Jestli se nemejlim, tak je to prohnany pres plugin photoshopu, nejaky KPTcka to umely moooc pekne. a byl to presne tenhle styl.

Ja nevim, v grafice se zrovna nevyznam, ale nepripadne mi, ze by photoshop dokazal nasvitit kazdy jednotlivy listecek na vsech stromech a na vsech objektech, ktery se na fotce nachazeji... Staci se podivat na originalni fotku, podle mne by to bylo nemozny. A proc by to delal clovek, ktery polovinu sveho zivota foti elektricke vyboje, oblouky, blesky...? Osobne si myslim, ze by to bylo proti jeho presvedceni.

Tady je popis co to je a jak ta fotka vznikla:

The above photo is courtesy of Kane Quinnell from Australia. It was almost his last. The above lightning stroke was almost certainly a "bolt from the blue" - a relatively rare positive lightning bolt that originates from the top of a distant storm cloud rather than from the negatively charged cloud base. These massive discharges can travel horizontally for 10 miles or more from the center of the main storm. They pack peak currents of up to 340,000 amperes, and they last for tens or even hundreds of milliseconds. This is about ten times more current and ten times longer than regular (negative) lightning. Positive lightning is extremely hot, it does considerable damage to whatever it hits, and if you happen to be unlucky enough to get hit by one of these monster bolts, you DO NOT survive. Here's his description of what happened:

"I happened to be out in the back yard, watching a storm on Friday night (14/01/05) that appeared to be a few km away, (I live in Old Toongabbie, and the storm appeared to be in Pendle Hill, or Greystanes, Australia). I set the camera's settings so that the shutter remained open for four seconds, placed it on the back bumper of my car, hoping to get a few shots of lightning in the clouds a few km's away. There was no rain at all, and stars could be seen over the north 1/3 of the sky, so I did not feel in danger in any way. Boy was I mistaken... DO NOT UNDERESTIMATE ELECTRICAL STORMS - YOU COULD GET YOURSELF KILLED!

I clicked away a few times, and got nothing, and then clicked the button again, and within 0.5 seconds of me pressing the button, I had jumped at least 2 metres in the air, as I heard a tremendously loud crack of thunder, and see this amazingly bright beam of electricity right in front of me. I had then landed, grabbed the camera, and was inside the house within 2 seconds.

I did not realize just how lucky I was until I uploaded the picture to my computer, and saw a leader stroke that must have originated no more than 2 metres from where I was standing next to my car, under my carport. Had the main charge taken the leader near me, rather than the one it did, I would be dead.

When lightning strikes, it actually comes up from the ground first (called a leader stroke), this stroke makes the air within it conductive, and once it reaches the cloud, you have a complete circuit, and the bolt of lightning comes down from the cloud along the leader stroke. First leader to the cloud wins, luckily mine did not.

I estimate that the main bolt was approximately 1.5- 2 metres in diameter, and struck something in the yard behind the shed that is located at the back of the yard. That would have had an extremely large charge, and would have been extremely hot, hotter than the surface of the sun, at 5,500 degrees Celsius, it could have been around 30,000 degrees Celsius. Needless to say, I was buzzing for the rest of Friday night, due to the amount of adrenaline going through me 'cause of how close it had come."

Kane Quinnell was one very lucky bloke!
