Photographer Debbie Parker captured this #lightning strike in West Virginia. - Author: sco-go #photo #weather #storm #nature #ecology #earth

@nando161
Rather than repeating your undescriptive post in alt text why not actuary describe it like you might, if say you were trying to explain it to a friend who couldn't see it for whatever reason 🤷🙂.

There's an #AltBot if you need it (but defo check it for mistakes / missing bits) or you could use the #ALT4me hashtag to see if anyone else would be willing to help out & write one. They'll probably use the #ALT4you tag to indicate their efforts.

Hope this info helps.

@nando161 @Nickiquote And THAT, children, is why we don’t stand under individual trees during a thunderstorm

@nando161 great pic 🙏

I offer the following ALT description:

A bolt of lightning zig zags through a murky sky and hits a tree in full leaf, left of centre of its canopy. It tracks along a branch to the trunk and follows it straight down to the ground. The whole tree is lit up by the lightning in an orange-yellow light. A small flash of fire extends a short way from the trunk into the grass at the base.

The tree stands apart from others in fields that stretch back to hills on the horizon.

@nando161 the moment you realize you forgot your keys at home:

But... Please examine all the details of the photo.

It is not the same frame ? The trees at the horizon seems different ...

Maybe an AI "enhanced" version

@mrv @nando161 Maybe it's just a particularly attractive tree, and it gets hit by lightning often. 😄

@nando161

7 differences game

@mrv @nando161 the hell with AI enhancements! The orignal has much more details why would anyone alter it is beyond my comprehension
@mrv @nando161
En fait cet arbre a été frappé 2 fois par la foudre 
@nando161 i would like to see the same picture 1 minute before this one and one minute after.
@beaufils as it seems to be a frame from a video you might be able to reach for the author and get what you want.

@pluralistic

Glorious. I'd love to know how they did it.

@tarheel @nando161 @pluralistic It's just a frame from a video recording. That's how most people catch lightning strikes.

@themaritimegirl

Man, there go my dreams of dozens of cameras in likely spots and ionization detection and....

It seems higher-res than I'm used to with frame grabs, but maybe I should get used to that now.

@nando161 @pluralistic

@tarheel @nando161 @pluralistic The magic of HD/4K/etc cameras :)
@tarheel @themaritimegirl @nando161 historically, if it was dark enough out, you’d just do a long (bulb) exposure on film and simply release once there was a strike… if it’s dark enough you’re not really building up too much of an exposure, but then a lot of light happens at once, as with using a strobe to capture motion, except with lightning (or fireworks) the light itself is what you want to capture.
@brhfl @tarheel @themaritimegirl @nando161
So like, a long exposure with an f-stop appropriate for something close to daylight?

@themaritimegirl @tarheel @nando161 @pluralistic

BTW, this image is AI generated...

This is the original, given as a model :

@mrv This is facinating; I wouldn't have known if I'd seen the AI one first that it was fake, but the real one feels so much more alive and... real than the fake one, in a way I can't account for - on the surface they both look extremely similar. Our brains pick up on so many little things without us realizing.

@themaritimegirl @tarheel @nando161 @pluralistic
There's also CHDK (for some Canon camera models) which has an auto trigger mode that can capture lightning strikes.

"Motion detection trigger - automatically fires camera on motion detection.
Ability to capture lightning strikes.'

CHDK Wiki

@dec23k @themaritimegirl @tarheel @nando161 @pluralistic I captured this with my Nikon D600 about 10 years ago. The old "continuous shooting mode, hold the shutter button down and hope" approach. I think I filled two SD cards and got ~4 usable images.
@ret @dec23k @themaritimegirl @tarheel @nando161 @pluralistic huh now im wondering if it'd be possible to do captures in like a ring buffer (like slow motion cameras) and trigger off a photodiode or something (or just the images assuming the processing wouldn't end up being too slow)

@ret @dec23k @themaritimegirl @tarheel @nando161 Canon + CHDK, or Samsung + NX-KS, or a simple external shutter with a lock switch.

Manual mode. Make the shutter time as long as possible (30s), low ISO, small aperture (clean your lens and check results for sensor dust). Underexpose (a shot without lightning should be just barely above black).

Shoot RAW if you can. Shoot in continuous shooting mode.

@tarheel

@nando161 @pluralistic

Lightning strikes are easy to capture with cameras. Set the aperture small (turn the amount of light captured per second very small) and take very long exposures (the amount of time that it takes to complete a photo). If there is lightning, it will photograph well.

Extraordinary 👏👏

@nando161

It struck not the highest branch but the branch offering the most efficient conductivity to the ground

@nando161 Always a poor tree and never a 7 iron in the middle of Trump's backswing
@nando161 Image description: A tall tree standing alone. The lightning striking it is wiggly until it reaches the treetop where it straightens out and travels down a bough and then straight down the trunk, lighting the crown orange from the inside.
@nando161 I wonder how much of the yellowing of the bolt as it enters the tree is from incandescence, and how much is from sodium in the plant cells
@nando161 that's one fine conductive tree
@jlgnt this is AI-generated ("enhanced"), not a real picture.
Wow thats very impressing
@nando161
J'ai vu dans mon village un arbre complètement explosé par la foudre, les habitants de la maison à moi de dix metres on eux très peur.
Toutes l'installation électrique a du être remplacée.
Complètement détruite.
@nando161
C'est une image superbe, et à la fois inquiétante.
