I’m not sure why, but I really like this one.

I figured if I just showed it as common hi, then anyone who wanted to take the idea could adapt it as necessary.

That’s what got me into trouble with my own circuit – I made the bad assumption that using a Pocket Wizard shutter trigger cable would “standardize” things for me.

It didn’t.

Might want to specify the camera for that schematic – for example, the Nikon D80 and the Nikon D300 invert the voltage across the tip and ring on standard Pocket Wizard-type shutter cables… it’s weird.

Keep watching, then – we’re expecting another spate of storms later this week… and I’ll probably be better prepared for them.

[caradoc]

Yes. A best-case 68ms would be good. 90ms would cut out a lot of strikes other than the “sky crawlers” that you can just watch moving across the clouds before they ground-strike.

8/100’s of a second? Dear God, man, how do you even measure such a thing?

Personally, I don’t – which is why I linked to that table…

But I know a guy who’s actually done exactly that with an oscilloscope, laser, and light sensor – record the signal that triggers, and record the spike from the light sensor when it picks up the reflected light after the shutter opens.

Upload picture in largest available resolution to said pools.

I don’t know that flickr can handle that.

“Largest available resolution” varies on Flickr by whether or not someone has a “Pro” account…

Have you measured the delay from trigger-to-shutter?

My D80 is 80ms from the signal to the shutter, and the Arduino controller is 1ms from detect-to-signal, so “staccato” lightning that lasts less than 81 ms simply won’t show up in the frame – but I’ll get a photo of the landscape anyway.

There’s a decent table of trigger-to-shutter delays by make/model here.

I have video, too: http://www.flickr.com/photos/iaincaradoc/4785216387/

A circular polarizer really helps with enhancing rainbow colors.

Yesterday was interesting, too:

I use an Arduino-based lightning detector to shoot these – it measures ambient infrared and triggers my shutter at any spike in IR.

After a screeching debate over who gets to use the birdbath…

…they seem to have reached an uneasy peace:

Ironically, on my way home tonight, the hookers were all on the second floor of the hotel.

Working their way up, eh?

[caradoc]

This one is priceless.

[caradoc]

I’ve considered not posting. But if I’d not posted, I wouldn’t have had a good showing last week.

So I just post. 😀 Can’t win if you don’t play and a’ o’ that.

[caradoc]

No. What’s behind them is the street – asphalt in direct sunlight, while the birds are in the dappled shade under the trees.
