filter: both daylight and lightning are reduced; the longer exposure window does not automatically make a brief flash brighter.
An ND filter allows a longer exposure, but it also reduces the light from the lightning.

07 / FIELD NOTE

Check your first shots

Zoom in on a shot on the camera screen. Check whether fixed outlines are sharp, whether the lightning retains detail and whether raindrops cover the front element. Change just one setting at a time if you can. That way you can see what the change did. You may need new test shots as the ambient light changes.

In long exposures, I often like wind turbines less than I do with the naked eye. Their blades keep moving and become blurred or appear as smeared shapes. The red warning lights can stand out in the picture. That is not a camera fault. If this effect does not suit the image, try a different frame if you can do so from your chosen location.

08 / FIELD NOTE

Fewer flashes do not mean it is safe

If lightning rarely appears in your frame, waiting longer may no longer be worthwhile for the photograph. That does not make the storm safe. The number of visible flashes is not a reliable measure for deciding whether it is safe to be outside. One flash in ten minutes certainly does not prove that outdoor photography is safe again.

To get started, prepare the camera, tune the exposure with test shots and check the results. Not every frame will contain lightning. That is normal with this technique.

09 / FIELD NOTE

Before you shoot: a short checklist

  1. Check the weather and where you can take shelter. Do not photograph outdoors when you can hear thunder.
  2. Set up the camera securely, choose your frame and focus manually.
  3. At night, start with a low ISO, around f/8 and a suitable exposure time. Adjust after a test shot.
  4. Use a remote release or a short self-timer delay.
  5. Zoom in on successful shots and check sharpness, lightning and background separately.
