Here is the way I do lightning photo`s using a DSLR camera at night.

Firstly a sturdy Tripod & a Cable Release or Remote Trigger will be needed.

Set the camera to Bulb.
Set the F stop at between f9 to f22, this will give a good depth of field for strikes that are close or in the distance.
Set the ISO to 100. Lower ISO`s will reduce the amount of "noise" in the image
Find a light in the distance to focus on or set the focus to Infinity.

Once the camera is set, press the release or trigger. Count to 30 & release. Keep repeating to get the shot.

Sometimes there can be several strikes in 30 seconds. One thing to keep in mind is that this can cause over exposure, making the final image to bright. With a bit of practice you will soon get a feel as to when to end the exposure. If you would like multible strikes in one shot, increase the exposure time & use a higher f stop.

I have never had much luck shooting during the day but a friend uses a "Lightning Trigger" & has had some good results.

Some Smartphones can take long exposures, so combined with a tripod & a Bluetooth remote it might be worth trying.

There are no set rules & it might take a bit of trial & error to get the results.





Remember that lightning can kill so take care when out shooting.
