Lightning Photo Tips

I used a Nikon print film 35mm SLR camera from the late 1980s then made the move to digital with a Nikon D70 digital SLR camera in June 2004, and have since upgraded to a Nikon D90 DSLR. I use ISO 200 for almost all lightning photos. The D70 came with an 18-70mm kit lens, however I mostly used an old manual focus 50mm lens for lightning as it has aperture to F1.8 and precise infinity focusing. I currently use a 18-200mm VR lens on the D90 and a F1.4 50mm lens.

Despite lightning itself being very bright, the more overall scene light you let in, the better the picture (in most cases), so use lower F settings at night. Zooming in on distant lightning often produces disappointing results.

Ideally, for both night and late afternoon / early evening lightning you need a camera that can be mounted on a tripod and have a cable/remote shutter release. If you don't have a tripod you can set the camera up on other available surfaces - eg. a table or car roof. The cable/remote is used to ensure there is no bumping or shaking of the camera when the shutter button is pressed. If you don't have a remote another option is to use the camera's self-timer option so that a few seconds elapse between pressing the shutter and the exposure commencing.

Locking the focus at infinity

You do not want the camera searching for focus when trying to take pictures of lightning - so you need to set it to infinity first. Any slightly out of focus shots of lightning are very noticeable with digital.

  • Compact Digital Cameras: Most of the compact digital cameras I have come across have an option to force the focus to infinity - so it is quite easy to lock the focus at infinity on those cameras - just find it on the menu or in the scenes dial.
  • Digital SLRs: Obtaining infinity focus at night with a digital SLR and autofocus lens is more complicated. To find infinity at night you can use the autofocus system to try and focus on a distant light source then switch the lens to manual focus once this is found. An option is to turn your car's lights on, walk some distance away - then focus on those lights. If you cannot get the autofocus mechanism to work you will have to manually focus the lens. A problem with most autofocus lenses is that they either have no infinity marker (sideways 8 symbol) or the centre of the infinity marker is not really infinity! On my Nikkor 18-200mm kens, infinity is slightly to the right of the infinity mark. A bit of trial and error may be required. A tip is to experiment with focusing during the day and note where the autofocus system locates infinity. Another option (which I use) is to obtain an old manual focus lens that has precise infinity - rotating the focusing ring to the far left and it is infinity.

Lightning Triggers

Night Time Lightning Photography

  • Set your camera on a tripod.
  • Connect a cable shutter release or set the remote for taking the shots.
  • Lock focus at infinity.
  • Set the shutter speed to bulb 'B' (the shutter will stay open for as long as you hold it open). If you don't have this option, set the exposure time to the longest possible - realistically you need 10 to 30 seconds
  • Set the aperture (F-stop) to between F2.8 and F5.6. Experiment a little with different settings but I recommend nothing higher than F8 unless you want many bolts of lightning to occur in the one photo.
  • Frame the picture where the most lightning is occurring, or where the most spectacular clouds are.
  • Observe the lightning for a short while before taking a picture. You will notice that some cloud to ground (CG) lightning strikes very fast (in a fraction of a second it has flashed and gone). Other CG bolts strobe or pulse for anything up to 2 seconds. Sheet lightning (anvil crawlers) sometimes lasts up to a second or more as it spreads across the sky. If the storm is close to you and/or you can see it growing or moving, then exposure times should be at most 15 seconds, or else the cloud will blur (especially if more than one lightning bolt occurs during the exposure). If the storm is a fair way away, you are only framing the storm base, or you cannot see it developing or moving, then exposures can be anything you like! I recommend between 20 seconds and 2 minutes. You can have longer exposure times for higher F stops.
  • For the 'fast' lightning:

    - Press the cable/remote to open the shutter.
    - Wait for the lightning (or multiple lightning) to occur within the frame of your shot.
    - Release the shutter.
  • For the longer lasting lightning:

    - You can do the same as above, or
    - Wait for the lightning to occur.
    - Press the cable/remote to open the shutter as soon as you see the flash.
    - Release the shutter after a number of seconds (up to you).

Late Afternoon or Early Morning (low daylight) Lightning Photography

  • Set your camera on a tripod.
  • Connect a cable shutter release or set the remote for taking the shots.
  • Set focus to infinity.
  • Set the shutter speed to 'B' if you want to control the length of the exposure, otherwise I recommend setting the speed to aperture priority setting if you have this.
  • Set the aperture (F-stop) higher (experiment with F5.6 - F16) than for night shots - it will give you more exposure time, and more chance of capturing the lightning.
  • Frame the picture where the most lightning is occurring, or where the most spectacular clouds are.
  • Either wait for the lightning to occur then press the cable/remote to open the shutter, or press the cable/remote and hope that lighting occurs reasonably quickly.
  • If you have set the speed to automatic then that's it, otherwise, release the shutter after your estimated exposure time.

Day Time Lightning Photography

There isn't much to tell you here, you have to react quickly and be pointing the camera in the right direction. Observe the lightning before you attempt any shots - if all the bolts are very fast and do not strobe, then you will not be able to react fast enough.

  • Use a normal landscape dial setting, or set the aperture and the exposure time to what you prefer, as you would with any other day time photograph.
  • Lock focus at infinity - you do not want the camera searching for focus before actually taking the picture
  • Aim.
  • Wait for the lightning!! If you react quickly enough when you see the bolt, you may capture it.

Continuous Shooting

There is another technique you can try for lightning photography. If your camera has a fast continuous shooting mode - you can always just do a continuous shoot and hope that lightning occurs during that time. It does require a lot of discarding of images afterwards, but you may be rewarded with a fully branched daytime CG lightning picture!

Lightning Triggers

I've had the opportunity to use a lightning trigger the past two thunderstorm seasons. There is no doubt that they will help you capture lightning that you just wouldn't be able to otherwise get. These daytime shots were obtained using a lightning trigger. You use the same photographic techniques described in the daytime and late afternoon tips section, but let the trigger do the work thereafter.

There's usually no need to use a lightning trigger at night as you can use the night time lightning techniques described above which are very effective.
