How do they get such good pictures of lightening.

Or are they all lucky shoots.

Probably one of about 100 shots . The storms we had last friday had the lightning going every 20 seconds or so.

That one is just a 30 second or so exposure on a tripod, and a little bit of luck that the lightening strikes within the 30 seconds. Notice how it looks fairly light, just because the camera has been able to soak up loads of light while its been taking the pic, then whammo a bolt of lightening strikes through the pic as well.

You could get a more natural pic of the night sky with a shorter shutter - 5 seconds perhaps - but then you've a smaller window in which the strike must occur.

Could do, but you would need to know where it was going to strike, or you would have to be very close to where it did to trigger. They are designed to work with studio flashes not outside.

They're also very bright relative to a night sky, so in a 30 second exposure where the aperture is fully open you will see it on the finished photo.

Same as this pic



Massively blurred because of the long shutter, but a flash gun has been used to momentarily pick out the bike in mid air. Note how anything which was already fairly light in the pic - ie the writing on the tyre - is blurred as its there even without the flash, but other dark areas like his face and shirt are sharp as they're not lit naturally.

Thunderstorms can occur at any time of the year Ian. I remember last February when we had some crazy snowstorm, there was also thunder and lightning.
